Soil fertility is function of nutrient availability in the soil. Continuous cropping in the same piece of land results to nutrient exhaustion. In recent past, rapid decline of soil fertility in Indo-Gangetic plain drawing attention of researchers. To know fertility and nutrients availability in alluvial soil of Mirzapur this experiment was conducted and correlation between different nutrients were traced. Altogether 45 surface soil samples were collected and analyzed for different soil parameters. Results obtained showed that organic carbon was medium to high, nitrogen was extremely low, phosphorus and potassium were high, exchangeable cations (Ca and Mg) were adequate and sulphur was medium. On correlation analysis it was found that pH and EC were significantly and negatively correlated to each other. Significant positive correlation existed between EC and phosphorus, EC and potassium, OC and Fe, phosphorus and Fe, potassium and Fe, Ca and Mg, Ca and Cu and between Fe and Cu while Cu and Zn showed significant negative correlation.
