The study looked at how different ways of farming rice affect the release of carbon dioxide and the health of the soil. They found that using less intensive farming methods and adding rice straw to the soil can help reduce carbon dioxide emissions. The researchers discovered that the soil had more carbon and nutrients when minimum tillage was used, leading to lower carbon dioxide emissions. Adding rice straw to the soil also improved soil fertility and nutrient availability for crops. Overall, using minimum tillage and incorporating rice straw can help reduce carbon dioxide emissions from rice fields and improve soil health.
