Biomass and nutrient cycling of a highly productive Corsican pine stand on former heathland in northern Belgium

Biomass and nutrient cycling were examined in a 62-year-old highly productive Corsican pine stand ( Pinus nigra Arn. ssp. laricio Poiret) growing on a coarse and dry sandy soil with low exchangeable nutrient pools. Total aboveground biomass was estimated at 240 tons dry weight per hectare of which 201 tons concerned boles. The belowground biomass amounted to 46 t ha -1 (16 % of total standing biomass). The current annual volume increment was estimated at 20.6 m 3 h -1 year -1 . Root study emphasized the role of the rooting depth as an important growth factor. Calculated uptake rates for N, P,...
