- Sandy soils are light, dry, warm, low in nutrients and often acidic.
- Silt soils are fertile, light but moisture-retentive, and easily compacted.
- Loams are mixtures of clay, sand and silt that avoid the extremes of each

Forest soil :- ( i)The soil texture varies according to the mountain environment where they are formed .
( ii) They are loamy and silty in valley sides and coarse grained in the upper slopes.
