Soil Characterization as Influenced by Rain fed Maize- Mustard Cropping Sequence under Different Agro Climatic Zone of Jammu Region

Soil characteristics under different agro climatic zone were investigated. Soil pH varied from zone to zone and higher in soils of sub tropical zone followed by soils of intermediately zone and temperate zone, where as no consistent trend in EC was observed. The values of higher organic carbon, CEC, N, P, K, S, Zn and B were noticed in soils of intermediate zone followed by soils of temperate zone, where as lower values of these parameters were found in soils of sub tropical zone. The organic carbon, CEC, silt and clay were found to be significantly and positively correlated with all the available nutrients while soil pH, EC and sand were negatively correlated.
