SOIL <br />Chemically, this soil tends to be alkaline and can exhibit moderate <br />salinity in deeper layers. However, there is nothing in the soil description <br />that would indicate the tap 4 to 8 inches could not be saved. It would be <br />best, however, to avoid blending a great deal of the AC horizon with the Al <br />horizon. Therefore, salvage to a maximum depth of about 6 inches would <br />produce a fair growth medium. However, it should be Hated that little of this <br />soil will be disturbed because it is below the gravel layer. C~nerally, <br />processing sites and access roads will be the only disturbances. <br />• <br />MAM/E7_ SILT LOAM. 1% TO S/. SLOPE: <br />The description of the Manuel silt loam, OY. to 1% slopes largely applies <br />to this soil as well. The only difference is that as a result of slightly <br />steeper slopes this soil does Hat exhibit quite as much development as the <br />soil on nearly level ground. For all practical purposes there is no need to <br />differentiate between the two soils in the salvage process. <br />BACA SILT CLAY LOW'I• <br />On this site this soil is only found in one long finger of soil that <br />extends down a valley well below, in elevation, the gravel bed. Therefore, <br />for the purposes of this permit, this soil is of little importance and <br />descriptions will be cursory. <br />Structurally, the soil is well developed exhibiting all three horizons <br />and several sub-horizons. The soil is deep, well-drained, and exhibits a <br />silty texture throughout. Its available water capacity is about the same as <br />for the Manuel. The soil is only fair as a source of topsoil. This is mainly <br />because of the usually high clay content. This soil erodes slowly. <br />For the purposes of this permit, if a mine access road is built across <br />an area occupied by this soil, it is recommended the tap 4 to 6 inches be <br />stripped and stored beside the road, probably in windrows. Then when the road <br />is no longer needed, the surface of the roadway should be intensely ripped and <br />the soil pushed back over the roadway. The roadway could then be revegetated. <br />STOPEFKVM LOAM• <br />This soil is 1«ated uniquely on this site. It only occurs in one <br />fairly large area that is completely surrounded by Cascajo soil. The <br />interesting feature of this soil is it «curs on tap of the gravel deposit and <br />Page 27 <br />
