Acidification and Nitrogen Eutrophication of Austrian Forest Soils

Table 3

critical loads (CL) for acidification (kg ha⁻¹ yr⁻¹) and eutrophication (kg ha⁻¹ yr⁻¹) of the Austrian forested area. CL-acid_max (S): critical load of S assuming an exclusion of N; CL-acid_max (N): critical load of N assuming an exclusion of S; CL-eut_nut (N): CL for eutrophication according to the mass balance; CL-eut_emp (N): empirical CL for eutrophication for Austrian forest types according to [26] ECE (2010).
