In over crossings of public waters, lines shall have a minimum clearance of 25 feet above extreme high water, unless otherwise approved by the Regional Operations Supervisor. B. As directed by the Regional Operations Supervisor, marker spheres shall be placed on overhead utility lines directly above the protected water. C. Any cable or conduit located at a shoreline shall be sufficiently buried at the shoreline so as to prevent its becoming exposed during droughts or winter drawdowns. D. As directed by the Regional Operations Supervisor, underwater crossings shall be marked by permanent signs on the banks at points where the line enters and leaves the protected water. 11. Unless otherwise authorized by the Regional Operations. Supervisor, shut-off valves shall be installed within a pipeline on each side of the water crossing to provide an effective means of halting the release of product or effluent from the line into the surface waters in the event of a line rupture. 12. To protect fish spawning activities, the commissioner may prohibit work in the stream or work within a specified distance of the protected water during the spawning season. 13. Licensee must minimize disturbance to natural streambed and shoreline vegetation, including trees and shrubs. Allowable clearing of banks, shorelines and land adjacent to them is restricted to the minimum necessary for equipment to complete the installation; banks, shorelines and land adjacent to them should not be cleared to the full right-of-way width. 14. The beds of the waters described above shall, upon completion of construction or maintenance operations therein, be restored as nearly as practicable to their original cross-section. Extreme care shall be exercised to assure that the contours and elevations of the streambed are not changed by this installation in any manner that would alter the runout elevation of any public waters basins located upstream of the crossing. 15. Erosion: A. Erosion control measures shall be employed to stabilize the banks. Where necessary to prevent erosion, streambeds shall be permanently riprapped with natural rock having an average diameter of 12 inches. B.

They shall be installed prior to commencement and maintained throughout the project. All erosion control fences next to a water body shall run parallel to the contours. C. Under low flow conditions, the work, as approved by the commissioner, shall be done to minimize erosion and siltation caused by construction. D. If downstream bank erosion commences, immediate erosion control measures shall be taken and the Regional Operations Supervisor notified immediately. E. Any work below water level shall be encircled by a flotation sediment curtain or other suitable sediment containment device to prevent sediment from being transported beyond the excavation area. F. All disturbed areas shall be stabilized as soon as possible following construction. Topsoil shall be used to re- dress disturbed soil areas, and indigenous plant species should be used, whenever possible, to revegetate disturbed areas. This revegetation should occur as early in the season as possible to permit adequate regrowth. G. Excavated materials shall not be deposited or stored alongside a protected water in a manner where the materials can be redeposited into the protected water by reasonably expected high water or storm run-off. 16.

The manual provides a basic guide to the seed mixtures that Mn/DOT typically specifies and the methods for placement. For detailed seeding and mulch recommendations, refer to the individual Mn/DOT district seeding recommendations. Seed Mixture Changes The seed mixtures described in Mn/DOT's 2000 Standard Specifications for Construction are still being specified and used on construction projects. These seed mixtures are designated with a letter B following the number (B-series). Some of these mixtures are being dropped, some are being phased out and some will continue to be used. For mixtures being phased out or dropped, new seed mixtures have been developed to replace them. The new mixtures have higher rates of cover crop to provide quicker erosion control and are also generally more cost effective. All A-series (1995) mixtures should no longer be specified. New seed mixtures have been numbered in such a manner that all mixtures in the 100's are temporary cover, 200's are general seed mixtures, and 300's are native seed mixtures. Wetland Restoration For information regarding wetland restoration seeding, contact Bob Jacobson at 651-284-3767 or by email at robert.jacobson(a~dot.state.mn.us. Bob has developed wetland and upland buffer restoration mixes in consultation with staff from the Board of Soil & Water Resources (BSWR) to meet specific wetland delineation requirements. BWSR has also developed. a number of mixes for use on RIM and CREP projects. They are in essence "boiled down" versions of our Mn/DOT mixtures. The main difference being they contain fewer species. They can be found at BWSR's website under "native seed mix recommendations". The file is a PDF file.

Note that within each mixture tabulation, at the end of this manual, there is a brief description of the mix and what it was developed for. All mixtures with a letter "B" can be found in Mn/DOT's 2000 Standard Specifications for Construction; all other mixtures are currently specified through special provisions. The seeding rates listed are for roadside establishment and initial erosion control. The rates are somewhat higher than rates used for seeding parkland fields and other non-roadside areas. Table 1.

Table 2 lists the general dates when seeding of various Mn/DOT mixes should occur. Seasons can be extended based on the current weather patterns, such as frequent low intensity rainfalls with cooler than average temperatures. Dormant Seeding- When dormant seeding, it is important to note different species are dormant at different times of the year. Dormant seeding for warm-season grasses occurs in early fall as they require 65 degree F and above sustained soil temperatures and moisture to germinate. Cool-season grasses will germinate at colder temperatures and generally in a shorter period of time. Many fortis will not germinate at all the first year when seeded in the spring as they require afreeze/thaw period (winter) to germinate. Thus, fortis may not appear until the following spring. Dormant seeding is somewhat risky due to factors such as weather, snow cover, predation, and soil erosion. However, plantings do appear to contain more diversity ofcool-season grasses and fortis when installed in the fall. Table 2.

Mn/DOT Seeding Manua12003 (Page 22) Establishing General Seed Mixtures General Recommendations -Seeding general mixtures can be accomplished using a number of different methods from mechanical means to hydroseeding. One key to a successful establishment is preparing the soil bed. Immediately before seeding, the soil should be tilled to a minimum depth of 3". The tillage will help improve seed-to-soil contact as well as increase the amount of initial infiltration giving the seeds moisture to begin establishment. General seed mixtures include SOB through 130B within the 2000 Standard Specifications for Construction as well as the new seed mixtures 150 through 280. The new seed mixtures were developed due to a large number of requests to move back towards the 1988 Specification's seed mixtures. Thus, seed mixture 250 is similar to the 1988 Specification's 500 seed mixture and 280 is similar to the 1988 Specification's 800 seed mixture. Temporary Erosion Control -Immediately after seeding, within 24 hours, mulch should be applied to protect and enhance seed germination. In most cases on slopes 1:3 (Vertical:Horizontal) and flatter Mn/DOT Type 1 mulch (see specification below) at 90% soil coverage is applied. This generally requires about 2 tons per acre of straw mulch. If mulch applications are placed too heavily, it can hinder germination or smother new seedlings. In areas with weed concerns, it is recommended to use high quality weed free mulch such as MCIA Certified Weed Free mulch. See Native Grass section for example Mn/DOT Type 3 specification. On slopes that are temporary in nature, have limited access, or are stockpiles consider using Mn/DOT Type 6 Hydraulic Soil Stabilizer (see specification below) at 25001bs/acre. On slopes that are steeper than 1:3 or in ditch bottoms it is recommended that the seeding be covered with an erosion control blanket. The erosion control blanket should contain netting on both sides and be composed of straw, astraw/coconut blend, or wood fibers. Under more strenuous conditions such as slopes steeper than 1:2, ditch bottoms experiencing flow velocities greater than 7 feet/second or ditch grades 5% or more specialized treatments not covered in this manual should be used. Generic Specification Examples: Mn/DOT Type 1 Mulch -This mulch shall consist of grain straw, hay, cuttings of agricultural grasses and legumes. The material shall be free of seed bearing stalks of noxious grasses or weeds as defined by the rules and regulations of the Minnesota Department of Agriculture. In addition, mulch shall not contain the following species: cattail, reed canary grass, birds-foot trefoil or crown vetch. At the time of delivery the mulch shall be in an air-dried condition. Mn/DOT Type 6 Hydraulic Soil Stabilizer -Type 6 shall be a blend of 40 to 60% recycled paper and 40 to 60% wood cellulose fibers by weight. The fibers shall contain no germination or growth inhibiting factors. It shall not contain nor be processed from sawdust or pulverized newspaper. It shall be dyed an appropriate color to allow visual metering of its application, and shall have the property of becoming dispersed and suspended when agitated in water. It shall contain 2.5 to 5% tackifier by weight. The tackifier shall be incidental to the Type 6 hydromulch material. When sprayed uniformly on the surface of the soil, the fibers shall form ablotter-like ground cover that readily absorbs water and allows infiltration to the underlying soil. Moisture content shall not exceed 15% at the time of delivery. When washed on a 850µm sieve at least 50% shall be retained on the sieve. Fertilizer - It is always recommended to take soil tests to determine the existing soil fertility in order to chose an appropriate fertilizer based on the soil deficiencies. If you are going to use a generic fertilizer Mn/DOT Seeding Manua12003 (Page 23) it is recommended to use a 24-12-24 NPK analysis fertilizer at 300 lbs/acre. In areas where a Phosphorus free fertilizer is desired a 23-0-30 analysis at a rate of 2001bs/acre is recommended. Seeding Methods Method 1. Drop Seeding Onto Tilled Sites -This is the "standard" method for seeding on prepared sites such as those on construction projects. A) .Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. B) Fertilizer -Either use a fertilizer analysis based on a soil test or a general recommendation is a 24-12-24 (NPK) commercial grade analysis at 300 lbs/acre. C) Seed Installation -Seed should be installed with a drop seeder that will accurately meter the types of seed to be planted, keep all seeds uniformly mixed during the seeding and contain drop seed tubes for seed placement (Brillion-type). The drop seeder should be equipped with a cultipacker assembly to ensure seed-to-soil contact. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Packing - If the drop seeder is not equipped with a cultipacker, the site should be cultipacked following the seeding to ensure seed-to-soil contact. F) Mulch -The site should be mulched and disc-anchored following cultipacking. The standard mulch is Mn/DOT Type 1 at a rate of 2.0 tons/acre. Also see temporary erosion control for additional information. Method 2. Hydroseeding -Hydroseeding is an acceptable method for establishing the general mixtures when it is done correctly. However, it is imperative that the site is prepared and finished properly. Mn/DOT generally uses hydroseeding on steep slopes or other areas inaccessible to a drop seeder such as wetland edges and ponds. Hydroseeding is not recommended if the extended weather patterns are hot and dry and the soil surface is dry and dusty. The seed-water slurry should be applied within one hour after the seed is added to the hydroseeder tank. A) Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. It is critical that the seedbed be loosened to a point that there are a lot of spaces for seed to filter into cracks and crevices otherwise it may end up on the surface and wash away with the first heavy rain. B) Fertilizer -Either use a fertilizer analysis based on a soil test or a general recommendation is a 24-12-24 (NPK) commercial grade analysis at 3001bs/acre. C) Seed Installation -Seed should be installed by hydro-seeding it evenly over the entire site. A fan-type nozzle should be used with approximately 500 gallons of water per acre. It is recommended to add approximately 75 pounds of hydromulch per 500 gallons of water for a visual tracer to ensure uniform coverage. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Harrowing -The site should be harrowed, cultipacked or raked following seeding. F) Mulch -The site should be mulched following harrowing using one of the following methods (as per plans or special provisions): • Mn/DOT Type 1 mulch at a rate of 2.0 tons per acre with disc anchoring. • Mn/DOT Hydraulic Soil Stabilizer or Bonded Fiber Matrix on inaccessible sites. NOTE: When seeding in conjunction with a hydraulic soil stabilizer (bonded fiber matrixes (BFM's), hydro-mulches, etc., it is recommended that atwo-step operation be used. Seed should be placed first Mn/DOT Seeding Manua12003 (Page 24) and the hydraulic soil stabilizer be applied afterwards. This is to ensure that seed comes into direct contact with the soil. Method 3. Broadcast Seeding -Broadcast seeding is performed either with mechanical "cyclone" seeders, by hand seeding or by any other method that scatters seed over the soil surface. It is essential that steps be taken to ensure good seed to soil contact when broadcast seeding is used. A) Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. It is critical that the seedbed be loosened to a point that there are spaces for seed to filter into cracks and crevices otherwise it may end up on the surface and wash away with the first heavy rain. B) Fertilizer -Either use a fertilizer analysis based on a soil test or a general recommendation is a 24-12-24 (NPK) commercial grade analysis at 3001bs/acre. C) Seed Installation -Seed should be installed by broadcasting it evenly over the entire site. Several types and sizes of broadcast seeders are available for use, ranging from fertilizer-type spreaders to power spreaders mounted on all terrain vehicles. Seed should be mixed thoroughly prior to seeding and should be mixed occasionally in the spreader to prevent separation and settling. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Harrowing -The site should be harrowed or raked following seeding. F) Packing -The site should be cultipacked following harrowing. G) Mulch -The site should be mulched following packing using one of the following types of mulch (as per plans or special provisions): • Mn/DOT Type 1 mulch at a rate of 2.0 tons per acre followed by disc anchoring. • Mn/DOT Hydraulic Soil Stabilizer or Bonded Fiber Matrix on inaccessible sites. Method 4. Interseeding Into Existing Vegetation or Mulch -This method is generally used for sites that did not establish well or if a temporary mulch was applied to the site. An interseeder drill can be used to plant the. seed without removing or tilling the existing vegetation or mulch. A) Site Preparation For Existing Vegetation- The site should be prepared by mowing existing vegetation to a height of 4-6 inches. The area can then be directly planted using an interseeding drill. NOTE: Sites that contain significant weed infestations may require weed control measures before planting. After mowing, a herbicide application with glyphosate should be used. Addition of a surfactant and/or addition of 2,4-D to the mix often results in a more complete kill, especially with unwanted broad-leaved species. Recommended herbicide rates are 2.0 quarts/acre of glyphosate and 1.0 - 2.0 quarts/acre 2,4-D. Seeding can be performed 7-10 days after herbicide application. Other broadleaf herbicides can also be used such as Trimec, Transline, Stinger, etc. Follow the label directions. B) Fertilizer -Either use a fertilizer analysis based on a soil test or a general recommendation is a 24-12-24 (NPK) commercial grade analysis at 3001bs/acre. C) Seed Installation -The seed mixture should be installed with a seed drill that will accurately meter the seed to be planted and keep all seeds uniformly mixed during the drilling. The drill should contain a legume box for small seeds, and it should be equipped with disc furrow openers and packer assembly to compact the soil directly over the drill rows. Maximum row spacing should be 8 inches. The inter-seeder drill must be out-fitted with trash rippers that will slice through the vegetative mat and make a furrow into the underlying soil approximately 1 inch wide by 1/2 to 1 inch deep. These furrows shall be directly in line with the drill seed disc openers. Mn/DOT Seeding Manual 2003 (Page 26) Establishing Native Grasses and Fortis General Recommendations -Seeding native grasses and fortis (wildflowers) can be accomplished using a number of different methods. However, due to the complexity of seed sizes, textures and densities, a great deal of care needs to be taken to ensure that the site is well prepared and that seed is placed properly. A number of different types of drills may be used to place seed, but be aware that many "older style" drills will clog easily with fluffy seeds. Broadcast seeding and hydroseeding also work well, but remember that natives cannot be seeded exactly the same as turf grasses. There are several general "rules of thumb" to keep. in mind when seeding natives: • Native seeds prefer a firm seedbed. • Large and/or fluffy seeds should be buried approximately 1/4 inch deep. • Seed should be lightly covered with soil. Harrowing or raking works well. • Small and/or fine seeds (most fortis) should be scattered over the soil surface. Native Grass and Forb Mixtures -Seed mixtures SB through 28B within the 2000 Standard Specifications for Construction as well as new seed mixtures 310 through 350 are native/forb mixtures. These mixtures consist ofwarm-season native grasses, cool-season native grasses, native fortis (wildflowers} and annual or short-term cover crops. The new mixtures have a higher cover crop rate to provide increased erosion protection. A deliberate attempt has been made to have a large number of different grasses and fortis as it has been shown that diverse plantings are more resistant to drought, floods, and pathogens than monotypic or low diversity plantings. The inclusion of a diverse mixture of fortis is greatly beneficial to wildlife and the fortis occupy niches that would otherwise be occupied by weeds such as Canada thistle, musk thistle, bull thistle and sow thistle. The native legumes also fix nitrogen, which is made available to other plants in the system through fungal interactions between plants. Cool-season native grasses tend to establish quickly and will decrease over time on sites where warm-season species would normally dominate. Warm-season native grasses tend to be slower to establish, but are extremely hardy and long-lived. Warm-season grasses also tend to stay standing over the winter and provide the best snow filtering capabilities and wildlife habitat. In addition to planting a large diversity of species, we recommend using local ecotype plant materials. The origin of local ecotypes can be guaranteed by purchasing "Yellow Tag" certified native seeds. The Minnesota Crop Improvement Association (MCIA) works with local seed producers to certify that the origin of their products is local (see below for specification). NOTE: Seed certified to be Zone 1 (northern Iowa ecotype) is acceptable for use in southern Minnesota, seed certified to be of eastern ND and SD origin is acceptable for use in Western MN, and seed certified to be of Western WI origin is acceptable for use in eastern MN. Generic Specification Example: MCIA Yellow Tag Certified Seed Requirements -Native species shall have their origin documented by the Minnesota Crop Improvement Association (MCIA). This level of certification is at the "Yellow Tag" level according to the MCIA Quality Control program. Documentation verifying the origin of this seed shall be provided to the Engineer/Project Manager at least 30 days prior to the installation date. In the event that certain species may not be available as certified, those species may be supplied by a MCIA Certified Approved Collector/Producer along with documentation demonstrating the origin of those materials. All substitutions are subject to the approval of the Engineer/Project Manager. Mn/DOT Seeding Manual 2003 (Page 27) Cover/nurse Crops -Cover crops provide a quick short-term vegetative cover while the permanent native species are establishing. A cover crop reduces the soils erosion potential and moderates the native seedlings microclimate during establishment. Typical cover crops in Mn/DOT's native mixes include oats/winter wheat, annual rye grass and slender wheatgrass. Winter wheat is substituted for oats during fall plantings. The annual rye grass provides good cover in early spring but does not do well in late spring and summer. It also does well dormant seeded. ReGreen (a hybrid cross between slender wheat grass and winter wheat) listed in the 2000 Specification B-series mixtures is used instead of oats/winter wheat for temporary cover (ReGreen will persist for up to three years). Native species seeded in the fall perform very well, but it is critical that winter wheat (or ReGreen) and annual rye grass be used as specified in the mixes to ensure adequate vegetation establishment on erodible sites. One drawback Mn/DOT has observed to ReGreen that is that it does not perform very well in saturated soils, shaded areas, or when it is interseeded into dead sod. NOTE: The new native seed mixtures (310 - 350) have a much higher cover crop rate as compared to the 2000 B-series mixtures. When comparing seeding rates, note that 85% of the new mixture rates as compared to approximately 50% of the 2000 B-series mixtures are comprised of cover crop species. Cover crop species are inexpensive. Temporary Erosion Control - It is recommended to protect a new seeding by covering it with mulch or an erosion control blanket. In general, slopes that are 1:3 (vertical :horizontal) and flatter should be mulched with a clean grain straw or native grass mulch and disc anchored following seeding. Mulching should attempt to achieve 90% coverage of the exposed soil surface. This generally requires about 2 tons per acre of straw mulch. It is also recommended to use a high quality weed free mulch such as MCIA Certified Weed Free mulch (see below for specification) or a native grass (prairie) mulch. On slopes that are steeper than 1:3 it is recommended that the seeding be covered with an erosion control blanket. Generally, straw blankets containing double netting (Straw 2S) perform best with native plantings. If seeding is being done in a ditch or Swale that will receive moderate water flows for periods of time, it is recommended that astraw/coconut blanket be used to cover it. Other more severe situations such as very steep slopes and/or channels exposed to high water velocities will require more specialized treatments that are not covered in this manual. NOTE: Mulches derived from pasture hay containing reed canary grass, smooth brome and other introduced forage species may contain enough seed of those species to ruin your native grass and forb planting. They are not recommended for use with native plantings. Generic Specification Example: Mn/DOT Type 3 (MCIA Certified Weed Free Mulch) -This mulch shall consist of clean grain straw and be certified by the Minnesota Crop Improvement Association (MCIA) to be free of noxious weed seeds, seed bearing stalks, and/or other reproductive propagules as defined by rules and regulations of the Minnesota Department of Agriculture. Documentation verifying that the mulch has passed MCIA field inspection shall accompany the material upon delivery to the job site. At the time of delivery, the mulch shall be in an air dried condition. Fertilizer - It is always recommended to take soil tests to determine the existing soil fertility in order to chose an appropriate fertilizer based on the soil deficiencies. It is also recommended to chose a slow Mn/DOT Seeding Manual 2003 (Page 28) release fertilizer with 80% Water Insoluble Nitrogen (WIN) and 0% chlorides. If you are going to use a generic fertilizer it is recommended to use a 10-10-20 NPK analysis fertilizer (see below for specification. A general rule of thumb is that native grasses and fortis require about 50% less Nitrogen and 25% more Potassium than turf and forage species. Generic Specification Example: Fertilizer (Type Slow Release) -The fertilizer used for this project shall be a commercial grade of slow release complete fertilizer applied at a rate of 400 lbs/acre at the time of preparing the seed bed for seeding. The fertilizer shall contain a 10-10-20 (NPK) analysis, consisting of 80% Water Insoluble Nitrogen, 0% Chlorides, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). Seeding Into Agricultural Fields -Many fields that have been row cropped will have some amount of herbicide residue present, depending on what the crop was and what type of herbicide was used on the site to control weeds. Leaving the site fallow, or planting a temporary cover for a season before planting, will help reduce herbicide residue. Also be aware that herbicides used to control annual grasses may adversely affect native grasses being planted and broad-leaved herbicides may adversely affect fortis being planted. Inoculants - A number of inoculants are available in the marketplace. Native legumes form an association with nitrogen fixing bacteria of the genus Rhizobium. The Rhizobial bacteria occupy nodules on the plant roots. Most legume seed comes with bacterial inoculant in the form of a fine powder. Usually this inoculum is already dead or is not the right species for the native legume and the majority of the nodulation that actually occurs is from Rhizobia already present in the soil.. Extremely disturbed soils may contain no Rhizobia at all. More information on Rhizobia is available at the University of Minnesota website: http://www.rhizobium.umn.edu/. Another form of inoculum that is available are various mycorrhizal fungi. Most mycorrhizal inoculants that are available are ecto- mycorrhizae, which are for woody species. The type of mycorrhizae that associate with prairie species are endo-mycorrhizae, specifically vesicular arbuscular mycorrhizae (VA mycorrhizae). To our knowledge, no good commercial sources for VA mycorrhizae are available at this time for prairie species. Seed Treatments - Be aware that seeds of many native species require specialized treatments. such as cold/moist stratification, scarification, etc. Many of these species go through such treatments naturally if seeded in the fall. Origin Requirements: It is preferred that seed of all native grasses and fortis be "certified" to be of MN (or regional) origin and of wild ecotype, except for fowl bluegrass, slender wheat grass, and fringed brome, which may be of MN, ND, MT or Canadian origin. These species should be available as Minnesota origin in a few years. The origin certification program is administered by the Minnesota Crop Improvement Association (MCIA). Documentation accompanying origin certification should include the "yellow tag" if species are being supplied individually and/or a document from MCIA indicating origin. On labels affixed to bags of seed it is common to show the species, germination, purity, lot number, and under origin "YT" or yellow tag with the geographic origin (i.e., Hennepin Co., MN). Seed Texture and Size Seed texture and size of native seed is highly variable. Some native seed such as Switchgrass is very small while other native seed such as Canada Wildrye has long awns. Mn/DOT Seeding Manua12003 (Page 29) If a drill or drop seeder is used, the seed mixture ingredients should be ordered such that the seed is packaged separately based seed size and texture. Fluffy seed should be placed in the native seed box that contains picker fingers. Fine seed should be placed in the fine seed box. Cereal grains, such as oats and winter wheat, used for a cover crop should be placed in the grain seed box that contains flutes. If a broadcast seeder is used, the seed mixture may either be ordered mixed or as separate ingredients. During installation, the operator should be aware that fluffy seed will have a tendency to bridge or "ball up" in the seeder. Fine seed has a tendency to "pour through" the seeder. Therefore, an effective agitator is required in the seed box. Mixing heavier seed such as sideoats grama, wheat and oats will also help "weigh down" the lighter fluffy seed. If a hydroseeder is used, the seed is usually ordered as a mixture. The hydroseeder has a vigorous agitator in the tank. Seeding Methods Method 1. Drop Seeding Onto Tilled Sites -This is the "standard" method for seeding native species on prepared sites such as those on construction projects. A) Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. B) Fertilizer - If not basing the fertilizer application on soil test results, the fertilizer used should be a commercial grade slow release complete fertilizer applied at a rate of 400 lbs/acre at the time of preparing the seed bed for seeding. The fertilizer should contain 10-10-20 (NPK) analysis, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). C) Seed Installation -Seed should be installed with a drop seeder that will accurately meter the types of seed to be planted and keep all seeds uniformly mixed during planting (Trillion-type). The seeder should contain a minimum of three seed boxes; a fine seed box, a box for large/fluffy seeds, and a box for cool season or grains. It should be equipped with drop tubes and a packer assembly to compact the soil directly over the seed. All seeding should be done at a right angle to surface drainage. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Harrowing -The site should be lightly harrowed or raked following seeding if the seeder does not contain a cultipacker. F) Packing - Cultiacking the site following harrowing is recommended to ensure a firm seed bed. G) Mulch -The site should be mulched and disc-anchored following packing using one of the following types of mulch (as per plans or special provisions): • Mn/DOT Type 3 (MCIA certified weed free mulch) at a rate of 2.0 tons per acre. • Prairie hay/mulch (Mn/DOT Type 7 or 8) at a rate of 2.0 tons per acre. Method 2. Drill Seeding Into Temporary Cover Crops -This method involves two separate seeding operations. First, a temporary cover crop is planted on the entire site to stabilize the soil and control erosion. Second, the native seed mixture is installed the following fall or the next spring (during one of the optimum seeding dates) using either an interseeder type drill or by lightly disking down the temporary cover and seeding into it. The interseed method greatly reduces the erosion potential and reduces soil disturbance. Using this method allows for some early weed control before the native mixture is installed. This method is used for various reasons such as when a site is ready for seeding at Mn/DOT Seeding Manua12003 (Page 30) a time of year that is not optimum for seeding a permanent seed mixture, the soils need to be stabilized rapidly for erosion control, or a field needs to be left fallow due to residual herbicide. I. Establishment of Temporary Cover Crop A) Site Preparation -The new site should be prepared for the. temporary seeding by loosening topsoil to a minimum depth of 3 inches. B) Fertilizer -The fertilizer used should be a commercial grade of slow release complete fertilizer applied at a rate of 2001bs/acre at the time of preparing the seed bed for seeding. The fertilizer should contain 10-10-20 (NPK) analysis, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). C) Seed Installation -Temporary cover crops of oats, winter wheat, ReGreen or combinations of the above may be installed using a standard grain drill or broadcast. Planting depth should be 1/4 to 1/2 inch. D) Seeding Rates -The temporary cover crop of oats or winter wheat should be seeded at a rate of 801bs/acre. If ReGreen is used as a cover crop, it should be installed at a rate of 30 lbs/acre. E) Harrowing -The site should be harrowed or raked following installation of the temporary cover crop. F) Packing -Packing is not required after installing the temporary cover crop. G) Mulch -The site should be mulched and disc-anchored following packing using one of the following types of mulch (as per plans or special provisions): • Mn/DOT Type 3 (MCIA certified weed free mulch) at a rate of 2.0 tons per acre. • Clean grain straw at a rate of 2 tons per acre. • Prairie hay/mulch (1VIn/DOT Type 7 or 8) at a rate of 2.0 tons per acre. II. Establishment of the Native Mixture -The native mixture can be established into the areas previously seeded with a temporary cover crop by one of two methods; 1) interseeding using a no-till drill, or 2) by lightly tilling the area with a disc and seeding using one of the other acceptable seeding methods. Al) Site Preparation for Interseeding - No tillage is necessary for installation of the native seed mixture. The site may require mowing if the temporary cover has grown taller than 12 inches and is still actively growing (winter wheat may require this). This will stop the rapidly growing cover crop from reaching maturity and shading out the establishing native vegetation. Optimal height for existing vegetation to be drilled into is 4-6 inches. No other site preparation is necessary. A2) Site Preparation with. Light Tillage -The area seeded with a temporary cover crop should be prepared by lightly disking to incorporate some of the mulch and temporary cover crop into the soil surface. Approximately 50% of the soil surface should be visible through the mulch or plant debris. Much of the existing cover should be left in place for its mulch value. B) Fertilizer -The fertilizer used should be a commercial grade of slow release complete fertilizer applied at a rate of 2001bs/acre at the time of preparing the seed bed for seeding. The fertilizer should contain 10-10-20 (NPK) analysis, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). The rate is reduced by half the normal recommendation because the initial half of the fertilizer was applied with the cover crop. C1) Seed Installation By Interseeding -The native seed mixture should be installed with a seed drill that will accurately meter the types of seed to be planted and keep all seeds uniformly mixed during the drilling (Truax-type). The drill should contain a minimum of two seed boxes; a fine seed box and a box for large/fluffy seeds, and it should be equipped with disc furrow openers and packer assembly to compact the soil directly over the drill rows. Maximum row Mn/DOT Seeding Manual 2003 (Page 31) spacing should be 8 inches. The inter-seeder drill must be out-fitted with trash rippers which will slice through the vegetative mat and make a furrow into the underlying soil approximately 1 inch wide by 1/2 to 1 inch deep. These furrows shall be directly in line with the drill seed disc openers. Fine seed can be drop-seeded onto the ground surface from the fine seed box, and large/fluffy seed should be placed to obtain a final planting depth of 1/4 to 1/2 inch. All drill seeding should be done at a right angle to surface drainage. C2) Seed Installation By Drilling Lightly Tilled Sites -The native mixture should be installed with a seed drill that will accurately meter the types of seed to be planted and keep all seeds uniformly mixed during the drilling (Truax-type). The drill should contain a minimum of two seed boxes; a fine seed box and a box for large/fluffy seeds, and it should be equipped with disc furrow openers and packer assembly to compact the soil directly over the drill rows. Maximum row spacing should be 8 inches. Fine seed should be drop-seeded onto the ground surface from the fine seed box, and large/fluffy seed should be placed to obtain a final planting depth of 1/4 to 1/2 inch. All drill seeding should be done at a right angle to surface drainage. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. When using the 300 series mixtures, reduce the cover crop component from 70 lbs/acre to 35 lbs/acre. E) Harrowing -Harrowing is not necessary when seeding the native mixture. F) Packing -Packing the site is recommended to ensure a firm seed bed. G) Mulch -Mulch may not be required with installation of the native mixture, depending on existing site conditions. The site should be mulched to achieve 90% ground coverage (10% bare ground). If this condition already exists mulch is not required. Method 3. Drill Seeding Into Existing Vegetation -This method entails killing the existing vegetation with herbicide and using an interseeder drill to install the seed. A) Site Preparation -The site should be prepared by mowing existing vegetation to a height of 4-6 inches in late April/early May or in late August/early September. The grass should be allowed to re-grow or "flush" before herbicide application with glyphosate, this may take 1-3 weeks depending on weather conditions. Addition of a surfactant and/or addition of 2,4-D to the mix often results in a more complete kill, especially with unwanted broad-leaved species. Recommended herbicide rates are 2.0 quarts/acre of glyphosate and 1.0 - 2.0 quarts/acre 2,4-D. Fall site preparation to control smooth brome grass may require higher glyphosate rates. Seeding can be performed 7-10 days after herbicide application. NOTE: Sites that contain significant weed infestations may require other types of weed control during preparation to ensure that the planting is a success. B) Fertilizer -Fertilizer is generally not required when using this seeding method. C) Seed Installation -The native seed mixture should be installed with a seed drill that will accurately meter the types of seed to be planted and keep all seeds uniformly mixed during the drilling (Truax-type). The drill should contain a minimum of two seed boxes; a fine seed box and a box for large/fluffy seeds, and it should be equipped with disc furrow openers and packer assembly to compact the soil directly over the drill rows. Maximum row spacing should be 8 inches. The inter-seeder drill must be out-fitted with trash rippers which will slice through the vegetative mat and make a furrow into the underlying soil approximately 1 inch wide by 1/2 to 1 inch deep. These furrows shall be directly in line with the drill seed disc openers. Fine seed should be drop-seeded onto the ground surface from the fine seed box, and large/fluffy seed should be placed to obtain a final planting depth of 1/4 to 1/2 inch. All drill seeding should be done at a right angle to surface drainage. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Harrowing -Harrowing is not required when using this seeding method. F) Packing -Packing the site is recommended to ensure a firm seed bed. Mn/DOT Seeding Manual 2003 (Page 32) G) Mulch -Mulch is not required when using this seeding method. Method 4. Broadcast Seeding -Broadcast seeding is performed either with mechanical "cyclone" seeders, by hand seeding or by any other method that scatters seed over the bare soil surface. The most desirable aspect of broadcast seeding is that there is no row effect such as that which results from drill seeding. This lends a more natural appearance to the planting. However, broadcast seeding may not be desirable if the weather is hot and dry and/or the soil moisture is content is low. It is essential that steps be taken to ensure good seed to soil contact when broadcast seeding is used. A) Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. It is critical that the seed bed be loosened to a point that there are spaces for seed to filter into cracks etc., otherwise it may end up on the surface and wash away with the first heavy rain. B) Fertilizer - If used, the fertilizer used should be a commercial grade of slow release complete fertilizer applied at a rate of 4001bs/acre at the time of preparing the seed bed for seeding. The fertilizer should contain 10-10-20 (NPK) analysis, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). C) Seed Installation -Seed should be installed by broadcasting it evenly over the entire site. Several types and sizes of broadcast seeders are available for use, ranging from fertilizer-type spreaders to power spreaders mounted on all terrain vehicles. Seed should be mixed thoroughly prior to seeding and should be mixed occasionally in the spreader to prevent separation and settling. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. E) Harrowing -The site should be harrowed or raked following seeding. F) Packing -The site should be packed using a culti-packer or equivalent following harrowing. G) Mulch -The site should be mulched and disc-anchored following packing using one of the following types of mulch (as per plans or special provisions): • Mn/DOT Type 3 (MCIA certified weed &ee mulch) at a rate of 2.0 tons per acre. • Prairie hay/mulch (Mn/DOT Type 7 or 8) at a rate of 2.0 tons per acre. • Mn/DOT Hydraulic Soil Stabilizer or Bonded Fiber Matrix on inaccessible sites. Method 5. Hydroseeding -Hydroseeding is an acceptable method for establishing natives when it is done correctly. However, it is imperative that the site is prepared and finished properly. Mn/DOT generally uses hydroseeding on steep slopes or other areas inaccessible to a seed drill such as wetland edges and ponds. Hydro-seeding native grasses and fortis is not recommended if the extended weather patterns are hot and dry and the soil surface is dry and dusty. The seed-water mixture should be applied within one hour after the seed is added to the hydro-seeder tank. A) Site Preparation -The site should be prepared by loosening topsoil to a minimum depth of 3 inches. It is critical that the seedbed be loosened to a point that there are a lot of spaces for seed to filter into cracks etc., otherwise it may end up on the surface and wash away with the first heavy rain. B) Fertilizer - If used, the fertilizer used should be a commercial grade of slow release comRlete fertilizer applied at a rate of 400 lbs/acre at the time of preparing the seed bed for seeding. The fertilizer should contain 10-10-20 (NPK) analysis, and should include sulfur and iron as well (not less than 1% and not more than 8% added sulfur and iron). C) Seed Installation -Seed should be installed by hydro-seeding it evenly over the entire site. A fan-type nozzle should be used with approximately 500 gallons of water per acre. It is recommended to add approximately 75 pounds of hydromulch per 500 gallons of water for a visual tracer to ensure uniform coverage. D) Seeding Rates -Rates are specified in the mixture tabulation for the specified mix. Mn/DOT Seeding Manua12003 (Page 33) E) Harrowing -The site should be harrowed or raked following seeding. F) Packing -The site should be packed using a culti-packer or equivalent following harrowing. G) Mulch -The site should be mulched and disc-anchored following packing using one of the following types of mulch (as per plans or special provisions): • Mn/DOT Type 3 (MCIA certified weed free mulch) at a rate of 2.0 tons per acre. • Prairie hay/mulch (Mn/DOT Type 7 or 8) at a rate of 2.0 tons per acre. • Mn/DOT Hydraulic Soil Stabilizer or Bonded Fiber Matrix on inaccessible sites. NOTE: When seeding in conjunction with a hydraulic soil stabilizer (bonded fiber matrixes (BFM's), hydro-mulches, etc., it is recommended that atwo-step operation be used. Seed should be placed first and the hydraulic soil stabilizer be sprayed on afterwards. This is to ensure that seed comes into direct contact with the soil. Mn/DOT Seeding Manua12003 (Page 34) Maintenance Requirements General Seed Mixtures 240, 250 and 280 Year 1 Maintenance after Spring or Early Summer Seeding: 1) Mowing during early Fall may be necessary if weed infestation or shading becomes a problem. 2) Weed Control -mowing should help control annual weeds. Spot spray thistles etc. 3) If plants are growing slowly, you can apply fertilizer (20-10-10 analysis) as necessary over the top to improve growth. Maintenance after Fall or Dormant Seeding: 1) Mowing in May or June may be necessary if weed infestation becomes a problem. 2) Weed Control -mowing should help control annual weeds. Spot spray thistles etc. Long Term Maintenance: 1) Can mow 3 times per year as desired. 2) Spot spray weeds as needed. General Seed Mixtures 260 and 270 Year 1 1) Provide water if necessary to aid establishment 2) After turf grasses reach a height of 6 inches, initially mow to a height of 2 to 3 inches. Long Term 1) Fertilize and water as needed. 2) Mow a minimum of once every 2 weeks. Native Grass and Forb Mixtures (310, 330, 340, 350 and SB through 28B) Year 1 Establishment (spring seeding): 1) Prepare site -Late April -May. 2) Seed -May 1 -July 1. Maintenance: 1) Mow (6-8 inches) -every 30 days after planting until September 30. 2) Weed Control -mowing should help control annual weeds. Spot spray thistles etc. Establishment (fall seeding): 1) Prepare site -Late August -early September. 2) Seed -late September to freeze-up. Maintenance (following season): l) Mow (6-8 inches) -once in May, June and July. 2) Weed Control -mowing should keep annual weeds down. Spot spray thistles etc. Evaluation: 1) Cover crop growing within 2 weeks of planting (except dormant plantings). 2) Seedlings spaced 1-6 inches apart in drill rows. Mn/DOT Seeding Manua12003 (Page 35) 3) Native grass seedlings may only be 4-6 inches tall. 4) If there is a flush of growth from foxtail etc., mow as necessary. Year 2 Maintenance: 1) Mow (6-8 inches) one time between June 1 -August 15 before weeds set seed. 2) Weed Control -mowing should keep annual weeds down. Spot spray thistles etc. 3) Some sites may not require much maintenance the second year. Evaluation: 1) Cover crop will be gone unless winter wheat was used in a fall planting. 2) Grasses forming clumps 1-6 inches apart in drill rows, but still short. 3) Some flowers should be blooming (black-eyed Susans, bergamot etc.). 4) If there is a flush of growth from foxtail etc., mow site. Year 3 Maintenance: 1) Mow only if necessary. 3) Weed Control -Spot spray thistles, etc. 4) Sites usually do not require much maintenance the third year. Evaluation: 1) Planting should begin looking like aprairie -tall grasses, flowers etc. Long-term Maintenance: 1) Weed Control -Spot spray thistles etc. 2) Burning (3-5 year rotation) alternate spring and fall if possible. 3) Haying (3-5 year rotation) late summer or early fall. Alternate with burning (may substitute for burning). 4) Burning two years in a row will really "clean up" rough-looking sites.
