Micronutrient Dynamics in Major Soil Orders of Renapur Tahsil and their correlation with Physiochemical Properties

A study assessed micronutrient levels and their relationship with soil properties in Renapur Tahsil, Latur District. From 20 villages, 100 soil samples were classified into Inceptisols, Entisols, and Vertisols. In Inceptisols, Fe, Zn, Mn, and B ranged from low to high levels, while Cu was uniformly high. Entisols showed low to medium Fe and Zn, high Mn and Cu, and varied B levels. Vertisols had moderate Fe, low Zn and Mn, high Cu, and mostly low B. Overall, Zn was largely deficient (59%), followed by Fe (33%), Mn (42%), and B (34%) at low to moderate levels; Cu was high in all samples. Nutrient indices rated Zn as low, Fe, Mn, and B as moderate, and Cu as high. Micronutrients negatively correlated with pH and CaCO₃, but positively with organic carbon. The findings highlight the need for soil order- specific micronutrient strategies to improve fertility and productivity.
