• economic importance occurring within the proposed tract boundary. , <br />E. Soils - There are seven soils occurring within the proposed lease area: <br />Gelkie sandy loam (X30AF,), Blevinton sandy loam (X15AE), Morset loam <br />(45AE), Spicerton sandy loam (X31AC), Aaberg Barishman clay (X21AE)., <br />Crespin-Carlstrom stony clays (Y.22AE), and Cryorthents (X60). (See Afap j). <br />The Gelkie sandy loam covers approximately 10% of the lease area. <br />This soil is found on upland terraces and benches, is fairly deep <br />and taell drained. Funoff is medium with a slight erosion hazard <br />rating from blowing and a moderate erosion rating from water. <br />The Blevinton sandy loam also consists of deep, well-drained <br />soils occurring in concave areas of valley sideslopes and receives <br />additional water during periods of spring runoff. Erosion hazard is <br />slight. This soil covers approximately 5% of the lease area. <br />• The Pforset loam soils cover approximately 409. of the subject area <br />and occupies the high terraces in the northwest portion of the <br />lease area. These soils are deep and well drained. Permeability <br />is moderate and the available water capacity is high with a medium <br />runoff. Erosion hazard ratings for both wind and water are slight. <br />Spicerton sandy.loams comprise the stream channels and in[ergrade <br />into the broader stream basins. The Spicerton soils cover approxi- .~ <br />mately IS% of the proposed lease site. The surface texture of these- <br />soils is composed of sandy loam or loamy fine clay subsoil. The <br />presence of the clay subsoil lends to slow permeability and, therefore, <br />the water erosion hazard for these soils is rated high. The water- <br />holding capacity is moderate, yet much of the soil moisture is not <br />available for plant growth due to the salt content of the soil, as <br />• the depth to calcareous material ranges from 0 to 6 inches.
