The surface layer is gravelly <br />loam about 4 inches thick. The subsurface is calcareous clay loam about 8 inches thick and <br />the underlying material is calcareous gravelly loam to 26 inches. The soil is over calcareous <br />sandstone at depths from 20 to 40 inches. The soil makes up 70 percent of the complex. <br />Sandstone channery is found throughout the soil. <br />The soil is rated poor as a source of topsoil due to excessive slope. Soil pH is 7.4 to 7.8 in <br />the upper horizons and 7.9 to 8.4 in the underlying material. Conductivity is less than 4 <br />mmhos /cm (at 25 C.). Slope is 25 to 65 percent. <br />6.4.10 EXHIBIT J — Vegetation Information <br />The following information has been taken from the currently approved permit <br />Vegetation Site Name — Loamy Slopes Range Site <br />Potential Plant Community — Soils are moderately deep, stony loams, or light clay loams. <br />Total annual yields are 500 to 1200# /acre.
