during operations. These latter lands occur in the south and north portion of the proposed permit <br />expansion area. <br />Topsoil replacement operations may be carried out during most of the year, the exception being <br />those periods when wet conditions would preclude handling of the topsoil materials. Prior to <br />replacement of topsoil, the graded spoil will be ripped to reduce compaction. Detailed topsoil <br />handling and replacement plans are provided in Section 2.05.4(2)(d), Topsoil (Redistribution). The <br />optimum seeding season for establishment of irrigated pasture is during the spring as early as soi! <br />moisture conditions allow for tillage and seeding operations. As a result of irrigation, seeding may <br />be carried out as late as July 15. This will allow fora 75-90 day growing season, enough time to <br />establish an adequate stand capable of over-wintering. Fall dormant seedings may be made into <br />annual grain stubble if the potential for competition from established weedy species is not great. <br />For situations where temporary stabilization is required outside of the normal seeding periods, and <br />the stabilization period is less than one year, an annual grain cover crop of barley or winter wheat <br />will be used, Seed Mix #2. At times, the size or shape of the retopsoiled areas and shape of the <br />reclaimed area in relation to a management unit may be insufficient to warrant establishment of the <br />perennial irrigated pasture species initially. When this occurs, and the period before establishment <br />of permanent irrigated pasture will extend beyond a year, Seed Mix #3 -Temporary Reclamation, <br />will be used. This mix will provide interim stabilization as well as organic matter benefits when <br />incorporated during tillage and seedbed preparation prior to seeding of the irrigated pasture seed <br />mixes. <br />Prior to final seedbed preparation, soil conditioning and weed control tillage will be carried out <br />through the use of chisel plowing and disking. Chisel plowing will relieve any topsoil compaction, <br />will aid in controlling weedy species, and will leave the site in a temporary toughened condition <br />reducing wind and water erosion potential. Disking will be used to condition soil, break up clods, <br />and control weeds through tillage prior to seeding. If annual weeds are a problem, several tillage <br />operations may be required to get adequate control. Harrowing and cultipacking prior to seeding <br />will be conducted as needed in order to provide the smooth, firm seedbed required. In any areas <br />that maybe poorly drained, tillage will be timed in order to reduce bogging, excessive compaction <br />and excessive cloddiness caused by tillage when soils are wet. The best period for tillage in these <br />areas may be in the early spring prior to the irrigation season (prior to mid-April). Section <br />2.05.4(2)(d), Topsoil (Redistribution), contains additional information on subsoil and topsoil <br />conditioning. <br />(Revised 1-15-03) 2.05.4(2)(e)-3 <br />
