Regosols

Regosols are found in areas where soil has been eroded to the extent that the underlying unconsolidated materials come near to the surface, or where soil formation has not played an important role, e.g. in desert regions. The name comes from the greek 'rhegos' :blanket meaning young soils on weathering materials.

Characteristics

Soils in medium and fine textured materials, having no distinctive horizons other than an ochric horizon at the surface.

Use

Commonly used for extensive grazing, but best for forests. In steppe region with 500- 1000mm ppt this soil needs frequent application of water. So dry farming is economically advised.
