For evaluation of the soil fertility status of Nagari block, a systematic survey was carried out. Surface (0–15 cm depth) soil samples were collected from 123 Villages of Nagari block using GPS (Global Positioning System) marked where 164 samples were identified from Vertisol. These soil samples were analysed for Fe Mn Cu and Zn and categorized as sufficient and deficient as per criteria followed in the soil testing laboratory. Based upon the coefficient of correlation between micronutrients and soil Properties, A non-significant and negative correlation of available Zn with pH was observed in Vertisols of Nagari block. The availability of Zn content show higher values may due to their solubility effects. The correlation of Fe with EC was negative and non significant. Positive and significant correlation was found between available zinc and electrical conductivity. Organic carbon was negatively and non-significantly correlated with available content of zinc.
