Abstract:
Soil properties under six types of vegetative covers, evergreen, semi-evergreen and
moist deciduous forests, and plantations of teak, eucalypt and rubber showed that they differed
significantly. Soils in the natural forests have higher water holding capacity, cation exchange
capacity, organic carbon, N, PzOs, K2O and CaO and MgO. Soils in the plantations, on the other
hand, possess greater accumulation of gravel, contain highest amounts of FezOs and AhCb. Organic
carbon and N contents up to an appreciable depth were considerable in soils under natural forests.
It was found that growing eucalypt after clearfelling natural forests has deleterious effect on soil
properties.
