An understanding of the mechanism of tree and stand response to fertilization is needed to refine our fertilizer prescription and response prediction for different site and stand conditions. This paper discusses: 1) fertilizer use in relation to stand thinning, citing results from the Shawnigan Lake installation as an example; and 2) the relative importance of foliage area and efficiency in fertilizer response and how this information can be used to explain, in part, the response pattern with time, as well as thinning-fertilization interactions and refertilization effects. The influence of environmental conditions on growth response to fertilization is discussed with emphasis on soil water deficits.
