Organic matter : Tests of the permit area showed <br /> the percent of organic matter contents range from low to <br /> very high, the high levels are obviously due to large <br /> amounts of coal material in many of the areas. <br /> Samples in the tunnel area (1979) indicated a <br /> great deal of organic matter is present (common to forest <br /> soils) . <br /> Major Plant Nutrients : Testing in the permit area <br /> indicates major plant nutrients (nitrate-nitrogen, Phos- <br /> phorous and potassium) are relatively low. <br /> Samples of the tunnel area (1979) indicated higher <br /> potassium content of the soils , sufficient to support vegeta- <br /> tive growth. Further, several of the nitrate concentrations <br /> are relatively high, except samples taken in the Mancos <br /> Shale, which showed very low concentrations of all the <br /> components . <br /> 7. Topsoil <br /> Topsoil is generally thin in the permit area. Topsoil will <br /> be salvaged as required in areas of surface disturbance, anticipated to <br /> be in the Sutey refuse disposal area, and in conjunction with construction <br /> of additional sedimentation ponds. <br /> Topsoil redistribution has been done, although not completed, <br /> on the old coal refuse pile. The redistributed topsoil consists of <br /> A and B horizon material, the only soil available in the area, spread <br /> 14 <br />
