The purpose of the investigation <br />a reclamation plan for the site to protect the topsoil. <br />located near the intersection of Sections 32, 33, 4, ani <br />215, R64W of Pueblo County. <br />r 15, 1992 on <br />'as to develop <br />The site is :j <br />5, T20 8 -a <br />, <br />The soil maps indicate this site is a Las Animas Fine s ndy loam. On <br />site we determined the soil ter.ture to be a clay loam. The <br />vegetation on the site is predominantly annual weeds, p imarily <br />kochia. <br />The Soil Conservation Service recommends the following Steps to <br />revegetate the site. <br />1) The area should be banksloped so tkjat no slope exce ds a 3:1 <br />elope. Rough areas should be smoothed to permit easier seeding and <br />mulching. <br />2) A soil test should be performed to determine the pr <br />fertilizer requirement. In lieu of a soil test, fertil <br />area with 40 pounds per acre each of available elements <br />and phosphoric acid (P205>. The fertilizer must be inc <br />the top 2 or 3 inches of soil using a disk or harrow in <br />Fertilizer should be applied immediately prior to seedi <br />time of Beading.

The ideal fir ness is when <br />a one-half inch boot print remains after walking across the soil <br />surface. <br />The following seed mix is adapted to the site and will provide <br />adequate ground cover protection: <br />Species <br />Variety <br />% in <br />Mix <br />western wheatgrass Arriba, Barton 40 <br />Qideoats grams Niner, Vaughn 30 <br />blue grams Hachita, Covington 20 <br />sand dropseed 10 <br />~s PLS/ <br />:re• <br />6.4 <br />2.7 <br />0.6 <br />0.1 <br />E <br />+< <br />*seeding rates are given in pounds of Pure Live Seed (1~L5> <br />PLS purity x germination <br />
