Other claims from this paper (11)
- Intervention effect Nitrogen alone increased height, diameter, and basal area growth.
- Intervention effect Phosphorus combined with nitrogen increased height, diameter, and basal area growth.
- Intervention effect Adding potassium to nitrogen and phosphorus did not produce an additional growth response.
- Observation Growth responses were greatest in the first two years, while height and diameter increases lasted four to five years.
- Intervention effect First-year maximum growth rates occurred with 112 kg N/ha and 49 kg P/ha.
- Intervention effect Sustained responses in later years required 224 kg N/ha and 49 kg P/ha.
- Observation Saplings had greater absolute basal area response than seedlings.
- Intervention effect Nitrogen fertilization raised foliar nitrogen from 2.51 to 3.94% in year one.
- Observation Foliar nitrogen then declined to control level by year four.
- Intervention effect Phosphorus fertilization raised foliar P from 0.12 to 0.21% in year one, with further increases through year five.
- Intervention effect Potassium fertilization raised foliar K from 1.01 to 1.21% over five years, with year-to-year variation.
