Effluent borne heavy metals in soil ecosystem can result into phytotoxic levels impair plant growth. Long-term accumulation of toxic metals in soils and their uptake by crop plants has a high potential for phytotoxicity besides entering into the food chain. Soils in both the districts were slightly acidic to neutral. The cation exchange capacity (CEC) was highest in maize wheat production system and least in pasture system in soils of district Samba, and whereas least was observed in rice wheat system in soils of Kathua.
