Question

classofy soil and explain with example​

Answer 1

Answer:

Classification Of , soil is divided into: coarse grained soil, fine-grained soil, and highly organic soil. The particle size distribution of soil and consistency limits are used in classification of soils.

Definition of coarse-grained soil. A soil in which gravel and sand predominate. Coarse-grained soils are those least affected by moisture-content changes as most surface rain, etc., becomes gravitational water.

Fine-grained soil particles diameter that fallen between 75 micron to 2 micron are known as silt and particles having a diameter smaller than 2 micron is called clay. Coarse-grained soils have 50% or less material passing the No. 200 sieve. Fine-grained soils have 50% or more material passing the No. 200 sieve.

Soils rich in organic matter and undecomposed plant material are Histosols. They occur particularly in areas where decomposition of organic matter is hampered by cold temperatures (in Boreal climates) or where the decomposition is hampered by continuous wet conditions (in the Wet Tropics).
