My notes from the Upper MIdwest Orga. Farm. Conf. last spring show that using yellow or white mustard as a cover crop can be a good predecessor for potatoes. Planting the yellow mustard in the fall results in winter kill by Dec. Then the decomposing mustard puts out a powerful gas that suppresses soil borne pathogens.
Not a good practice if you intend to follow with another brassica in the spring, tho. Dorothy __________________________________________________ Do You Yahoo!? LAUNCH - Your Yahoo! Music Experience http://launch.yahoo.com
