The entire northern plains are made of alluvial soil. 1. The Alluvial Soil is deposited by 3 important Himalayan river systems – the Indus, the Ganga and the Brahmaputra. 2. It is also found in Rajasthan, Gujarat and eastern coastal plains particularly in the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri rivers. 3. The alluvial soil consists of various proportions of sand, silt and clay. As we move inlands towards the river valleys, soil particles appear to be bigger in size whereas in the upper side of the river valley, the soils are coarse. 4. Based on age, Alluvial soils can be classified as: 5. Old Alluvial (Bangar): The Bangar soil has a higher concentration of kanker nodules than the Khadar6. New Alluvial (Khadar): It has more fine particles and is more fertile than the Bangar. 7. Alluvial soils are very fertile. These soils contain an adequate proportion of potash, phosphoric acid and lime, which are ideal for the growth of sugarcane, paddy, wheat and other cereal and pulse crops.Q1.The entire northern plain is made up of:
