SOILS INFORMATION <br /> the nitrogen content declines and as it declines more of the perennial species tend to invade. But this <br /> is a very long process that proceeds at an almost imperceptible pace. <br /> It is likely that when these soils are salvaged and redistributed, heavy weed growth will be a <br /> serious problem. Two methods can be used to help control this problem. First, and most obvious, is to <br /> not let the weeds reseed themselves. That can be accomplished with mowing or with herbicides. <br /> The other method is to load the replaced topsoil with high carbon materials. When the high <br /> carbon material is attacked by bacteria the nitrogen in the soil will largely be consumed in the <br /> decomposition process resulting in a soil that has a much lower nitrogen component that will be more <br /> favorable to perennial grasses and less favorable to weeds. However,weed control with mowing <br /> and/or herbicides will probably still be needed due to the very rich soil and high quantity of weed seed <br /> already in the soil. <br /> But if the weed growth is managed this soil should produce some very rich growth of native or <br /> introduced grasses. Care should be exercised though to not place the soil on steep slopes (steeper than <br /> about 4:1) as the clay and silt content may hold large amounts of water during wet periods. If that <br /> occurred, slope failure in the form of slumpage could easily occur. But on more gradual slopes, <br /> slumpage should not be a problem, although rill and gully erosion may still be a problem. If a strong <br /> vegetation cover can be established quickly that should not be as severe a problem, but some rill and <br /> gully erosion in this material should still be expected and controlled promptly. <br /> Daniels Sand Pit#2 Amendment (2008) Exhibit I Page 8 of 8 <br />
