Abstract:
The Wokha District of Nagaland is located at 26.1^oN 94.27⁰E at an average elevation of 1,313 metres (4793 feet). It has a warm temperature climate. The average annual rainfall is 1940mm. The research was undertaken during 2018-2020.The surface soil samples (15 cm) were collected from five blocks of Wokha District under different land use system-forest, horticulture, rubber, paddy. The pH of the soils was found to be acidic in reaction and normal in total soluble salt concentration. The organic carbon was found to be high under forest land. The macronutrients were found to be low to medium under different land use system. CEC of forest soils was higher than horticulture, rubber, paddy land use system. The bulk density was found to be high in paddy and rubber land use system. Particle density and porosity was found to be high under forest land use. It was found that forest land use system had higher exchangeable acidity. The soil texture under different land system varied from clay to clay loam to loam. Higher soil microbial biomass carbon (SMBC) and soil respiration biomass was exhibited by forest soils.
