HCWCD REVEGETATION PLAN: PAGE 3 <br /> Step 3 - The seedbed should be well settled and firm, but friable enough so <br /> that seed can be placed at the recommended seeding depth. The ideal <br /> firmness is when a one-half inch boot print remains after walking across the <br /> soil surface. <br /> If the topsoil is over-compacted by traffic or equipment, three steps are <br /> required to prepare the seedbed. First, the soil should be tilled to break up <br /> root restricting layers. Second, it should be harrowed. Third, the soil should <br /> be rolled or packed. These steps establish the necessary firm seedbed. <br /> Step 4 - A soil test should be performed to determine the proper fertilizer <br /> requirement. In lieu of a soil test, fertilize the entire area with forty pounds <br /> per acre of each of available elemental nitrogen (N) and phosphoric acid <br /> (P205). The fertilizer must be incorporated into the top two or three inches <br /> of soil using a disk or harrow implement. Fertilizer should be applied either <br /> immediately prior to or at the time of seeding. <br /> Step 5 - The following seeding mix is adapted to the site. It will serve the <br /> post-mining use and will provide adequate soil protection. These species will <br /> tolerate natural conditions and will survive without irrigation after they are <br /> fully established. <br /> Species Variety Mix % Pounds/Acre* <br /> sideoats grama Butte or Vaughn 20 1.8 <br /> western wheatgrass Arriba or Barton 20 3.2 <br /> switchgrass Blackwell 10 0.4 <br /> little bluestem Pastura 10 0.7 <br /> blue grama Lovington or Hachita 10 0.3 <br /> sand dropseed varietals not avail. 10 0.05 <br /> Indian rice grass Nezpar,Paloma 10 0.8 <br /> Rimrock <br /> Green needle grass Loderm 10 1.0 <br /> * seeding rates are given in pounds of Pure Live Seed (PLS**) <br /> **PLS = purity x germination <br /> 037 <br />
