Rice-based crop rotations against global warming

Global warming is mainly due to the increase of carbon dioxide (CO2) concentration in the atmosphere. Agriculture highly influences atmospheric CO2 because plants and soils can sequester CO2 or release CO2. Researchers are thus trying to identify cropping practices, such as conservation tillage, that sequester CO2 in plants and soils in order to decrease atmospheric CO2 levels. Agronomists Motschenbacher et al. studied for the first time daily soil surface CO2 in rice-based crop rotations with corn, soybean, and winter wheat.
