Data from: Impacts of harvesting methods on nutrient removal in Dutch forests exposed to high nitrogen deposition

Nutrient concentrations in tree compartments were assessed for seven major tree species in the Netherlands. Average nutrient concentrations in stems were based on measured concentrations in heartwood, sapwood and bark and estimated volumes and densities of these compartments. Similarly, average nutrient concentrations in branches were based on measured concentrations in coarse branches, fine branches and the bark of coarse branches and estimated volumes and densities of these compartments.

本数据集针对荷兰境内7种优势乔木树种的各树体组分（tree compartments）的养分浓度开展测定工作。树干的平均养分浓度基于心材（heartwood）、边材（sapwood）与树皮（bark）的实测养分浓度，以及上述组分的估算体积与密度计算得到。与之同理，枝条的平均养分浓度则以粗枝（coarse branches）、细枝（fine branches）以及粗枝树皮的实测养分浓度，结合上述组分的估算体积与密度进行核算。
