Title
Response of thinned, immature lodgepole pine to nitrogen and boron fertilization
R. P. Brockley Canadian Journal of Forest Research 1990. doi:10.1139/x90-075
Other claims from this paper (8)
- Association Subacute boron deficiency may reduce nitrogen fertilizer response.
- Intervention effect Combined nitrogen and boron significantly improved 3-year mean height increment versus nitrogen alone.
- Intervention effect Combined nitrogen and boron significantly improved 3-year mean volume increment versus nitrogen alone.
- Intervention effect Boron additions elevated and maintained foliar boron concentrations for 3 years.
- Intervention effect No foliar toxicity was observed after boron application.
- Association First-year fascicle weight and second-year branch elongation predicted later stem volume response.
- Mechanism Nitrogen and nitrogen plus boron may have induced marginal sulphur deficiency.
- Recommendation Authors recommend boron with nitrogenous fertilizer where foliar boron is below 15 ppm.
