Methane in rice agriculture: A review

This review gives an account of mechanisms of methane production and emission from flooded paddy fields. Future methane emission scenarios show that methane emissions in 2030 in India are projected to reach 24.4 Tg (reference scenario), 21.3 Tg (medium mitigation scenario) and 17.6 Tg (strong mitigation scenario). Morpho-physiological parameters (leaf number, tiller number and plant biomass) are reported to influence methane emissions. Use of nitrification inhibitors (prilled urea and nimin) are reported to be suitable methane mitigation options.
