Other claims from this paper (7)
- Intervention effect Fertilization produced large growth increases in Populus deltoides.
- Association A strong clone-by-fertilizer interaction occurred for diameter, height and volume growth.
- Intervention effect Fertilization reduced wood specific gravity.
- Recommendation Cottonwood should be selected in the nutritional environment in which it will grow.
- Intervention effect Clones performing poorly without fertilizer frequently excelled with fertilizer, with the reverse occurring in several instances.
- Recommendation Selection specifically for fertilizer response may be possible in tree improvement programs.
- Recommendation Fertilizer response in potentially genetically biased experimental populations should be interpreted cautiously.
