Soil formation

मृदा निर्माण

In this Class 9 Agriculture topic, students learn how soil develops from the weathering of rocks and the gradual addition and decomposition of organic matter. As part of “Soil and Its Properties,” the topic explains how parent material, climate, living organisms, relief, and time influence soil formation. Students also understand the development of soil layers or horizons and how differences in texture, colour, structure, and fertility are linked to the conditions under which soil forms. This foundation helps them relate soil characteristics to agricultural use and management.
