Assessment of spatial variability of soil fertility status in KVK farm of Pahanda in Durg district, Chhattisgarh using Gis-Gps

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
