B.A. Blackwell & Associates Ltd. was contracted by West Fraser Mills Ltd. to conduct foliar screening trials on young spruce (Picea glauca x engelmannii) (Sx) plantations on TFL 52 near Quesnel, British Columbia (BC). The site selected for the trial was fertilized in 2005. The objective of the current screening trial is to gather data to determine if re-fertilization of stands is supported by foliar micro- and macronutrient concentrations six years after the initial fertilization.
Research in BC and elsewhere in the world has shown that repeated fertilization of Sx can result in significant increases in growth and volume (Brockley 2004, 2010, Bergh et al. 2005). Determining if the nutritional status of previously fertilized stands can be improved by future applications is important to guide fertilization planning for young Sx leading plantations to alleviate mid-term timber supply issues. Samples were analyzed for foliar concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), boron (B), total sulfur (S) and inorganic sulfate (SO4).
