The findings from this study looking at organic conservation tillage systems (OCT) show that cover crops can enhance weed suppression, and hence crop productivity through physical interference and allelopathy and also impacts soil quality, fertility, and soil moisture. This points to the need for policies that support transitions to diversified farming systems, OCT, and agroecological practices.
