2. Factors affecting Soil Genesis

3. Soil Upper weathered layer of earth crust Medium for crop plant
Supply nutrients

4. Genesis Dictionary meaning Origin Definition
In simple word it can be defined as development of soil or formation of soil

5. Five Factors Influemce Soil Genesis
Parent Material
Climate
Topography
Biosphere
Time

6. Parent Material Definition Is the material that soil develops from
Affects the soil properties
Coarse grained soils
Fine grain soils
Affects the soil composition and structure
Affects the soil chemistry and fertility

7. Parent Material Influence decreases with time Passive Factor
Determine the type of soil

8. Climate Active Factor Two major components of climate Temperature
Precipitation
Both control the rate of soil genesis

9. Climate Different climatic regions have different types of soils
Oxisols
Soils developed in tropical climate
Ultisols
Developed in humid and sub tropical climate
Arid Soils
Developed in dry climate

10. Topography Determines runoff water
Controls the amount of soil material removed and relocated
Affects deposition and soil texture
Affects the vegetation

11. Biosphere Flora + Fauna Active Factor Effect of plants
Effect of animals

12. Time Affects soil genesis Neutral Factor
Time influences all other factors
