ABSTRACT
Delineation of available copper and manganese and their relationship with different soil properties was studied in five hundred soil samples collected from different locations of 125 villages representing the soils of Banswara district (Zone IV-B) of Rajashan. Available Cu ranged between 0.15 to 4.51 mg kg-1 with a mean value of 1.01 mg kg-1. Available Cu was found to be marginal in 0.6 and sufficient in 99.4 per cent of the studied soil samples, while available Mn ranged from 1.86 to 25.39 mg kg-1 with a mean value of 9.36 mg kg-1 and it was found to be marginal in 13.8 and sufficient in 86.2 per cent soil samples. Organic carbon, clay, and CEC were positively correlated with available Cu and Mn, while pH and CaCO3 were negatively correlated.
