Abstract
The present investigation was carried at Sam Higginbottom university of Agriculture Technology and Sciences in the department of Soil Science and Agricultural Chemistry lab. In this study, a total of 24 soil samples were collected from eight different villages on 01 November 2020 in Chaka block of Prayagraj district and from each village 3 soil samples were collected and analyzed for their Physico-chemical parameters by using standard laboratory techniques. According to the critical limits of soil nutrients the results observed, 70 to 80% soil samples were in low to medium range for Nitrogen (N) (51-648 kg ha-1), Phosphorus (P) (0 – 48 kg ha-1) and Potassium (K) (78.4 – 392 kg ha-1). The micro-nutrients (Zn, Fe, Mn, Cu) of soil samples are observed deficiency range due to inverse relationship with pH i.e., increase in pH causes reduction in availability of Zn, Fe, Mn, Cu. According to the Nutrient Index Values, Chaka block was found to be medium category for Organic carbon (2.25), Nitrogen (1.70), Phosphorous (2.29), and Manganese (1.70). Low category was found in Potassium (1.37), Sulphur (1.29), Zinc (1.08) and Iron (1.41). High category was found in Copper (2.66). The results showed that improvement has to be done for improving soil fertility and quality by practicing the improving cropping pattern, decomposition of organic waste, mulching and tillage practices.
