　　No-till is practiced for various environmental and economic reasons,but the absence of soil loosening by tillage affects soil structure and associated soil functions such as gas transport and crop growth.The main objective of this study was to investigate the impact of two decades of notill on soil gas transport properties in the Oberacker long-term field experiment in Switzerland.
