GPS based three hundred and three surface soil samples (0-15 cm) were collected from dominant cropping system and analyzed for different soil characteristics in laboratory using standard procedures. The results were statistically interpreted that the N, P, K, and S were found to be deficient in 56.77, 31.68, 6.6 and 52.48 percent soil samples, respectively. Geo-statistical results revealed that the exponential model was found best fit for available N, P, K, and S. Spatial distribution maps showed that soil pH, EC, organic carbon, calcium carbonate, N, P, K, and S spatially varied and were deficient in Hundia, Timarani, Khirkiya and Sirrali. These maps will be helpful for farmer’s to decide the quantity of fertilizer to be added to soil to improve fertility status for sustainable crop production and environmental protection.
