Desert soil lacks humus content but contains a high proportion of Soluble salts.
Explanation:
- Desert soils range from "red to brown" in colour. They are sandy in structure & saline in nature. Because of high temperature, dry climate, & accelerated evaporation, these soils lack humus & moisture. Nitrogen is inadequate & the phosphate content is normal.
- Desert soils are mostly found in western Rajasthan. These soils are infertile; however by way of proper irrigation & fertilizers these soils can be used to cultivate drought resistant & salt tolerant crops such as cotton, wheat, millet, maize, pulses,
- ]The soil comprise a significant amount of "soluble salts" and owing to dry climate & absence of vegetation it has very low percentage of organic matter. The soil is "alkaline" in nature since the is no rainfall which can wash away the soluble salts
- Lower horizons of the soil are occupied by ‘kankar’ layers because of the increasing calcium content downwards. The ‘Kankar’ layer formation in the bottom horizons restricts the infiltration of water, & hence when irrigation is available, the soil moisture is available for a sustainable crop growth.
