<br />5) Mulching the soil surface to retain moisture. Use a <br />good quality hay or straw mulch free of noxious weeds for <br />this operation. The mulch material should be evenly spread <br />at a rate of 1500 to 2000 pounds per acre. The mulch must be <br />anchored with a studded roller or straw crimper. <br />The tillage operations will release soil moisture <br />(approximately 2 inches of evaporation loss per operation) <br />if the soil material is moist. These operations should be <br />completed in early June or in early October immediately <br />ahead of planting. All operations must be completed timely <br />so as not to delay planting. <br />Optional Operations may include: <br />1) Pitting or land imprinting to create an irregular <br />surface. <br />2) Fertilizing with 20 to 40 units of nitrogen per <br />acre. Base all fertilizer applications on current soil test <br />at the time of reclamation. <br />SEEDINGS <br />Seedings must follow the tillage practices immediately to <br />minimize the establishment of weeds. Seeding in late June <br />will take advantage of the normal summer rains in July and <br />August. A second planting time in late October can be used <br />if the ground temperature is near freezing to prevent fall <br />germination. <br />The recommended seed mixture is intended to return the site <br />to a vegetative composition which is similar to the native <br />vegetation. <br />The seed mixture for reclamation of the site and to <br />stabilize the stockpiles shall contain the following pure <br />live seeds: <br />Blue grams (Bouteloua gracilis) Hachita variety, 1.2 <br />pounds/acre <br />Western wheatgrass (Agropyron smithii) Arriba or Barton <br />variety, 3.2 pounds/acre <br />Indian ricegrass (Oryzopis hymenoides) Nezpar variety, <br />2.5 pounds/acre <br />Sand dropseed <Sporobolus cryptandrus) .1 pound/acre <br />Fourwing saltbush <Atriplex canescens) Rincon variety, <br />.5 pounds/acre <br />Winterfat (Eurotia lanata or Certoides lanata) .5 <br />pounds/acre <br />All seedings shall be accomplished with a rangeland grass <br />drill that is equipped with seed agitators, disk furrow <br />openers, and packer wheels. The seeding should be <br />accomplished in two operations. The Indian ricegrass should <br />
