The soils of Udaipur were studied for their Fe, Mn, Cu and Zn status in relation to important soil properties. Available Fe, Mn, Cu and Zn contents ranged from 0.62–32.84, 5.20–35.57, 0.05–11.54 and 0.32–11.65 mg kg−1 with the mean values of 11,59, 18.86, 1.82 and 2.26 mg kg−1, respectively. Electrical conductivity, pH, organic carbon and calcium carbonate in soils ranged from 0.06–2.24 dS m−1, 6.9–8.9, 1.8–10.6 g kg−1 and 3.5–113.0 g kg−1 with mean values of 0.41 dS m−1, 7.4, 6.17 g kg−1 and 27.7 g kg−1, respectively. Amounts of available Mn and Cu in these soils found sufficient to support plant growth. Only 4.55 per cent soil samples in available Zn and 6.36 per cent soil samples in available Fe found deficient. The available Fe, Mn, Cu and Zn showed positive and significant correlarion with organic carbon and these found negatively and significantly correlated with pH and calcium carbonate content ofsoils.
