(c) Soils

In agricultural operations, soil is probably the most important determining physical factor. It determines the cropping patterns, their associations and production. The fertility of soil, its texture, structure and humus contents have a direct bearing on crops and their productivity. In general, the alluvial soils are considered to be good for wheal, barley, gram, oilseeds, pulses, and sugarcane; while the clayey loam gives good crop of rice. TZi^wrsoil is known for cotton, and sandy soil for bajra, guar, pulses (green-gram, black-gram, red-gram, etc.). The saline and alkaline soils are useless from the agricultural point of view unless they are reclaimed by chemical fertilisers and biological manures and fertilisers.
