Grading and Erosion Control per Civil Plans and Specifications.Add 20lbs per acre of MnDOT 21-111 Oats Cover Crop.MNDOT SEED MIXES:NATIVE SEEDING INSTALLATION METHOD:Drop Seeding Onto Tilled SitesThis 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 3inches.b)Fertilizer: Use a fertilizer analysis based on a soil test or a general recommendation is a10-10-10 (NPK) commercial grade analysis at 200 lbs/acre.c)Seed Installation: Seed should be installed with a drop seeder that will accurately meter thetypes of seed to be planted, keep all seeds uniformly mixed during the seeding and containdrop seed tubes for seed placement (Brillion-type). The drop seeder should be equipped with acultipacker 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 cultipackedfollowing the seeding to ensure seed-to-soil contact.f)Mulch: Cover soil with a hydromulch consisting of natural wood fiber or paper fiber, water, andM-Binder at 100 lbs per acre.Note: Heavy equipment is not allowed in the infiltration basins to keep soils from getting compacted.If any compaction occurs due to seeding operations, the soils must be uncompacted.NATIVE SEED REQUIRED MAINTENANCE - 3 YRS:Native Grass and Forb Mixtures (mixtures beginning with the number 3)Year 1Establishment (spring seeding):1)Prepare site - Late April - May2)Seed - May 1 - June 1Maintenance: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 September2)Seed - late September to freeze-upMaintenance (following season):1)Mow (6-8 inches) - once in May, June, and July2)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.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 2Maintenance: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 3Maintenance:1)Mow only if necessary.2)Weed Control - Spot spray thistles, etc.3)Sites usually do not require much maintenance the third year.Evaluation:1)Planting should begin looking like a prairie - tall grasses, flowers, etc.Long-termMaintenance: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.MNDOT Seed Type 'B' areas noted per plan: (unless otherwise noted on civil plans), shall be:MnDOT Wet Ditch seed mixture, drilled into the topsoil layer at 20.0 lbs per acre.
