This publication deals with Region 6 of the Soil Conservation Service. Portions of five States--Kansas, Colorado, Oklahoma, Texas, and New Mexico--are included in this area, which is generally regarded as the southern Great Plains.

These groups are areas in which there is a similarity of physical conditions which in turn affect the adaptation of crops and farming practices. It is neither a soils map, a rainfall map, a topographical map, nor even a land use map. Rather the map represents the first attempt to isolate and label those bodies of land where the soil, climate, and appropriate farming practices are somewhat similar.
