<br />Fertilizer: Manure can be spread on the prepared surface at the <br />rate of 30 tons per acre; or nitrogen (N) and phosphorus (P205) <br />fertilizer can be applied and incorporated at a rate of 40 lbs <br />per acre each. Time of application should be immediately prior <br />to seeding. If nitrogen and phosphorus are applied, a native hay <br />or straw mulch will have to be spread and crimped into the soil <br />at a rate of 4000 lbs per acre after fertilizing. Mulch should <br />stick 6" out of the soil. These measures will help control wind <br />and water erosion until grass become established. <br />Grass Seeding: The seedbed should be well settled and firm but <br />friable for seed placement. Soils that have been over-compacted <br />by equipment should be tilled to break up rooting restrictive <br />layers, then harrowed, rolled or packed to prepare the required <br />firm seedbed. Grass should be drilled using a grass drill from <br />November 1 - April 30 prior to a period of anticipated moisture <br />and after all other treatment is completed. Recommended planting <br />depth is 1/2" to 3/4". Species to be used should be: <br />variety <br />Vaughn <br />Arriba <br />Cimmarron <br />Blackwell <br />Covington <br />Goshen <br />Species <br />sideoats grams <br />western wheatgrass <br />little bluestem <br />switchgrass <br />blue grams <br />prairie sandreed <br />Pure live seed/acre <br />3.15 <br />3.20 <br />1.40 <br />.45 <br />.30 <br />.325 <br />(see attached seeding recommendation, CO-ECS-S, Part I) <br />Weed control should be maintained on the site during grass <br />establishment. No grazing should be allowed until there is a <br />lush stand and none before at least two growing seasons. Total <br />area to be seeded should include all disturbed areas. <br />At the end of two years the success of the seeding should be <br />evaluated. If it is determined that an insufficient stand of <br />grass is present the area should be seeded again.
