Storage and remobilization of nitrogen (N) were studied in ash trees (Fraxinus excelsior) under both field and greenhouse conditions. Experiments in the greenhouse providing 15N labelled fertilizer to the trees showed that the major quantity of N remobilized during subsequent spring was from the roo...
