UNITED STATES DEPARTMENT OF AGRICULTURE <br />• SOIL CONSERVATION SERVICE <br />6th & Albert Streets, Walsenburg, Colorado 81089 <br />February 15, 1980 <br />Mr. Charles McNeil <br />;e Perms Resources Corp. <br />105 E. gioxa Suite 200 <br />Colorado Springs, Colorado 80903 <br />Please be advised that there ie no prime farmlands involved in the area <br />you propose to strip mine in Huerfano County. None of this lend qualifies <br />- as unique land either. The reason that some of the better soils involved <br />do not meet the requirements for prime farmland is that there is no <br />irrigation xater available and natural precipitation ie too limited. <br />Your question in regards to flood irrigation of the area is best anaxered <br />by no, idhen xater for irrigation could be diverted out of the arroyos it <br />has generally already rained and the seeded grasses xould not require any <br />more, In this area the feasibility of an irrigation project based on the <br />dry arroyos is very questionable. Obtaining a permit or approval of the <br />State Engineer to do that is doubtful. <br />• <br />Seeding, Recommendations <br />Fertilizer - Minimum 40 lbs. available nitrogen and 40 lbs. available <br />P2o5 per acre. This is best based on laboratory analysis <br />dust prior to seeding. <br />Mulch - M;n;nn,m of 4000 lba, per acre of native grfi99 hay that is <br />not moldy, or rotten and is rather long leafed, approxinatelp <br />8", If grass hay is not available small grain atrax may be <br />used. The mulch material should be anchored xith a dick type <br />implement. <br />Seed Recommendations - Double rates of seed is broadcast. <br />Sandy Soils lbs.
