Table 2 Key results of a type III-ANOVA using satterthwait´s method applied to a linear mixed-effect model assessing the effect of drought (D) and grazing (G) ((A) Drought-Model), and nitrogen (N) and grazing(G) ((B) Nitrogen-Model) application on anion/cation- uptake simulated with PRS-probes in an experiment in South Africa in 2020. NumDF stands for numerator degrees of freedom, DenDF for denominator degrees of freedom (Satterthwaite method).
