Effect of straw incorporation on methane emission in rice paddy: conversion factor and smart straw management

Abstract: Straw incorporation is strongly recommended in rice paddy to improve soil quality and mitigate atmospheric carbon dioxide (CO 2), via increasing soil organic carbon (SOC) stock. However, straw application significantly increased methane (CH 4) emission during rice cultivation, and then its incorporation area was not expanded effectively. To find the reasonable straw management practice which can reduce CH 4 emission without productivity damage, the effect of straw incorporation season and method on CH 4 emissi… Show more

“…According to the actual circumstances of the rice planting areas, to carry out appropriate supporting cultivation measures, such as green manure cropping winter cover and protective lime amendment measures can be implemented. Additionally, measures such as the promotion of returned straw and intermittent irrigation, and the promotion of soil testing formulas and precise fertilization and the development of carbon reduction emissions of rice planting patterns can be expanded ( Jiang R. et al, 2017 ; Jiang et al, 2018 , 2019 ; Song et al, 2019 ; Qian et al, 2022 ). The author thinks intelligent rice technology should include three modules, namely, the rice productivity technology (adaptive cultivation technology), soil organic carbon sequestration technology and paddy GHG emissions reduction technology.…”

“…2). At the early rice growth stage, CH 4 is emitted at a lower rate, but its flux steadily increases with plant growth and development of anaerobic soil conditions (Ali et al, 2009a;Kim et al, 2015;Haque et al, 2016;Jeong et al, 2018;Song et al, 2019;Lee et al, 2020a,b;Song et al, 2021).…”
