Biomass and potential nutrient removal by harvesting in short-rotation plantations

Biomass and potential nutrient removal by harvesting in short-rotation plantations

Data on standing biomass, mean annual increment of carbon stock, and nutrient
accumulation in 40 industrial plantations at 21 sites in 11 countries are summarised.
Aboveground biomass and mean annual increment of carbon near the harvest age, of
these plantations ranged from 44 to 324 t ha-1 and from 3.1 to 22.9 tC ha-1 yr-1,
respectively. Plantations managed on a short rotation are expected to accumulate
carbon rapidly. However, there are large variations of biomass accumulation depending
on site conditions. There is concern about the potential decrease of productivity
caused by nutrient loss by intensive and repeated harvesting. It is important to
determine the nutrients removed and conserve them as much as possible to prevent
productivity loss and for sustainable management of industrial plantations. Careful
management of the nutrient cycle through residue retention and fertiliser application is
necessary to maintain high productivity.
