Soil Science

Soil science deals with soil as a natural resource on the surface of the earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils per se; and these properties in relation to the use and management of soils. There are different types of soils like Sandy, Silty, Clay, and Saline Soil etc. All soils originate, directly or indirectly, from solid rocks in the Earth's crust. Soil is the material found on the surface of the earth that is composed of organic and inorganic material.  Soil is the biologically active, structured porous medium that has developed below the continental land surface on our planet. Soils are a fantastically complex environment, teeming with life and supporting our most fundamental environmental processes. Soil contains a variety of substances. In a well-managed western soil, usually around 50% percent of the soil’s volume is composed of solid particles, while the other 50% is empty space. The branches of soil science, such as pedology are used as synonymous with soil science.
