Nitrogen is the most abundant atmospheric element and a major nutrient required for plant and tree growth. The vast majority of nitrogen in forest soils and tree biomass is fixed from the atmosphere by soil micro‐organisms. Although the vast majority of nitrogen in most forest ecosystems is held in soil organic matter, some sites contain larger portions in live biomass and may therefore be susceptible to reductions in long‐term site productivity …more
