TAILIEUCHUNG - Soil amendments as GHGs curtailers in rice fields

Rice cultivation is being focused as a prime contributor to climate change due to the release of greenhouse gases into the atmosphere. In aspect to study the reduction of the GHGs emission, experiment trial was conducted with eight different soil amendment combinations viz., recommended dose of Fertilizers (RDF), fly ash, Biochar, Gypsum, Silica Solubilizing Bacteria (SSB), fly ash + SSB, Biochar + SSB, Gypsum + SSB. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 12 2019 Journal homepage http Original Research Article https Soil Amendments as GHGs Curtailers in Rice Fields N.

In aspect to study the reduction of the GHGs emission experiment trial was conducted with eight different soil amendment combinations viz. recommended dose of Fertilizers RDF fly ash Biochar Gypsum Silica Solubilizing Bacteria SSB fly ash SSB Biochar SSB Gypsum SSB. Gas collection was done at different crop growth stages using open bottom chambers and analyzed with Shimadzu GC-2014 gas chromatograph. Methane emission was observed less in applications of Fly ash kg ha Fly ash SSB kg ha and Gypsum SSB kg ha . Low levels of nitrous oxide emission were seen in applications of Fly ash SSB kg ha Gypsum SSB kg ha and Fly ash kg ha . Higher nitrous oxide and methane emission was found with the treatments of RDF SSB Biochar Gypsum and Biochar SSB. From the study it was concluded that application of fly ash SSB and fly ash did reduce the GHGs emissions on higher percentage over the application of other soil amendments in rice field.
