Evaluation of “Green Manure” Rotational Strategies for Potatoes in Upstate New York

Abstract

North Country potato growers are looking at rotational crops they are unfamiliar with. Sudangrass has been successfully employed throughout the state as an excellent way to increase organic matter, break up soil hard pans and decrease soil pathogens. In recent years, crops in the mustard family used as green manure have shown soil benefits as well. We looked at yellow mustard, oilseed radish and sudangrass as green manure treatments in a rotation with potato.
