Abstract:
A study was made on the influence of mahogany and teak vegetation on
soil characteristics, namely, pH, organic carbon and different forms of nitrogen.
Soils under teak were more acidic than those under mahogany. The content of
organic matter decreased with depth. Accumulation of organic matter was more under
mahogany vegetation. This was true in the case of total nitrogen also. The C:N ratio
of the soil was little influenced either by depth or by the type of vegetation. The
ratios of total N to available N, total N to ammoniacal N and total N to nitrate N
increased with increase in depth of the profile under both type of vegetation.
