Abstract: Soil health is an appropriate function of soil within ecosystem boundaries. Soil health is assessed in terms of soil physicochemical, physical, chemical and biological properties of soil. Soil health indices like Bulk density, hydraulic conductivity, water holding capacity, porosity and aggregate stability, organic carbon, available major and (N,P & K) micronutrients(Fe, Mn, Cu & Zn), nitrogen fractions (NH₄⁺ & NO₃^- N), P-fractions (Al-P, Fe-p, Ca-P, Olsen P and Saloid –P), activity of soil enzymes (urease, dehydrogenase, acid and alkaline phosphatase) increases with conjuctive use of organic and inorganic nutrients rather individual application in crop production.
