- Intervention effect Basal area increment rose significantly for 3 years at 252 kg N per hectare.
- Intervention effect Highest nitrogen rate increased standing biomass by 42%.
- Observation Four-fifths of the biomass increase occurred in stems.
- Intervention effect Nitrogen fertilizer prolonged the increase in foliage biomass.
- Observation Stand nitrogen retention persisted although distribution changed.
- Observation Stand nitrogen gain beyond fertilizer inputs resembled estimated atmospheric input.
