Question

For the cultivation of cotton ________ is suitable.
A. Alluvial soil
B. Laterite soil
C. Black soil
D. Red soil

Answer 1

Hint: It is a mineral soil that is enriched with organic carbon that is at least 25 cm deep. Two categories of this soil (1st and 2nd categories) are recognized.

Complete answer:
Black soil is ordinary of the Deccan trap (Basalt) locale spread over northwest Deccan level and consists of magma streams. They cover the levels of Maharashtra, Saurashtra, Malwa, Madhya Pradesh, and Chhattisgarh and stretch out the south-east way along the Godavari and the Krishna valleys. Otherwise called regur soil, black soil is ideal for developing cotton and is known as black cotton soil. They are wealthy in soil supplements, for example, calcium carbonate, magnesium, potash, and lime. These soils are commonly poor in phosphoric substance.

The black soils are clayey soil, notable for their ability to hold dampness. The filtering has just prompted an expanded centralization of clastic substance. Black soil is the best appropriate for the development of cotton crops. what's more, it is likewise called black cotton soil. They are poor in humus yet exceptionally dampness retentive, in this manner reacting admirably to the water system. Those soils are likewise found on numerous fringe plots where the fundamental basalt has been moved from its unique area by fluvial cycles.

The filtering has just prompted an expanded convergence of clastic substance. The soils are commonly rich in montmorillonite and beidellite gathering of mud minerals. Black soils are generally appropriate for the cotton crop henceforth it is otherwise called black cotton soil. Other than cotton, the soil is appropriate for the development of yields like wheat, groundnut, chilies, tobacco, and jowar.

Thus, option (C) is correct.

Note: Black kinds of soil are most appropriate for cotton development. Black soil holds dampness well indeed and tacky when wet. Because of the low void space in black soil, the capacity of the invasion of downpour or inundated water is exceptionally less in black soil.
