Question

Black soils are ideal for cultivating cotton because ___________.
A.Their colour is black
B.They can retain moisture
C.They are made of lava
D.They are found on plateau regions

Answer 1

Hint:Black soils establish the food bin for some nations and for the world when all is said and done and are frequently perceived as innately gainful and rich soils. They are widely and seriously cultivated, and progressively devoted to grain creation, field, reach and rummage frameworks. Given great climatic conditions, these soils permit extremely high yield profitability.

Complete answer:
Among the in-situ soils of India, the black soils found in the magma covered territories are the most obvious. Those soils are regularly alluded to as regur yet are famously known as "black cotton soils," since cotton has been the most widely recognized conventional harvest in territories where they are found. Black soils are subordinates of trap magma and are spread generally across Gujarat, Maharashtra, Karnataka, and Madhya Pradesh on the Deccan magma level and the Malwa Plateau, where there is both moderate precipitation and hidden basaltic stone. On account of their high earth content, black soils grow wide breaks during the dry season, however, their iron-rich granular structure makes them impervious to wind and water disintegration. They are poor in humus yet exceptionally dampness retentive, accordingly reacting great to the water system. Those soils are likewise found on numerous fringe parcels where the hidden basalt has been moved from its unique area by fluvial cycles. The filtering has just prompted an expanded centralization of clastic substance.

Hence, the correct answer is option (B).

Note:Black soils are of specific worldwide significance in light of their pertinence to food security and environmental change. Thinking about the incredible significance of these soils, it gets essential to advance their preservation and feasible utilize and keep up their working in the more extended term to keep them supporting food security while ensuring the climate and moderating environmental change.
