Arable soils are grouped according other management. The following <br />is a brief explanation of apDlicaDle capability classes and subgroups. Terminology is taken Irom USDA-SCS (19811. Climatic considerations are recognized in the to their potentials antl limitations for sustained cultivatetl <br />cropping. Npnarable soils are grouped according to their potentials end limitations for protlucing benefits from range, pasture, or capability classes themselves. <br />Class IV: Soils in Class IV are suited to cultivation, but have severe limitations that restrict the choice of crops antl/or require careful management practices. Special treatments and <br />conservation practices are necessary Io prevent soil blowing conserve moisture, and maintain soil protluctivity. <br />Class VI: Soils in Class VI are generally unsuited to cultivation because of severe erasion hazards, low moisture capacities, steep slopes, antl others. They may be successfully used far pasture. <br />range, woodland, wildlife, and recreation, or a combination of These. Establishment and maintenance of vegetative cover is an important consitleration on these soils. <br />Class VII: Soils in this class are unsuited to cultivation but will return a benefit from proper management practices for grazing, woodland, and wildlife uses. <br />Class VIII: Soils and lantlforms in Class VIII will not return benefits Irom management for plant protluction. Their use is chiefly restricted to wildlife, recreation, water supply, or aesthetic <br />purposes. <br />Subclass lei erosion: soils where susceptibility to erosion is dominant Dazard to than use. <br />Subclass Iwl water: soils where popr soil drainage, wetness, high water table, or overflow are dominant hazards to their use. <br />Subclass Isl soil rooting :one: soils in this subclass Dave limitations caused by shallowness of the rooting zone, stone, low moisture holding capacity, low fertility, or salinity pr sodium. <br />Subclass Icl climate: soils where temperatures or lack of moisture is the only major hazard to their use. <br />Whore correctable limitations are essentially equal, the subclasses have the following priority: c, w, s.
