INDIAN GEOGRAPHY

Detailed explanation-1: -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-2: -The rivers deposit very fine particles of soil called alluvium in their plains during the course of their long journey. It is a mixture of sand, clay and silt, called loam. These have been deposited by three important river systems-the Indus, the Ganga, and the Brahmaputra.

Detailed explanation-3: -The Northern Plain was formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the Brahmaputra along with their tributaries. It is composed of alluvial soil which has been deposited over millions of years, it is about 2400 km long and about 240 to 320 km broad.

Detailed explanation-4: -The rivers originating from the Himalayas bring rich alluvial sediments down in the plains, creating the fertile alluvial soil.

Detailed explanation-5: -The alluvial soil varies in nature from sandy loam to clay. They are rich in potash but poor in phosphorus. Two different types of alluvial soils have developed in the Upper and Middle Ganga plains – Khadar and Bhangar. Khadar is the new alluvium and occupies the flood plains of the rivers.
