Fig. 2
Combined effects of nitrogen application (yes: N+, no: N−)) and grazing (yes: G+, no: G−) on the uptake of macro- and micronutrients by resin membranes simulating plant roots. The nutrients: nitrates (NO3−–N), ammonium (NH4+–N), calcium (Ca), magnesium (Mg), potassium (K), phosphorus (P), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), and sulphur (S). All units are in µg/10cm2/160 days. Different letters indicate significant differences at p<0.05. If applicable, letters in brackets refer to an alternative threshold level of p<0.1.
