32 <br />DISQJS.SIONT <br />Reclamation Practices <br />Vegetation is the most opt-effective form of erosion control. It is <br />generally self~ustaining and aesthetically acceptable. Vegetation can prevent <br />erosion and is therefore a more desirable control measure than corrective <br />1 measures such as straw bale dilcPS, silt fences, axd sediimnt traps and basins. <br />Oorrective devices only trap sed?~*+} after the soil has already eroded. Thus, <br />additional time and oust may be required for oorractive ~~+,*+~ mai*+}~*+~*~-~, and <br />retreating areas with soil erosion. <br />r ^-t= that are rhizomatous are the most effective type of plants for <br />erosion corstx+ol in most areas. Grasses germinate and grow quickly and provide a <br />o~q~lete grand cover. Once a site is stabilized with grass, other species, such <br />as native shrubs may invade the site. <br />Clnrent reclamation practices for the Hourg Mine are to rip the soil <br />surface, drill ~~~ and forts atd broadcast seed shrubs (Table 14). Soils are <br />fertilized with nitrogen and phosphorus (see Reclamation Soils) and Ached at 2 <br />tons of hay per acre. <br />Reclamation Soils <br />'Ilia soil survey did not specifically identify or map a*+~G of saline soil, <br />however saline soils have been enoountesed in the mine permit area. ~ese saline <br />soils have been buried in the pit. It is improbable that saline soils will be <br />enca.IDtered in topsoil spreading frtien the topsoil stockpiles. <br />Soil samples frc~ the reclamation area and topsoil stockpile have been <br />assessed for nutrient availability. Nitrogen and phosphorus additions of 20 and <br />30 pounds (as P20g) per acre have been reo~sded to prt®ote grass establis-,me„* <br />and growth.
