Abstract:
This article presents a study on impact of different land use systems on the physico- chemical properties of soil in Kohima district, Nagaland. It was undertaken during 2020-2021 in the Department of Agricultural Chemistry and Soil Science, SASRD, Nagaland University. A total of sixty samples (60) surface soil samples (0-15 cm) were collected from twelve villages of the four blocks (4) of Kohima district from cereal, orchard, banana plantation, spice and vegetable land use practices and were analysed for different properties. On an average soil pH, EC and CEC ranged from 4.38 to 5.96, 0.06 to 0.32 dSm^-1 and 8.4 cmol (p⁺) kg^-1 to 24.3 cmol (p⁺) kg^-1. Bulk density, particle density and porosity ranged from 1.03 to 1.23 g cm^-3, 2.42 to 2.52 g cm^-3 and 49.80 to 58.47%. On the basis of average value, soils of all the land use system were found to be medium to high in available N, low to medium in available P, K and S. High amount of organic carbon, available N, P, K and S were reported in orchard while lower amount of the same were reported in banana plantation.
