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.
