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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
