' ,SEEDING ANU PLANTING ~~' <br />• ~ <br />~. Seedinga must follow the tillage operations immediately eo tl+at weeds do not <br />become established; and tl+e seeding can take advantage of tl+e normal rains occurring <br />from June 25t1, to August lOtl, to become established. A second planting tame late in <br />October can also be used if tl,e ground temperature ie~near.};reezing to prevent fall <br />germination of plants. I. <br />1'I+e vegetation prior to mining varies on tl+e different soil types. '1'I+e Uerrick <br />very gravelly loam ie dominated by grasses witl+ a few low sl+rubs. 7'I+e most abundant <br />grass is blue grama with taller, cool season species such as bo[tlebrusl+ squirreltall, <br />western wl+eatgraes, Indian ricegrass,.needleandtl+read, sanddropseed and Fendler tl+ree- <br />awn comprising tl:e grass stand. Forba sucl+ as scarlet globemallow, erigonum, seneclo, <br />evening primrose, beggarstick, and lambaquarter ace common. Scattered sl+rubs include <br />tl,readleaf Crean rabbitbrusl~, varieties of rubber rabbitbrusl+, prickly pear, yucca, <br />and occassionally winterfat. Weedy species that will move into disturbed areas are <br />Kocl+ia, Russian tl~ietle, sunflowers, tansy mustard, and pepperweed. <br />Tl+e Space City loamy sand is dominated by the taller cool season grasses witl+ <br />needleandthread, Indian ricegraes, and western wheatgrass with blue grama, sand <br />dropseed, bottlebrusl+ aquirreltail, and Fendler three-awn occurring in scattered <br />clumps. Forba au cli as scu rf pea, sand verbena, senecio, and bee plant occur on tl+e <br />site. Sl+rube include tl,readleaE Green rabbi[brusl,, Bigelow rubbef rabbitbrusl+, two <br />o[I+er varieties of rubber rabbitbrush, prickly pear, and yucca. 1'I+is is a fragile <br />site that will be easily ended by wind and water during mining and reclamation. <br />1'he seed mixture for the Derrick soil at reclamation and while stockpiled sl+all <br />contain tl:e following pure live seeds: <br />Blue grama (Bouteloua gracilis) - Ilacl:ita variety I.1 pounds/acre <br />Indian ricegraes (Oryzopeis I+ymenoides) - Nespar variety 2.5 pounds/acre <br />Needleandthread (Stipa comata) 2.3 pounds/acre <br />lJestern wheatgrass (Agropyron smitl~ii) - Arriba variety 3.2 pounds/acre <br />Sand dropseed (Sporobolus cryptandrus) 0.1 pounds/acre <br />Tl+e seed mixture for tl:e Space City soil at reclamation <br />and while stockpiled shall contain tl~e following pure live <br />seeds: <br />Blue grama (Bouteloua gracilis) - Ilacl+lta variety 0.5 I+ounds/acre <br />Indian ricegraes {Oryzopsis liymenoides) - Nespar variety 5.6 pounds/acre <br />Needleandtl+read (Stipa comata) 2.3 pounds/acre <br />Western w1+eaCgrass (Agropyron smithii) - Arriba variety 2.G pounds/acre <br />' Sand dropaeed'(SporobolUe cryptandrus) 0.1 pounds/acre <br />All seeaings shall be accomplished will: a rangeland grass drill tl+at is equl~+ped <br />will, seed agitators, disk furrow openers and packer wl+eels. 1'I+e seeding will be <br />accomplished in two operations. Tl+e Indian ricegraes and needleandtl+read will be <br />seeded first at a depth of 1!i incl+es to 2 incl+es following tl+is operation tl+e blue <br />grama, western wheatgrass, and sand dropseed will be seeded at a deptl+ not to exceed <br />!S inch with % inch preferred. Inert material such as cracked corn and rice hulls may <br />be used [o carry tl+e seeds througl~ tfie drill. <br />Si+ould a broadcasC seeding method be used over tl+e grass drill tl+e following <br />steps must be initiated: . <br />1) Double the seeding rate. <br />2) harrow or cultipeck tl+e soil• immediately after spreading tl+e seed [o <br />reduce losses of seed to wildlife and erosion. <br />
