<br />• <br />Reclamation Plan <br />Cortner Feedlot-Pit Ill <br />This is in reference to an on-site investigation done December 3 <br />a proposed gravel mine located in the NEB of the NE~y of section <br />R64W. The following information may be used by your company to <br />the requirements of [he Colorado Mined Land Reclamation Board. <br />1986 on <br />4 T21S <br />The post-mining use is livestock grazing. The site is not prime farmland. <br />The owner of the land is Mr. Cortner. Ne will be responsible fo the <br />reclamation. <br />The Cascajo soils support a plant community that is dominated by blue grama <br />with amounts of sand dropseed, sideoats grama, galleta and scatt red forbs <br />and shrubs. See the attached CO-ECS-2 for a more detailed estim to of <br />plant cover and percent composition. The Soil Conservation Serv ce recom- <br />mends the following steps to revegetate the site: <br />1) The site has a very cobbly topsoil. Six inches of the top 1 <br />be removed and stockpiled. <br />2) After mining is complete and prior to spreading the topsoil, <br />should be banksloped so that no slope exceeds a 3:1 slope. Roug <br />be smoothed [o permit easier seeding and mulching. The area sho <br />scarified, to a depth of 6 inches to permit better bonding betwe~ <br />soil and the underlying soil material. After scarification, the <br />should be uniformly spread over the area. <br />3) A soil test should be performed to determine the proper Pert <br />quirement. In lieu of a soil test, fertilize the entire area wi <br />pounds per acre each of available elemental nitrogen (N) and pho <br />acid (PZOS). The ferilizer must be incorporated into the top 2 <br />of soil using a disk or harrow implement. Fertilizer should be <br />immediately prior to seeding, or at the time of seeding. See It <br />using manure as a fertilizer. <br />4) Soils that have been overcompacted by traffic or equipment s <br />tilled to break up rooting restrictive layers, harrowed and then <br />or packed to prepare the required firm seedbed. The seedbed sho <br />settled and Eirm, but friable enough that seed can be placed at <br />mended seeding depth. The ideal firmness is when a one-half inc <br />print remains after walking across the soil surface. <br />Species Variety MixY, Lbs. <br />sideoats grama Vaughn or Niner 50 4.' <br />blue grama Covington or Hachi[a 30 0.' <br />sand dropseed - 10 0. <br />switchgrass Grenville 10 0.. <br />should <br />the area <br />areas should <br />ld be <br />n the top- <br />zer re- <br />40 <br />oric <br />3 inches <br />lied <br />7 for <br />ould be <br />rolled <br />ld be well <br />he recom- <br />boot <br /> <br />
