A study was made to evaluate the influence of chlorine and other constituents on tobacco leaf-burn (capacity to hold fire when ignited). Samples of tobacco plants and soil at different depths were taken from 33 fields located in the 2 tobacco growing districts in Wisconsin in 1952, and the data concerning chemical composition and leaf-burn were subjected to statistical analyses. The amount of chlorine taken up by the crops was most closely correlated (r = 0.79) with that found in the 0 to 12-inch layer of soil. On the average, about ½ of the chlorine found in this layer was taken up by the crops. A highly significant coefficient of multiple correlation, R = 0.80, was found for the relation between log leaf-burn and the contents of chlorine, sulfur, nitrogen, and potassium of the tobacco leaves. A comparison of the standard coefficients indicated that potassium is about 1.2 times more beneficial to leaf-burn than either chlorine or nitrogen is detrimental, and about 2.4 times as beneficial as sulfur is deterimental.
