Abstract: The present investigation is an account of soil quality parameters as influenced by paddy straw decomposition and its subsequent inoculation with microbial consortia. Such information may prove useful for fast decomposition of paddy straw and improve soil carbon content and it may provide an option to combat crop residue burning because time difference between rice harvest and wheat sowing is only 15-30 days, not sufficient for decomposition and eventually clean field. Moreover residue removal from field for off-situ composting is a labour intensive process. So there is a need to find out an alternative way to address this issue. The study revealed that amongst treatments there was no significant difference observed in terms of pH and EC of the soil. However, the decomposition of paddy straw along with Aspergillus spp. + Bacillus spp.+ Streptomyces spp. (T8) resulted in significant increase in organic carbon contents of the soil from 0.63 % to 0.68%. It is apparent from result that integration of straw with consortia resulted significantly the maximum content of available and potassium content in soil as compared to the treatment which receive single consortium of fungal, bacterial or actinomycetes. The phosphorus content of soil was not increased significantly with the use of paddy straw + Aspergillus spp.+ Bacillus spp.+ Streptomyces spp. consortia. The Easily Extractable and Total Glomalin Related Soil Protein after 60 days of residue decomposition, in moist soils were not affected by straw decomposition with microbial consortia. Addition of straw along with Aspergillus spp. + Bacillus spp. + Streptomyces spp. consortia increased CO2 production as compared to the control.
