Rates of transfer of nitrogen in throughfall were measured in a Picea glauca (Moench) Voss forest in southwest Alberta, Canada. Total annual flux of N in throughfall was estimated to be 6.8 kg.ha-1.year-1. The highest rates of N deposition in throughfall occurred during the spring. The pattern of seasonal variation of N in throughfall suggested that different processes of N accumulation in and loss from the canopy may have been operating at different times of the year. Annual leaching of N from the canopy was estimated to be 4.09 kg.ha-1.year-1 and represented 24% of the total amount of N returned to the forest floor (leachates plus litter fall)
