Description

Distribution of N, P, K, Ca, and Mg in the tree, understory, forest floor, and mineral soil horizons was determined for two series of postfire foerest stands in northeastern New Brunswick. Twelve pure jack pine stands (Pinus banksiana Lamb.) and 11 mixed hardwood stands aged 7-57 years were examined. Regression equations relating aboveground tree nutrient content to diameter for eight tree species were calculted. The jack pine stands demonstrated variable stand density, but adjustment to normal stocking produced a sigmoid nutrient accumulaton pattern in the tree layer during the 60-year period. Nutrient accumulation in the tree layer of both series of stands closely approximated biomass accumulation. Understory nutrients formed a significant fraction of the total aboveground pool, particularly in the younger stands. Organic and mineral soil horizon nutrients were found to be highly variable for both series of stands; this was postulated to be a result of the fire origin of the stands, with varying fire intensity and postfire conditions resulting in different nutrient losses from the site.© National Research Council of Canada, NRC Research Press.
