Fertilizer and Mulch: Manure can be spread on the prepared surface at <br />the rate of 20 tons per acre; or nitrogen (N) and phosphorus (P2O5) <br />fertilizer can be applied and incorporated at a rate of 40 lbs per <br />acre each. Time of application should be immediately prior to <br />seeding. If nitrogen and phosphorus are applied, a native hay or <br />straw mulch will have to be spread and crimped into the soil at a rate <br />of 4000 lbs per acre after fertilizing. Mulch should be crimped into <br />the soil in such a way that 6 inches of mulch protrudes from the soil <br />surface. These measures will help control wind and water erosion <br />until the grass becomes established. <br />Grass Seeding: Total area to be seeded should include all disturbed <br />areas. The seedbed should be well settled and firm, but not friable, <br />for seed placement. Soils that have been compacted by equipment <br />should be tilled to break up rooting restrictive layers, then <br />harrowed, rolled or packed to prepare the required firm seedbed. <br />Grass should be drilled using a grass drill from November 1st to April <br />30th, prior to a period of anticipated moisture and after all other <br />treatment is completed. Recommended planting depth is 1/4 to 3/4 <br />inches. Species to be seeded should be: <br />Species <br />Alkali sacaton <br />Prairie cordgrass <br />Switchgrass <br />Western wheatgrass <br />Big bluestem <br />Pure live seed/acre <br />------------------- <br />0.375 <br />0.25 <br />0.9 <br />3.2 <br />1.1 <br />(See attached seeding recommendation, CO-ECS-5, Part I) <br />Weed control: Weed control should be accomplished on the site during <br />grass stand establishment. Weed control can be chemical (see chemical <br />dealer for recommendation, application rates, and time of application) <br />or mechanical. Mowing shows best results when completed between mid <br />June and early July. No grazing should be allowed during the first <br />two years of establishment. After this period, the success of the <br />seeding should be evaluated. If a lush stand is present, grazing may <br />begin. If it is determined that an insufficient stand of grass is <br />present, the area should be seeded again. <br />If you have any questions, please call or come by our office. <br />Sincerely, <br />?tit5Y1 0??1?_ <br />Dawn Jackson <br />Resource Conservationist
