to Alfalfa Production H. J. EVANS AND E. R. PuRVis I T HAS become increasingly difficult to maintain productive stands of alfalfa on some New Jersey soils. In many instances the failure of the crop is due to known factors, such as injury from disease or insects, lack of lime, or deficiencies of P, K, B (7), or Mn (4). In many instances, however, crop failure cannot be attributed to any of these causes, indicating that some unknown factor is responsible for reducing both yields and longevity of the alfalfa stand on these soils. Investigators in Germany (3) and Australia (1) (5) have reported beneficial effects from applications of molybdenum salts upon the growth of alfalfa and other legumes. Accordingly, an investigation was undertaken to determine whether molybdenum deficiency is retarding the growth of alfalfa in this state.
