This new extension bulletin is an excellent resource for growers interested in producing organic alfalfa, both irrigated and dryland. Alfalfa provides an excellent transitional crop for those interested in organic production of other crops as well. This guide includes a great deal of information on managing weeds, pests and diseases, and includes a small section on economics.
