tailieunhanh - Effect of INM on soil carbon pools, soil quality and sustainability in ricebrown sarson cropping system of Kashmir Valley

Integrated nutrient management system (INMS) gained importance not only in increased yield of crops but also in maintaining the soil health and fertility. Keeping these in views a field experiment was conducted at Mountain research centre for field crops Khudwani (SKUAST-Kashmir) during 2013 (in progress since march 2008) to study the Effect of INM on soil carbon pools and soil quality in rice-brown sarson cropping system with different treatment combinations. Significant build-up in soil fertility in terms of alkaline KMnO4-N, Olsen-P, NH4OAc-K and CaCl2-S as well as SOC pools namely, total organic carbon (TOC), Walkley and Black organic carbon (WBC), labile organic carbon (LBC) and microbial biomass carbon (MBC) were maintained under FYM and integrated nutrient management involving FYM and NPK than unfertilized control plot in 0-15 and 15-30 cm soil depths. |
