Effect of Organic and Conventional System of Nutrient Management in Basmati-Wheat Sequence on Soil Properties

Effect of organic and conventional system of nutrient management for six and half years in basmatiwheat sequence was studied on general soil properties and plant available macronutrients. Application of inorganic fertilizers (N, P and K) resulted in significant increase in mineral N, available P and available K, compared to unfertilized control. Among organic sources, farmyard manure (FYM) applications showed superior impacts on soil mineral N, available P, bulk density and porosity compared to rice straw compost and vermi-compost. Integrated use of organic and inorganic sources of nutrients favourably impacted these soil properties to a greater extent than application of either of the sources alone.
