Detailed explanation-1: -Desert soil is mostly sandy soil (90–95%) found in low-rainfall regions. It has a low content of nitrogen and organic matter with very high calcium carbonate and phosphate, thus making it infertile. The amount of calcium is 10 times higher in the lower layer than in the topsoil.
Detailed explanation-2: -Infertile soils lacking in decomposing organic matter such as manure, will lack nutrients and binding qualities as well. Incidence: Soils have been found to be naturally deficient in one or more of all the essential elements.
Detailed explanation-3: -Most experts agree that a desert is an area of land that receives no more than 25 centimeters (10 inches) of precipitation a year. The amount of evaporation in a desert often greatly exceeds the annual rainfall. In all deserts, there is little water available for plants and other organisms.
Detailed explanation-4: -Fertile soil is rich in fundamental elements and minerals, has good aeration, water holding capacity, and good texture.
