Abstract

Rehabilitation of abandoned and denuded land by plantation of multipurpose tree species
(MPT) was done at Golaghat district of Assam. Composite soil samples were collected before
plantation and after every six months from 14 non-legume and 6 legume plantation sites at three
soil depths i.e. 0-25, 25-50 and 50-100 cm. Soil physical properties showed no significant change
with chemical properties showing much variation. Five years after plantation, surface and
subsurface soil pH decreased from initial values under both legume and non-legume. While soil
organic carbon showed an increasing trend after an initial decrease in all species. Higher soil
organic carbon was recorded under non-legume than legume. Total nitrogen in soil increased
uniformly under all species. At lower depth, it showed much variation among the species.
Subsurface soils contained high amount of available phosphorous. Leguminous tree contributed
more available soil phosphorous than non-leguminous trees. Drastic decline in case of
exchangeable potassium in every plantation site was observed although it later increased.
Exchangeable Ca and Mg content decreased sharply from the initial values.
