Which type of soil covers the largest geographical area in India, supporting intensive agriculture across the northern plains and major river deltas?

💡 Solution & Explanation

Alluvial soils cover approximately 43 percent of India's total land area, transported and deposited by major river systems like the Ganga, Brahmaputra, and Indus. Black soils, also known as regur, develop predominantly over Deccan basalt traps and excel in moisture retention for cotton cultivation. Red soils form on crystalline igneous rocks under low rainfall conditions with iron oxide coloration. Laterite soils form in regions of high temperature and heavy leaching.
