- Intervention effect In 1997, N rate and fertigation frequency did not affect trunk diameter.
- Intervention effect In 1997, N rate and fertigation frequency did not affect leaf N.
- Observation Trees took up no more than 6% of applied N in 1997.
- Observation About 50% of fertilizer N uptake was in leaves in 1997.
- Observation Trees grew much more rapidly in 1998.
- Intervention effect Leaf N was significantly higher in fertilized plots than controls in 1998.
- Observation No more than 25% of fertilizer N was taken up in 1998.
- Observation About 60% of fertilizer N uptake was in leaves in 1998.
- Recommendation The authors recommend no N application in the first growing season.
- Recommendation The authors recommend modest N rates of 68 to 136 g/tree in the second season.
