Abstract
Continuous maize-wheat cultivation often leads to depletion of soil carbon and nitrogen reserves, affecting long-term productivity. A field study conducted during 2023-25 at ICAR-IIFSR, Modipuram evaluated organic, natural, and integrated nutrient management practices on soil carbon and nitrogen dynamics. Integrated nutrient management significantly enhanced soil organic carbon fractions, nitrogen pools, microbial biomass, enzymatic activity, and crop yields compared to control. Organic and natural inputs improved biological indicators but were less effective in nutrient buildup. Results indicate that integrated nutrient management offers a sustainable strategy for maintaining soil health and productivity in maizewheat systems.
