Soil-atmosphere fluxes of CO2 and CH4 in annual and perennial cropping systems in southern Sweden
Annual cropping systems dominate agricultural grain production, but have been linked to several key environmental issues, such as loss of biodiversity and pollution of groundwater. Newly developed perennial grains may offer solutions to some of those problems. Their longer roots and growing seasons theoretically enable them to act as sinks of atmospheric carbon. This study set out to compare soil-
