Fig. 3
Combined effects of drought (yes: D+; no: D−) with grazing (yes: G+; no: G−) on plant-available cations and anions (measured as their uptake 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 a significant difference at p<0.05. If applicable, letters in brackets refer to an alternative threshold level of p<0.1.
