Correct Answer : Black soil
Correct Answer : All the above
Due to intensive leaching and low base exchange capacity, typical laterite soils generally lack fertility and are of little use for crop production. But when manured and irrigated, some laterites and lateritic are suitable for growing plantation crops like tea, coffee, rubber, cinchona, coconut, etc. In low lying areas paddy is also grown
These soils are also called as regur soils. Central India and Deccan plateau mainly constitutes this type of soil.
Correct Answer : 8
The Indian Council of Agricultural Research (ICAR) set up an All India Soil Survey Committee in 1953 which divided the Indian soils into eight major groups. They are (1) Alluvial soils, (2) Black soils, (3) Red soils, (4) Laterite and Lateritic soils, (5) Forest and Mountain soils, (6) Arid and Desert soils, (7) Saline and Alkaline soils and (8) Peaty and Marshy soils
Correct Answer : Desert soils
These soils are found in Thar desert in the Indian state of Rajasthan. This soil is formed from arid conditions with practically negligible rainfall. This type of soil is highly pervious and has a low density. It requires densification to increase its bearing capacity and shearing strength. Commonly recognised plants that grow in these soils are cacti.
