Inasmuch as oat hay containing potassium nitrate in excess of 1.5 percent is considered unsafe as cattle feed, some of the losses sustained in Sully, Potter, and Walworth counties may have been due to excess nitrates present in the cornstalks. Since nitrates or other nitrogen fractions (e.g. the alkaloids) are frequently associated with forage poisoning, it seemed advisable to further investigate the nitrogenous constituents of the corn plant. It is the purpose of this paper to present data collected at this laboratory relative to the changes in the nitrogenous constituents of field grown corn plants throughout the period from the seedling stage to maturation, and to note the subsequent effects of weathering upon corn stalks left standing in the field.
