This type of soil is black in colour. These soils are also called as regur soils. In the north-western found Deccan Plateau. [5] The soil is suitable for growing cottons, due to which it is also known as black cotton soil. It is believed that the climatic conditions along with the parent rock material are the important factors for the formation ...
Chernozem (/ ˈ tʃ ɜːr n ə z ɛ m / CHUR-nə-zem), [a] also called black soil, regur soil or black cotton soil, is a black-colored soil containing a high percentage of humus [3] (4% to 16%) and high percentages of phosphorus and ammonia compounds. [4] Chernozem is very fertile soil and can produce high agricultural yields with its high ...
The type of soil and its texture is also a major determining factor in the biological soil crust's relationship with water retention and filtration. Soils with a large presence of sand (less soil and clay) have high levels of water retention in their surface levels but have limited downward movement of the water.

A represents soil; B represents laterite, a regolith; C represents saprolite, a less-weathered regolith; beneath C is bedrock. Saprolite is a chemically weathered rock. Saprolites form in the lower zones of soil profiles and represent deep weathering of the bedrock surface. In most outcrops, its color comes from ferric compounds.
Soil layers, from soil down to bedrock: A represents soil; B represents laterite, a regolith; C represents saprolite, a less-weathered regolith; below C is bedrock Tropical weathering (laterization) is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting ...
Since the origin of agriculture, humans have understood that soils contain different properties which affect their ability to grow crops. [4] However, soil science did not become its own scientific discipline until the 19th century, and even then early soil scientists were broadly grouped as either "agro-chemists" or "agro-geologists" due to the enduring strong ties of soil to agriculture.
The institute conducts multi-disciplinary research to seek solutions to the problems of farming in arid regions of the country. The hot arid zone covers about 32 million ha area in the states of Rajasthan, Gujarat, Punjab, Haryana, Karnataka and Andhra Pradesh, while the cold arid zone, covering about 7 million ha area, is located in the states ...
