Abstract

The nutritional sustainability of a short-rotation Eucalyptus grandis plantation system was evaluated in a trial located at Karkloof, KwaZulu-Natal, South Mrica, by determining nutrient pools and fluxes. Nutrient pools in the forest floor and biomass (above- and below-ground) were assessed by destructive sampling. The size of nutrient pools in the soil that approximate to readily available and potentially available fractions was estimated from chemical extractions. An approximate nutrient input-output budget was constructed.
