- Intervention effect Nutrient addition increased stand volume growth from 2 to 7 m /ha/year on unthinned plots.
- Intervention effect Fertilizer raised volume growth on thinned plots to 5 m3/ha/year.
- Intervention effect Thinning increased tree-level foliage biomass and growth efficiency.
- Intervention effect Nitrogen, sulfur and boron additions improved tree and stand growth through greater foliage biomass and growth efficiency.
- Association Fertilization and thinning had additive growth effects.
- Observation More fascicles contributed more than fascicle weight to foliage biomass responses.
- Observation Under thinning, branch number and foliage per branch contributed nearly equally to foliage biomass increase.
- Intervention effect Treatments had no effect on foliage biomass at the bottom of the live crown or its position.
- Observation The number of cohorts declined toward the base of the live crown.
