Soil refers to a layer of loose material on the earth's surface, which is composed of various granular minerals, organic matter, moisture, air and microorganisms, and can grow plants. Soil consists of minerals formed by weathering of rocks, organic matter generated by decomposition of animal, plant and microbial residues, soil organisms (solid substances), water (liquid substances), air (gas substances), oxidized humus, etc.

Solid substances include soil minerals, organic substances and nutrients obtained by microorganisms through light sterilization. Liquid substances mainly refer to soil moisture. Gas is air existing in soil pores. These three substances in the soil constitute a contradictory unity. They are interrelated and mutually restricted, which provide necessary living conditions for crops and are the material basis of soil fertility.
