Switchgrass (Blackwell) 0.5 #PLS/ac 5 <br /> Totals 9.65 #PLS/ac 100 <br /> Application rate is for drilling the seed. If seed is to be broadcast, the application <br /> rate will be doubled. <br /> The seed mix for final reclamation as described above does not require fertilizer as <br /> recommended by the local NRCS office in Greeley, Colorado. The seeded areas will be covered <br /> with dead crop litter from sorghum or milo crop forage, or with straw mulch at a rate of 4,000 <br /> pounds per acre. <br /> If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before <br /> they can go to seed. The areas will be mowed periodically for additional control as needed. <br /> Mechanical control will be used as a first priority. Chemical methods will only be used if no other <br /> alternative produces acceptable results. <br /> For temporary stockpiles, the reclamation plan includes re-vegetating with appropriate seed <br /> mixes to minimize erosion and establish more rapidly to stabilize the stockpiles. The grass <br /> mixture below was selected as recommended by the Greeley NRCS field office. The proposed <br /> seed mix is shown in the following table. <br /> Temporary Stockpile Seed Mix Application Rate' % in mix <br /> (#PLS/acre) <br /> Slender wheatgrass 3.4 #PLS/ac 44.5 <br /> Pubescent wheatgrass 4.2#PLS/ac 55 <br /> Sand dropseed 0.03#PLS/ac 0.5 <br /> Totals 7.63 #PLS/ac 100 <br /> *Application rate is for drilling the seed.
