TABLE 1.1 <br />LAND CAPABILITY CLASSES <br />Capabi/ity classes, the broadest groups, are designated by Roman numerals I though VIII. The numeral. <br />indicate progressively greater limitations and narrower choices for practical use. <br />CLASSIFICATIONS DEFINITIONS <br />Class I Soils have few limitations that restrict their use. <br />Class II Soils have moderate limitations that reduce the choice of plants or that require <br />moderate conservation practices. <br />Class III Soils have severe limitations that reduce the choice of plants, or that require <br />special conservation practices, or both. <br />Class IV Soils have very severe limitations that reduce the choice of plants, or that require <br />very careful management, or both. <br />Class V Soils are not likely to erode but have other limitations, impractical to remove, that <br />limit their use. <br />Class VI Scils have severe limitations that make them generally unsuitable for cultivation. <br />Class VII Soils have very severe limitations that make them unsuitable for cultivation. <br />Class VIII Soils and landforms have limitations that nearly preclude their use for commercial <br />crop production. <br />Capabi/ity subclasses are soil groups within one class; they are designated by adding a small letter to th~ <br />class numeral. <br />CLASSIFICATIONS DEFINITIONS <br />e This letter shows that the main limitation is risk of erosion unless close-growing <br />plant cover is maintained. <br />w This letter shows that the water in or on the soil interferes with plant growth or <br />cultivation (in some soils the wetness can be partly corrected by artificial drainage) <br />s This letter shows that the soil is limited mainly because it is shallow, droughty, or <br />stony. <br />c This letter shows that main limitation is climate that is too cold or too dry. <br /> <br />Soils Description Report • West Elk Mine <br />December 1994 WESTEC 66 <br />
