Forest biomass harvesting: soils and nutrient sustainability

This presentation outlines steps taken to determine the nutrient sustainability of forest biomass harvesting. This is done by balancing nutrient losses due to harvesting and soil leaching with nutrient supplies via atmospheric deposition and soil weathering. The emphasis is on primary nutrient supplies and losses, instead of secondary nutrient cycling processes. Forest managers have taken note of this approach, as a means to determine the suitability of forest stands for biomass harvesting, in areas where soils are not too wet, too steep or too shallow.
