• All seed will meet the requirements of the Federal Seed Act (7 U.S.C., Section 1551-1610, incl.) and the seed and noxious weed laws of Colorado. Seed used will be certified and, where possible, will have a minimum purity of 95 percent, minimum germination rate of 85 percent, and maximum weed content of 0.5 percent. Seed genotypically adapted to the area will be utilized when available in sufficient quantity and quality. Broadcast seeding will typically be used, except on gentle slopes of soil stockpiles which may be drill seeded. Mulch will be added as appropriate. Introduced or exotic species occur in both seed mixes to ensure a cool season component and take advantage of the early spring moisture common in southern Colorado in most years. These species are very palatable to livestock and wildlife and add diversity to a dominant blue grama mosaic. Rill and Gully Plan Prior to using machinery to alleviate an erosion problem, all other reasonable alternatives to grading will be employed to allow stabilization. If such action becomes necessary, a small rubber- tired farm vehicle, like arubber-tired dozer, utilized for reclamation will be allowed on the site to regrade the gully. Once a site is regraded, it will immediately be planted to the appropriate perennial seed mixture. • Seeding Methods Drill seeding will be utilized on the majority of the area. This technique results in proper depth placement of seed and promotes good contact between seed and soil. Drill seeding will be done along the contour wherever the surface is not level. Broadcast seeding will be employed on rocky areas, on steeper slopes, and on small disturbances. Seed will be broadcast using a manually operated cyclone-type bucket spreader, a mechanical blower, or hydroseeder. Seed will be frequently mixed to discourage settling. Where possible, broadcast seeded areas will be chained, harrowed, or culti-packed to cover the seed. Where slope conditions allow, broadcast seeded areas will be dozer-tracked perpendicular to the slope. On small, isolated, or inaccessible sites, hand raking will be utilized to cover seed and assure good soil to seed contact. When hydroseeding is used, seed, fertilizer, and mulch at a rate of approximately 250 pounds/acre will be sprayed in one application. Where hydromulching is used, a second application will spray additional mulch and a tackifier at the manufacturer's recommended application rate. • PERMff ,.~~nP~~~:s. i~ 2.05-69 (revised 4/21/97)
