5. Forest-Mountain soils
- They are mainly heterogeneous soils found on the hill slopes covered by forests.
- The formation of these soils is mainly governed by the characteristic deposition of organic matter derived from forests and their character changes with parent rocks, ground-configuration and climate.
- The forest soils are very rich in humus and are mostly acidic.
- They are deficient in Potash, Phosphorus and lime.
- They require good deal of fertilizers for high yields.
