Abstract

The study aimed to evaluate soil fertility in Muzaffarnagar district by analyzing physico-chemical properties and nutrient contents across different blocks. Soil samples were collected from representative villages in nine blocks and assessed for pH, electrical conductivity (EC), organic carbon, and the availability of macro- nutrients (N, P, K & S) and micro-nutrients (Zn, B, Cu, Fe & Mn). Standard analytical techniques were used for laboratory evaluation. Results revealed that soil pH ranged from 7.00 to 8.36, with a district average of 7.94, indicating neutral to slightly alkaline soils. EC values were generally low (0.15–0.91 dS/m), reflecting minimal salinity concerns. Organic carbon content ranged between 1.50 and 5.80 g/kg, suggesting moderate fertility levels. Macro-nutrient analysis showed nitrogen levels varying significantly (33.7–511.5 kg/ha), with phosphorus, potassium, and sulfur also displaying wide ranges, pointing to variability in soil nutrient management. Micro-nutrient availability was block-dependent, with deficiencies in zinc and boron in several areas, while iron and manganese levels were generally adequate. The study concluded that Muzaffarnagar district soils are moderately fertile but show spatial variability in nutrient availability. Balanced fertilizer applications tailored to block-specific deficiencies are recommended to improve soil health and productivity. This baseline assessment can guide sustainable soil and crop management practices in the region.
