“…The soil organic carbon and available soil N, P and K increased significantly under Melia dubia plantation compared to control (field without trees) in both 0-15 cm and 15-30 cm soil depths. Mevada et al [16] also studied that the soil chemical properties viz., pH, electrical conductivity (EC), organic carbon (OC), available nitrogen (N), phosphorous (P 2 O 5 ) and potassium (K 2 O) assessed at the time of okra sowing and at final harvest varied significantly among different nitrogen management treatments under agroforestry system and in open condition. The interaction effect of years over treatments was found non-significant in pooled analysis for soil properties under teak based agroforestry system.…”

A two year experiment was conducted during kharif and rabi season of 2016-2017 and 2017-2018 at experimental site near Faculty of Forestry in main campus of Birsa Agricultural University, Ranchi, Jharkhand, India. Sole cropping and gamhar based agrisilviculture systems with four different intercrops (arhar, cowpea, greengram and mustard) were under investigation. To study the overall scenario of soil properties under agrisilviculture system, soil samples were analysed at different profile depths (0-15 and 15-30 cm) to measure the changes in soil properties under the influence of gamhar (Gmelina arborea) tree and intercrops grown in between. Soil pH, electrical conductivity (dsm-1), organic carbon (%), available nitrogen, phosphorus and potassium (kg ha-1) were found higher at the soil depth 0-15 cm as compared to 15-30 cm due to addition of organic residue on the surface soil. Soil OC, available N, P and K in 0-15 cm as well as in 15-30 cm profile was found to be statistically significant. It showed an increase from initial value in all the treatments in 2016-17 and 2017-18. The increase was more in gamhar based agrisilviculture system than in sole tree and sole crops in both the years.
