• Typically the surface layer is a dark gray fine sandy loam about 3 inches thick. The <br />substratum is calcareous and stratified with colors of gray, light brownish gray, and pale <br />brown. Textures are fine sandy loam, loam, sandy clay loam, silt loam, and silty clay loam. <br />Mottling may occur below 40 inches. <br />Permeability is moderate. The available water capacity is high. Effective rooting depth of 60 <br />inches or more.Surface runoff is slow, and the erosion hazard is moderate from wind and low <br />from water. <br />Most of this mapping unit is used for non-irrigated and irrigated hay and pasture. Present and <br />potential productivity of the soil is good. <br />14E - Burnette Loam, 12 to 25 Percent Slopes <br />This is a deep, well drained soil that occurs throughout the area to be mined. This soil <br />provides the best and most abundant source of plant growth medium of the soils in the permit <br />area. The death of useable soil is extremely variable, depending upon slope and location, and <br />in the bottom of the Streeter drainage the A horizon has been found to be as thick as twenty <br />(20) feet. The soil developed in mixed sandstone and shale and is found on upland valley <br />sideslopes and benches. The average annual precipitation ranges from 16 to 18 inches, the <br />average annual soil temperature is 43°F to 45°F, the mean summer soil temperature is 56 to <br />56°F., and the frost-free season is 70 to 90 days. <br />Included within this mapping unit are a few small areas of sandstone or shale outcrops and <br />small areas of Work and Campspass soils. <br />The duff layer consists of decomposed and undecomposed leaves, twigs, and grass. Typically <br />the surface layer is a dark grayish brown loam about 20 inches thick. The subsoil is a light <br />yellowish brown clay loam about 25 inches thick. The substratum is a light yellowish brown <br />clay loam to a depth of 60 inches. <br />Permeability is moderate. The available water capacity is high. Effective rooting depth is 60 <br />inches or more. Surface runoff is slow, and the erosion hazard is moderate from wind and <br />high from water. <br />Most of this mapping unit is native range and used for grazing. Present and potential <br />productivity of this soil is good. <br />(4F - Burnette Loam, 25 to 65 Percent Slones <br />This soil has the same characteristic as the previous soil, except it is found on steeper slopes. <br />It developed in mixed sandstone and shale and is on upland valley sideslopes.
