Major Types Of Soils



Soil types are classified according to many factors. They are classified on the basis of colour, depth, pH, productivity, texture and process of formation.

Soil types according to depth are as follows:
1) Shallow Soil – Soil depth less than 22.5 cm. Only shallow rooted crops are grown in such soil, e.g. Paddy, Nagli.
2) Medium deep Soil – Soil depth is 22.5 to 45 cm. Crops with medium deep roots are grown in this type of soil e.g. Sugar cane, Banana, Gram.
3) Deep soil – Soil depth is more than 45cm. Crops with long and deep roots are grown in this type a soil e.g. Mango, coconut

The committee appointed by the Indian Council of Agricultural Research (ICAR), classified the Indian soil in the following main groups:

The main types of soil in India are as follows:

  1. Red soils
  2. Laterites and lateritic soil
  3. Black soil
  4. Alluvial soils
  5. Forest & hill soils
  6. Peaty and marshy soils
