Abstract: The present study was conducted at farmer’s fields under the guidance of Department of forestry, JNKVV, Jabalpur, Madhya Pradesh during the year 2015-2016 to evaluate physico-chemical properties and SOC stock under different nine land use systems (viz., four sole cropping land use namely paddy-wheat sole cropping, soybean-mustard sole cropping, moong - wheat sole cropping, pigeonpea sole cropping, one eucalyptus sole plantation, and four agrisilviculture land uses- eucalyptus+ paddy-wheat agrisilviculture, eucalyptus + soybean-mustard agrisilviculture, eucalyptus + moong - wheat agrisilviculture, eucalyptus + pigeonpea agrisilviculture) at three soil depth (0-15, 15-30 and 30-45 cm). The study revealed that, soil pH and EC were not influenced statistically by different land use system. However, Physico-chemical properties (viz., OC, bulk density and available N, P, & K) and SOC were influenced by different land use systems. Significantly highest available N, P, K and SOC stock was observed under Eucalyptus + pigeonpea agrisilviculture system (T9) and lowest was under moong-wheat conventional cropping land use system (T3). Theses soil parameters gradually decreased with successive increasing soil depths. But soil bulk density revealed reversed trend and it was significantly highest under moong-wheat conventional cropping (T3) and lowest was under eucalyptus + pigeonpea agrisilviculture (T9) land use system at all the soil depths and also increased with successive decreasing soil depths The correlation study showed that, the OC (%), EC, available N, P and K exhibited highly positive significant correlations with soil organic carbon (SOC) stock, while the soil pH and bulk density had highly negative significant correlations with SOC stock.
