Abstract
An investigation was undertaken to evaluate the soil properties of different land use systems viz. Jhum field (1st year), Jhum field (2nd year), Large cardamom based agro forestry system (4 year old), Orange based farming system (15 year), Jhum fallow (4 year) and Forest (>20 year) in Longleng district of Nagaland. Highest available P was recorded 21.91 kg/ha under Jhum 1st year, whereas lowest available K was found (219.81kg/ha) under Large cardamom agro-forestry system (4 year). Forest soil were recorded 7.70%, 14.15%, 26.16%, higher pH, SOC, available N respectively as compared to Jhum fallow 2nd year. Result revealed that maximum value of pH (5.31), SOC (2.58 %) and available N (413.95 kg/ha) were recorded under forestland (more than 20 years) followed by Orange based farming system as compared to other land use system.
