Abstract: There is uncertainty around the ability of many planted forest soils to provide nutrients in the long term and limited suitable data available from longterm rotation length trials to address these concerns. Improved genetic and silvicultural management over the past decades have greatly improved forest productivity in New Zealand and may have the potential to mask reductions in soil nutrient supply. The nutrient balance model NuBalM offers the opportunity for ‘precision nutrient management’ for planted forests over multiple rotations for long-term nutrient sustainability.
