Black Spruce Outplantings in Boreal Ontario
註釋To evaluate hexazinone's potential as a site preparation tool for establishing black spruce on productive upland boreal sites in northern Ontario, a cooperative study was initiated in 1979. Over 4 years, 5 experiments were begun. The study also sought to determine the delay required between chemical site preparation and planting. This report contains 5-year results from the crop-tree response portion of the study.
