Soil Science:

Soil science is the study of soil as a natural resource, including its composition, properties, and processes. It involves understanding the physical, chemical, and biological characteristics of soil, as well as its formation, classification, and management.

Branches of Soil Science

1. Pedology: Study of soil formation, classification, and morphology.
2. Edaphology: Study of soil-plant relationships and soil fertility.


Soil & Components of soil

Soil is a complex, dynamic, and living system composed of:

1. Mineral particles: Sand, silt, and clay particles derived from rocks and minerals.
2. Organic matter: Plant and animal residues, microorganisms, and humus.
3. Water: Soil solution containing dissolved nutrients, ions, and gases.
4. Air: Soil atmosphere containing oxygen, carbon dioxide, and other gases.


Soil Formation

Soil formation is a complex process involving the interaction of physical, chemical, and biological factors. It involves the weathering of rocks and minerals, the decomposition of organic matter, and the accumulation of soil particles.

Factors Affecting Soil Formation

1. Parent material: Type of rock or mineral from which the soil is derived.
2. Climate: Temperature, precipitation, and weather patterns that influence soil formation.
3. Topography: Slope, aspect, and elevation that affect soil erosion, deposition, and formation.
4. Biological activity: Plants, animals, and microorganisms that contribute to soil formation and development.
5. Time: Duration of soil formation, which influences the degree of weathering, decomposition, and soil development.

These factors interact and influence one another, resulting in a diverse range of soils with unique characteristics and properties.
