What kind of crop rotation should be used?
Annual green manure crops like peas, lentils and chickling vetch work well in any rotation that normally includes pulse crop varieties or fallow periods. To avoid disease and weed control problems, do not grow another pulse crop variety before or after a green manure in rotation. Cereals and oilseeds are recommended. Sweetclover is a biennial, so growing it under a cover crop that is less competitive – usually a cereal (wheat or oats) – will reduce competition between crops and increase the viability of the sweetclover stand in the following year. It is important to incorporate the sweetclover early as a green manure, in order to avoid high moisture use by the crop.
