Abstract: The precise nutrient management is one of the most important and integral part of the modern-day agriculture. For this to happen we have to know the spatial variability of soil fertility. In this study, all soil physico-chemical properties (pH, EC, OC), Available macronutrients (N, P, K, S) and Available micronutrients (B, Fe, Mn, Cu, Zn) status with their spatial variability in KVK farm of Pahanda was quantified and based on their result soil fertility maps were prepared for respective nutrients using Arc-GIS software. Total 52 soil samples from soil surface (0-15 cm) collected from the study area and analyzed for these parameters. Soil reaction of the study area varied from neutral to saline range with EC below<1.0 dS/m for all collected samples. Soil OC content was low to medium, Soil N and P in low, Soil K medium to high fertility category and S status found to be ranging between 11.20 to 39.60 kg/ha. Also, Fe, Cu and Mn status found in medium to high range but Zn status found deficient in about 83% samples. Hot water extractable B content in 36.54% samples found in low and rest in medium fertility range. These observed spatial variability used in further fertilizer recommendation and input management based on requirement of crop plants.
