<br /> <br />In any event, once mining activity is crn~lete, the ground should be shaped so <br />that no slopes exceed 5:1. Following this, topsoil should be replaced to a depth of <br />at least 6 inches. If there is not enough topsoil at the site then more will have to <br />be brought in to make up the difference. <br />Prior to seeding it is important that the ground be clean tilled and well prepared <br />for drilling. If the seeding is done immediately after replacement of topsoil then <br />little, if any, seedbed preparation will be needed. If, however, seeding is postponed <br />for a period of time and the ground crusts over or weeds become established it will be <br />necessary to disk once or twice to break up the surface crust and remove any weed <br />cong~etition. At this time, nitrogen and phosphorus fertilizer should be applied at the <br />rate of 50 lbs/ac each (net application) <br />The following seeding reeamiendation is based on several factors: 1)It is assumed <br />that the reclaimed area will revert back to it's previous use of livestock grazing <br />land, 2)Those species either currently growing on the site or that have the best <br />potential for growing on the site and which are most easily established and readily <br />available will be selected, and 3)Forb and shrub species that are normally found on the <br />site will not be included in the seeding recannendation as they do not have the erosion <br />control qualities of grass, they are more difficult to establish, they are ~re expensive <br />and, considering the limited size of the reclaimed area, will most likely became well <br />established on their own within a relatively short time span. <br />Species recorm~ended to revegetate this area along with variety, percent of mixture <br />and total pounds PIS are as follows: <br />SPDCIES VARIEPY P13tCENT POUNDS PLS* <br />Western Wheat Arriba 50 8.0/ac. <br />Arizona fescue Redondo 30 1.4/ac. <br />Blue grams Covington 20 0.6/ac. <br /> 10.0 lbs/ac. PIS <br />*PLS=Pure Live Seed: Determined by multiplying percent purity X percent ge*+n~~ation. In <br />order to equal SO lbs/ac PIS, 12 to 15 pounds of bulk seed quantity will most likely <br />have to be planted. ee sure to specify pounds PIS when purchasing seed mixture. <br />Seeding should be done at one of the following times. In the fall after the first <br />heavy frost when the ground is sufficiently cold enough to prevent any germination <br />before the next spring, probably after Oct. 15th. In the spring prior to expected <br />more <br />
