In order to assess the effect of balanced and imbalanced use of inorganic fertilizers and FYM in rice-wheat cropping system for twenty-nine years on physical soil quality indices after rice the observations were recorded from the continuing long-term fertility experiment initiated in 1984 at Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar. Combined use of inorganic fertilizer along with FYM significantly improved the bulk density (BD), water holding capacity (WHC), hydraulic conductivity (HC), mean weight diameter (MWD) and water stable aggregate (WSA) after rice in both the surface and sub-surface soil layer. |
