Abstract
For many years it has been recognized that the two major limiting factors to alfalfa (Medicago sativa) growth in the upper Midwest are soil pH and exchangeable soil potassium (Brown, 1928; Hull, 1934; Lanyon and Griffith, 1988). Recent research affirms the benefits of raising pH to near neutral by adding lime to fields where alfalfa is to be grown in Wisconsin (Peters and Kelling, 1989; Peters and Kelling, 199 7).
