Abstract
Nitrates in Kentucky soils were determined mainly in the fall, when wheat was seeded, to ascertain the relationship between nitrate production and wheat yields. Averages of results of the last 3 yrs. show a fairly close relationship between nitrates and yields, which probably indicates the relationship in the future; but when results of the first 2 yrs. are included the relationship is shown to be only very general and to have no correlation at numerous points.
