Description A Long-term field study was carried out to compare the impact of ten-year old
plantation of ten multipurpose tree species, viz., Terminalia arjuna, Azadirachta
indica, Prosopis juliflora, Pongamia pinnata, Casuarina equisetifolia, Prosopis alba,
Acacia nilotica, Eucalyptus tereticornis, Pithecellobium dulce, and Cassia siamea on
tree growth, biomass yield, and physico-chemical properties of sodic soils representing
major tract of salt-affected soils of the Indo-Gangetic Alluvial Plains of India.
Maximum (100%) survival was recorded with Terminalia arjuna, Prosopis juliflora,
Pongamia pinnata, and Pithecellobium dulce whereas minimum (50%) in Prosopis
alba. Maximum plant height (9.3m) was recorded with Eucalyptus tereticornis fol
lowed by Casuarina equisetifolia (8.2m) whereas;minimum plant stature was attained
by Cassia siamea. Prosopis juliflora reported maximum diameter at stump height,
crown diameter, lopped biomass, and litter fall at all the growth stages. Prosopis juliflora
also produced highest aerial biomass (70.27Mg ha1) followed by Acacia nilotica
(63.09Mg ha1) and Casuarina equisetifolia (53.11Mg ha1). Significant improvement
in soil pH and electrical conductivity; exchangeable sodium percentage; organic
carbon; and available N, P, and K was recorded under tree plantation than natural fallow.
Significant reduction in soil bulk density (from 1.57 to 1.21mg m 3) and increase
in porosity (40.7 to 54.3%) and infiltration rate (2.10mm day 1 to 26.30mm day 1)
was recorded under tree plantations. It is concluded that tree species like Prosopis
juliflora, Acacia nilotica, and Casuarina equisetifolia have a significant impact on soil
properties, which could help to rehabilitate the sodic wastelands in the region.
