The effects of an excess input of nitrogen on terrestrial ecosystems may include changes in vegetation, damage to forests, and pollution of groundwater with nitrate. Critical loads (deposition levels) for nitrogen related to these effects can be derived by empirical data, steady-state soil models and dynamic soil-vegetation models. Examples of the various approaches are given with a discussion of the advantages and disadvantages for the mapping of critical loads.
