Question

What are the main constituents of soil?

Answer 1

1. Mineral Matter: Disintegrated rock particles made up of sand, silt, and clay that shape soil texture and provide inorganic nutrients.
2. Organic Matter: Fully decomposed plant and animal remains that increase soil fertility and water retention capacity.
3. Soil Water: Moisture in the gaps between soil particles that functions as a solvent, transporting dissolved nutrients to plant roots.
4. Soil Air: Air trapped within soil pores that provides essential oxygen to plant roots and healthy soil microorganisms.
