Sources of loss were erosion, drainage, denitrifi-cation and fire. Erosion losses resulting from the natural geologic erosion cycle and fire were estimated at 0.15 lb/acre N annually and were based on data from a siltation survey of a water-storage dam. A lysimeter study and analysis of dam water showed that N in rainwater was not completely absorbed during passage through the communities, but that losses in drainage water were small.
