Abstract
An experiment was undertaken to know the influence of bund planted teak trees on soil chemical properties during 2020-21 at farmerââ¬â¢s field in Agroclimatic Zone 3 (Northern Dry Zone) of Karnataka, India. The study revealed significant improvement of soil chemical properties under bund planted teak trees as compared to control (without trees). Significantly, higher soil organic carbon content, available N, P2O5 and K2O (0.42%, 236.5, 19.13 and 222.24 kg ha-1, respectively) was recorded on Western direction of North- South planting as compared to other direction and significantly higher organic carbon, available N, P2O5 and K2O (0.51%, 262.30, 20.48 and 239.5 kg ha-1, respectively) were recorded near tree line at a distance (2-7 m) and were decreased with increase in distance from the tree line. However, soil pH and EC did not differ significantly with direction and distance whereas, numerically lower soil pH and EC were recorded in bund planted field as compared to the control (without trees). Further, among the interactions significantly higher organic carbon, available N, P2O5 and K2O (0.52% 270, 21.20 and 248.61 kg ha-1, respectively) were recorded on Western direction near tree line at distance (2-7m) and the present investigation noticed improvement of soil chemical properties under bund planted field up to a distance of 17 m from the tree line. In conclusion the bund planting had significantly improved soil chemical properties as compared to control (without trees) and planting of trees at interval of 20 meters is suggested
