Cover crops can provide producers a variety of benefits including nutrient cycling , soil cover, nitrogen fixation and pollinator food sources. These cover crops come in many types, including grasses, legumes (mostly clovers) and brassicas (generally tillage radish and rapeseed). However, cover crops represent a “green bridge” throughout the fall and early spring that may facilitate the movement of insect pests and plant pathogens into above- and below-ground plant structures. Furthermore, cover crops may increase soil moisture and lower soil temperature compared with tilled fields at planting, resulting in more favorable conditions for seedling disease development.
