“Soil” is a very broad term and refers to the loose layer of earth that covers the surface of the planet or can be defined as the organic and inorganic materials on the surface of the earth that provide the medium for plant growth. Soil develops slowly over time and is composed of many different materials. The soil is the part of the earth’s surface, which includes disintegrated rock, humus, inorganic and organic materials. The soil is usually formed when rocks break up into their constituent parts. When a range of different forces act on the rocks, they break into smaller parts to form the soil. These forces also include the impact of wind, water and the reaction from salts. There are three stages of soil: Solid soil, Soil with air in the pores, Soil with water in the pores. There are various types of soil that undergo diverse environmental pressures. Soil is mainly classified by its texture, proportions and different forms of organic and mineral compositions.
