This study investigates the impact of in situ rice straw incorporation on soil nutrient dynamics during the 2021-22 kharif season in Sindewahi, Maharashtra. Using a Factorial Randomized Block Design, two microbial treatments-PDKV decomposer and Resident Isolates-were tested along with three nutrient management levels. The data revealed that during decomposition of in situ incorporated rice straw total N, total P and total K were increased. The data of the present experiment revealed that the total C were gradually decreased in the rice straw treated with PDKV decomposer and resident isolates. Whereas total, P, and K were slightly increased in soil in situ incorporated with rice straw and treated with PDKV decomposer and resident isolates indicating progressive increase/decrease in the elemental composition. The magnitude of decrease in the total C was 0.057% during decomposition of crop residue in soil. Among total N, P and K, the magnitude of increase was higher in case of total K which was 0.00082% during decomposition.
