A Spatial Distribution of Organic Carbon status in Koppal and Yadgir Taluks of Karnataka, India using GIS and Geostatistics

Spatial distribution of Soil Organic Carbon (SOC) status is necessary for enhancing crop and soil productivity. In this study, samples were collected from Koppal Yadgir taluks (Northern dry zone Northeastern zone) Karnataka at 320 m grid interval 0–15 cm depth assessed organic carbon map was prepared under GIS using Arc 10.4 Geowizard Kriging method. The results the study showed that, SOC medium in 37 per cent high 26 total area (1,38,298 ha) taluks. Whereas, taluks, 38 31 (1,71,060 ha). descriptive statistics positively skewed with positive kurtosis value. spatial variability a moderate dependence spherical model both Therefore, most soils status. There need integrated nutrient management additional emphasis sustainable production.
