INDIAN GEOGRAPHY

Detailed explanation-1: -The northern plains have intense deposits of alluvial soil. Alluvial soil contains amounts of lime, potash, and phosphorus. Alluvial soil helps in the growth of crops such as paddy, sugarcane, wheat, rice, maize, and other pulses. Alluvial soils are the deposits or materials from rivers.

Detailed explanation-2: -Alluvial soil is mainly found in Northern Plains. These soils are widespread in the Northern Plains and valleys. They are depositional soils, formed mainly due to silt deposited by Indo-Gangetic-Brahmaputra Rivers. When the river overflows, this soil is deposited on the riverbanks.

Detailed explanation-3: -Alluvial soil is rich in humus, lime and organic matters. It is said to be the highly fertile soil and it is deposited largely in the northern plains of India out of the deposition work of Indus-Ganga-Brahmaputra rivers.

Detailed explanation-4: -Alluvial soils are by far the largest and the most important soil group of India. The widest occurrence of the alluvial soils is in the Indo-Gangetic Plain starting from Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal and Assam in the east, northern parts of Gujrat also have some covers alluvial soils.

Detailed explanation-5: -Alluvial soil is formed from the sediments deposited by the rivers in Indo-Gangetic plains and by sea waves in the coastal plains. It is very fertile and hence, excellent for agriculture. This soil is found extensively in the northern plains and other river valleys in India.
