Sugar Beets ^ OME of the alkaline soils of Michigan are deficient O in manganese for wheat, oats, barley, sugar beets, and beans. Characteristic symptoms of deficiency develop on these plants when the supply of available soil manganese becomes too low. In detail, the symptoms vary in the different crops, but in all cases there is a loss of the green coloring matter (chlorosis). As this is true in the case of certain other deficiencies, for instance nitrogen, it is desirable to be able' to confirm the symptoms by testing for manganese in the fresh "plant tissue. It was thought also that it might be possible to detect dangerously low levels of mangaSchroeder farm: nese before the symptoms appear.
