Scope of Soil Science




  • Soil Science has six well defined and developed disciplines. Scope of soil Science is reflected through these disciplines.

    Soil Science : The science dealing with soil as a natural resource on the surface of the earth, including Pedology (soil genesis, classification and mapping) and the physical, chemical and biological and fertility properties of soil and these properties in relation to their management for crop production.

    1. Soil fertility: Nutrient supplying properties of soil

    2. Soil chemistry: Chemical constituents, chemical properties and the chemical reactions

    3. Soil physics: Involves the study of physical properties

    4. Soil microbiology: deals with micro organisms, its population, classification, its role in transformations

    5. Soil conservation: Dealing with protection of soil against physical loss by erosion or against chemical deterioration i.e. excessive loss of nutrients either natural or artificial means.

    6. Pedology: Dealing with the genesis, survey and classification

     

    Soil can be compared to various systems of human body

    Digestive    – matters decomposition 
    Respiratory – air circulation & exchange of gases 
    Circulatory – water movement with in the soil system 
    Excretory   – leaching out of excess salts 
    Brain         – soil clay 
    Colour       – soil colour 
    Height       – soil depth

    Components of Soil (Volume basis)

    Mineral matter – 45% 
    Organic matter – 5% 
    Soil water – 25% 
    Soil air – 25%
