Discuss the formation and distribution of black soil, arid soil and forest soil.
Answers
Answer:
Black soil-It is formed by weathering of volcanic(basalt)rock formed by the Deccan lava.
Arid soil-It has originated from the mechanical disintegration of the ground rocks or is blown from the Indus basin and the coast by the prevailing south-west monsoon winds.
Forest soil-The formation of these soils is mainly governed by the characteristic deposition of organic matter derived from forest growth.
Explanation:
The formation and distribution of black soil, arid soil and forest soil are given below:
Black soil:
Soil has maturity and it has high capacity retention of water. The granules of soil swells and when wet, when dried, becomes sticky and shrinks. This soil has rich amounts of magnesium, phosphorous, magnesium, nitrogen and potash.
Arid soil:
It is deposited primarily through wind operations. It has very high levels of salt. Lack of humus and humidity. The content of kankar or impure calcium carbonate is high, limiting water infiltration. There is inadequate nitrogen and ordinary phosphate.
Forest soil:
It is present in high-rainfall regions. The content of humus is lower and therefore the soil is acidic in nature.
