Impact of In-situ Paddy Straw Burning on Soil Enzyme Activity, Soil Microbial Population and Green House Gas Emissions in Sandy Loam Soil

The rice - maize cropping system is one of the predominant systems in Telangana state, which also produces large quantities residues, whose disposal a major problem. A quantity paddy straw burnt on farm to clear field for succeeding crop. On farm, significant amount burned prepare land subsequent Burning crop residue damages air and results loss biomass plant nutrients entire carbon. purpose study was investigate impact burning soil biological properties (enzyme activities, microbial population) know green house gas (GHG) emissions released due residue, under two tillage viz., no conventional tillage. Results indicated that there decrease population, dehydrogenase activity (41.52% NT 40.07% CT), acid alkaline phosphatase urease burning. It rise CO2, CH4 N2O 48 hours after can be concluded leads enzyme activities population. emissions. different genera has further studied by researchers.
