Nutrient contents of canopy throughfall precipitation (TFP) from fertilized and unfertilized crops were analyzed and compared to determine the importance of fertilization on this source of nutrients in runoff. Continuous barley, corn, oats, rye, and wheat plots, that had been unfertilized since 1941 and divided and half fertilized since 1959, were studied. TFP soluble PO/sub 4/, total PO/sub 4/, and soluble K amounts were usually larger from fertilized plots in comparison to unfertilized ones but the differences usually were not significant. NH/sub 4//sup -n/ and NO/sub 3//sup -n/ may have been adsorbed from precipitation by corn canopies.
