<br />Recommendations for Soil Salvage <br />The Nihill channery loam, 1 to 6 percent slopes, in the alfalfa <br />and grass meadows can be salvaged to 12 inches. The surface 12 <br />inches should be good material. Below that depth the soil is too <br />channery for use. <br />The surface Nihill channery loam, 5 to 25 percent slopes, is <br />thinner and can be salvaged from 6 to 12 inches. Below that depth <br />it is too channery for use. <br />The Detra channery loam, 6 to 25 percent slopes, has a thick dark <br />surface layer that can be salvaged to 16 to 24 inches. Below that <br />depth it is stony and low in organic matter. <br />The alluvial land, wet, is not recommended for soil salvage. It <br />is too cobbly and stony and subject to flooding. Disturbance <br />adjacent to the creek should be minimized. <br />The disturbed land is not recommended for topsoil salvage. The <br />soils have been mixed or buried. <br />Erosion Hazard <br />The Nihill channery loam, 1 to 6 percent, is an erosive soil <br />because it is loose and contains high percentages of very fine <br />sand and silt. <br />The Nihill channery loam, 6 to 25 percent slopes, is also erosive, <br />and its toeslope position exposes it to high runoff. <br />The Detra channery loam, 6 to 25 percent slopes, is close to the <br />creeks. The Detra is a good source of topsoil and should be <br />salvaged, but care should be taken to avoid sediment delivery into <br />the creeks. <br />The Torrifluvents adjacent to the creek are subject to erosion <br />during high flows and disturbance should be minimized. <br />The disturbed lands are also highly erosive due to lack of surface <br />cover. <br />9 <br />
