Gadag district (Northern Dry Zone of Karnataka) features predominantly red and red–brown soils developed on metamorphic and volcanic parent materials. Recent local surveys and micro-watershed studies show soils with neutral to slightly alkaline pH, low organic carbon and available nitrogen, medium phosphorus, and generally adequate to high potassium and sulfur — a pattern typical of semi-arid, rainfed regions where crop removal and low organic additions have depleted N and C reserves. This article summarises key findings from field studies and state surveys and draws practical implications for nutrient management and soil health in Gadag.
