Spatial variability analysis of soil properties of Gwalior District, Madhya Pradesh

Abstract

The application of fertilizers can be optimized to maintain crop yield while reducing the amount of fertilizer input. One way to achieve this is by using soil fertility maps and fertilizer recommendations to regulate fertilizer application. In this study, statistical techniques were employed to analyze the physical-chemical quality of soils in the Gwalior region of Madhya Pradesh. The study involved collecting 95 soil samples (0-15 cm) from four blocks in the Gwalior area using GPS (Bhitarwar, Morar, Ghatigao, and Dabra), and conducting laboratory analyses. The results of the analysis showed that the pH, EC, and OC of the soil samples ranged from 7.10 to 8.90, 0.21 to 0.83 dS/m, and 0.23 to 0.98%, respectively. The soil samples also had varying levels of N, P, and K, with values ranging from 194 to 336, 6.10 to 45.00, and 69.89 to 751.30 kg/ha, respectively. The study revealed significant differences in the physicochemical properties of soil in the study area
