e0“Basal area increment significantly (p < 0.05) increased in response to N fertilizer for 3, 6, 11, and 13 years after applications ceased, in treatments that received 252, 504, 1008, and 1512 kg N•ha −1 , respectively.”

- Observation Volume increment changed from a quadratic to linear response to nitrogen level.
- 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.
