Abstract
The top porous layer of the earth's surface that is fertile is called soil. The role of soils in nature and in society is enormous. Soil is a living environment, a source of nutrients for organisms, and plays an important role in the small biological and large geological circulation of substances. Soil is composed of solid, liquid, and gaseous components and is formed as a result of the complex interaction of climate, rocks, plants and animals, and microorganisms. 1 gram of soil contains more than a million simple animals and low plants.
