This instructional unit was designed to enable students, primarily at the secondary level, to (1) classify soils according to current capability classifications of the Soil Conservation Service, (2) select treatments needed for a given soil class according to current recommendations provided by the Soil Conservation Service, and (3) interpret a typical land capability map provided by the Soil Conservation Service. Five major sections are included: Factors to Consider in Classifying Soils (texture, subsoil permeability, depth of surface soil and subsoil, slope, erosion, drainage); Land Capability Classes (class I, E soil classes, W soil classes, S soil classes, soil classification charts); Lane Use and Treatment; Soil and Water Conservation; and Soil and Water Conservation Plan. A soil texture chart and a glossary of terms (used in classifying soil and in determining recommended land use treatments) are appended. (HD)
