The coarse textured soils occupy 26871 km2 (71.0 %) area in Jaisalmer district. Nine soil series spread over four physiographic units viz. dune complex, flat inter-dunal plain, sandy plain with scattered hummocks, and buried pediments have been recognized. Among these, the soils associated with dune complex and some of the flat inter-dunal plain and sandy plain with scattered hummocks are excessively drained, highly sandy and loose with hardly any aggregation. These have poor water retention and nutrient status. The moderately deep to deep loamy sand soils in some of these landforms and on pediments are slightly more stable and have weak sub-angular blocky solum over various types of substrata. These posses slightly higher water retention capacity and nutrient status. The flat inter-dunal part of these soils can be used for crop production during the normal rainfall years. For proper utilization, these lands have been evaluated for their suitability for crop production, horticulture, agro-forestry, silvi-pasture and pasture development. Based on climatic limitation and other soil physical constraints, each soil series has been evaluated for its land use capability. The soils have been classified into capability classes IV c s e, VI c s e, VI c sh e and irrigability classes 4 t d s, 4 d s, 3 d s and 2 d s. The soils were also classified as per Soil Taxonomy (Soil Survey Staff, 1998) at sub-group and family level.
