Answer 1

The correct option is A a) 1, 2 and 4


Answer- A
Alluvial Soils are immature and have weak profiles due to their recent origin.
Black soil being clayey and fine textured has high water retention capacity.
Red soils are usually poor growing soils, low in nutrients and humus and difficult to cultivate because of its low water holding capacity.These soils are deficient in lime, magnesia, phosphates, nitrogen, humus and potash. Intense leaching is a menace to these soils. Under irrigation, they can produce excellent crops like cotton, wheat, pulses, tobacco, jowar, linseed, millet, potatoes and fruits.
