ABSTRACT
The study site was located at the “National Botanical Research Institute of Banthara Farm, Lucknow” in North India. The study was to evaluate the ameliorative effect of various tree species on salt affected soil. Amelioration of salt affected soils by tree species was planned and excavated in the salt affected soil during the year 2004-05. After 40 years of tree plantation viz. Albizia lebeck, Bauhunia ecumilata, Cassia fistula, Dalbergia sissoo, Erythrina indica, Eucalyptus tereticonis , Leucaena leucocephala, Deris indica, Prosopis juliflora, Syzygium cumini, Tectona grandis, the soil samples from soil profiles was taken and analysed and compared with the initial data recorded at the time of plantation of various tree species. Other parameters viz. the height, diameter and mineral composition of leaves (N, P, K, Ca, Mg, Na and K/Na ratio) were determined and the data so generated have been analyzed.
The result of mechanical separate and texture show that there was by and large non-significant difference in these properties in comparison to control values. There was significant decrease in bulk density (1.89 to1.30 Mg m-3) and particle density (2.72 to 2.30 mg m-3) but significant increase in the porosity (27.30 to 47.63%), water holding capacity (16.33 to 52.10%) and moisture equivalent (13.00 to 29.90%) of the surface soil (0-15 cm) under the Leucaena leucocephala in comparison to control. The tree species studied, in general, were effective in bringing abrupt improvement in soil physico-chemical properties as reflected by the change in pH, EC, ESP, organic carbon and CEC. Higher organic carbon percentage (0.07 to 0.95%) and CEC (11.96 to 27.00 C mol (P+) kg-1) were recorded under Leucaena leucocephala. The pH, EC and ESP values were lowest under Leucaena leucocephala in comparison to other tree species. The pH, EC, ESP and exchangeable Na+ increase with depth, where as organic carbon, total nitrogen, and available phosphorus decreased. Exchangeable Ca++, Mg++ and K+ decreased with depth.It could be concluded that the tree species Leucaena leucocephala would be better choice for the afforestation to ameliorate the salt affected soils. The farmer may follow this practice.
