Description given on Youtube:
Cover crops in general are crops that are not intended for harvest and managed to maintain and enhance the sustainability of a production system by improving soil fertility, water quality, and lead to suppression of weeds, soil erosion, and pests. A summer short season cover crop could be defined as cover crop that is grown or managed for a short period of time, usually 45 to 60 days. Examples include buckwheat, cowpea, oats, oilseed radish, yellow mustard, and sorghum-sudangrass.
This video is a walk-through of various plants that can be used as a summer cover crop and how they can benefit the soil. For more information on sustainable vegetable production visit www.extension.iastate.edu/vegetablelab
