REGUR SOIL (black soil).
LATERITE SOIL. ALLUVIAL SOIL. : ALLUVIAL SOIL. This is the most important and widespread category. It covers 40% of the land area. In fact the entire Northern Plains are made up of these soils.

Red soils cover the eastern part of the peninsular region comprising Chhotanagpur plateau, Orissa, eastern Madhya Pradesh, Telangana, the Nilgiris and Tamil Nadu plateau. LATERITE SOIL. : LATERITE SOIL. Laterite soils results in intense leaching owing to heavy tropical rains.
They are found along the edge of plateau in the east covering small parts of Tamil Nadu, and Orissa and a small part of Chhotanagpur in the north and Meghalaya in the north-east.
