Seed will be planted with a grass drill on all slopes of 33 percent(3:1) or flatter. The grass drill will be equipped with double coulter disc furrow openers, depth bands, and press wheels. The distance between drill rows shall not exceed 7-12 inches. Seed will be planted uniformly and at a depth of 1/4 inch to 1/4 inch. (1)(c)(iii) The following seed mixture has been used on recommendation from the local United States Department of Agriculture Natural Resource Conservation District (NRCS) office: Species Variety PLS/Acre Western Wheatgrass Arriba 16 Little Bluestein Cimarron, Pastura 7 Blue Grama Hachita, Lovington 3 Sideoats Grama El Reno,Niner, Vaughn, 9 Yellow Sweetclover N/A 7 The existing species composition can be summed up with this description from the NRCS office, "This plant community evolved with repeated continuous grazing and occurs frequently throughout most of the eastern plains of Colorado. Fourwing saltbush, winterfat, American vetch and green needlegrass have been removed. Western wheatgrass may persist in minor trace amounts, greatly reduced in vigor and not readily seen. Blue grama and buffalograss dominate the community with a tight sodbound structure. Plains pricklypear, hairy goldaster, red threeawn, sixweeks fescue and bottlebrush squirreltail have increased." (1)(c)(iv) Seed will be broadcast by hand or by mechanical spreader on areas that are small, too steep, or not accessible for seed-drill operations. Seed planted by the broadcast method shall be incorporated into the surface soil, not to exceed a depth of 1/4 inch, by raking, harrowing or other proven method. Seeding rates will be doubled when the seed is broadcast rather than drilled. (1)(c)(v) All areas will be mulched unless a cover crop is planted. Planted areas will be mulched with straw at a rate of 4000 pounds per acre. At least 50% of the mulch by weight shall be 10 inches or more in length. The straw will be free of noxious weeds. The straw mulch will be crimped into the soil with a mulch crimper or with a disc plow. A disc plow can be used by setting the disc straight and applying adequate weight to crimp the straw 4 inches into the soil. Feedlot or barnyard manure may be used in lieu of straw mulch. The manure must be of a type that has 60%or more, by weight, and heavy chunks 5 inches or more in diameter. The minimum rate of application will be 20 tons per acre spread uniformly over the area. Mulching material shall be applied immediately before or after seeding. When stabilizing sandy soils it will be done just prior to seeding to avoid seeding too deep. (1)(c)(vi) No establishment methods using trees and/or shrubs will be used.
