' INTRAOEPARTMENT MEMO. <br />OOH FORM NO. 37 <br />(30000) 03 <br />' Rev. Aug., 1878 <br />STATE OF COLORADO <br />STATE DEPARTMENT OF HIGHWAYS <br />DIVISION OF HIGHWAYS <br />' GRAND JUNCTION, COLORADO 81501 <br />TO: R.G. Lucas <br />FROM: J.J. Lance <br />RE: Seeding Mixture/Reclamation Guidelines for Myrin Pit near Toponas <br />DATE: August 10, 1979 <br />1 <br />After reading through the SCS information supplied, I have developed the <br />following seed mixture. This mixture is an adaptation of our District 3 <br />Seeding Manual mixture for Zone 3. <br />' The following is a sequential list of steps to follow in the reclamation <br />process. <br />1) Establish pit limits and allow room for topsoil that is stripped <br />' off the surface to be stockpiled. <br />2) Flatten slopes, bury oversized material or remove it from the site. <br />3) The surface of the subsoil material should 6e left in a roughened <br />condition to allow topsoil to bind together with it. <br />4) Topsoil shall 6e redistributed in a uniform depth. The site should <br />then be worked with an implement such as a disk or spring-tooth <br />harrow to a depth of (4-6") four to six inches. This is the time <br />to distribute the fertilizer so that it may be worked into the soil. <br />5) Fertilizer such as Mmonium phosphate sulphate (16-20-0) applied at <br />' a rate of 300 LBS per acre wilt provide sufficient nutrient. This <br />material should be applied just prior to seeding and worked into soil. <br />•' 6) Seed bed should be firm but not packed. <br />7) Drill seed or if broadcast double the rate and use a harrow or drag <br />chains to cover seed approximately ~ to 3/4 of an inch deep. <br />8) Mulch either with 1~ tons/ac of native grasshay or 2 tons of clean straw <br />that is of sufficient length to be crimped into the soil. <br />' 9) Protect area from people, livestock, and vehicles until seedlings are <br />established. <br /> <br />
