The Role of Ferric oxide in Reducing Carbon Dioxide Emissions from Rice cultivation: A Pot Greenhouse Experiment

Rice cultivation significantly contributes to greenhouse gas emissions, particularly carbon dioxide (CO₂), due to plant respiration and soil microbial activity. This study investigates the potential of ferric oxide (FO) supplementation as a mitigation strategy for CO₂ emissions in rice paddies. A controlled pot experiment was conducted to assess the effects of FO application and its interaction with time after planting on CO₂ emissions and rice yield. Results indicate a peak in CO₂ emissions around 40 days after planting, with FO supplementation reducing emissions in a dose-dependent manner. Additionally, the interaction between FO application and plant growth stages significantly influenced emission patterns. FO-treated soils exhibited lower CO₂ fluxes while maintaining rice productivity, suggesting its potential role in modifying soil biochemical processes. These findings provide new insights into CO₂ dynamics in rice cultivation and highlight FO supplementation as a promising approach for mitigating emissions. Further research is warranted to optimize FO application strategies and assess long-term environmental sustainability in diverse rice-growing conditions.
