Abstract: There are numerous direct and indirect adverse impacts caused by residue removal on ecosystem, including depletion of the soil organic carbon (SOC). Important direct impacts of residue removal are low input of carbon (C) biomass, reduction in nutrient / elemental cycling and decrease in food / energy source for soil biota along with the attendant decline in soil quality. To overcome this, different rice straw management options and its effect on soil available nutrients were studied. Rice straw incorporated without and with additives (25 kg additional N ha-1 as basal, bio-mineralizer (2 kg t-1 rice residue), cow dung slurry (5 %) as individual, combination of two and combined application of all. Among this, Incorporation of straw with application of 25 kg additional N ha-1 as basal + bio-mineralizer + cow dung slurry registered the highest soil available N, P, K and micro nutrients at tillering, flowering and post-harvest stages.
