Why are arid soils found to be non-productive?
- These soils are generally sandy in texture and saline in nature.
- In some areas, the salt content is very high and common salt is obtained by evaporating the water.
- Due to the dry climate, high temperature, evaporation is faster and the soil lacks humus and moisture.
- The lower horizons of the soil are occupied by kankar, which restricts the infiltration of water
