• Cultivar-specific methane emissions and yield-scaled greenhouse gas intensity responses to transplanting date: a case study in South Korea (2026) · Scientific Reports · doi

  There is a need to identify transplanting schedules that reduce methane emissions from flooded rice paddies without reducing grain yield. The effects of transplanting date on methane emissions and yield-scaled greenhouse gas intensity in rice cultivation are not well understood. The study aims to address this knowledge gap and contribute to the development of strategies for mitigating methane emissions from flooded rice paddies.

• Rice Cultivation Duration Is Associated with Changes in Potential CO2 Production, Q10, Enzyme Activity, and Microbial Diversity in Saline–Alkali Soils (2026) · Agriculture · doi

  The effects of long-term rice cultivation and warming on carbon cycling responses in saline-alkali soils are not well understood. There is a lack of studies investigating the impact of rice cultivation duration on potential CO2 production and microbial diversity in these soils. The relationships between rice cultivation duration, soil temperature, and CO2 production are not clearly understood.
