FRDA Fertilization of Coastal Douglas-fir - Criteria for Site and Stand Selection

This FRDA Research Memo #224 outlines the crucial criteria for selecting sites and stands when fertilizing coastal Douglas-fir forests, emphasizing both the biological and economic rationale behind such silviculture. The authors confirm that nitrogen is the major limiting nutrient for immature Douglas-fir stands in coastal British Columbia, making fertilization a viable option for increasing timber supply. For maximum financial returns, fertilization should target medium- to high-quality sites that lack water deficits and possess low nitrogen concentrations, while ensuring that crop trees have adequate space for crown expansion to fully capitalize on the treatment. This document seeks to provide a framework for developing sound fertilizer prescriptions that maximize the economic benefit, particularly when coordinated with other forest management activities like commercial thinning.
