Conceptual model on the expected causal relationships between environmental variables, soil properties and potential soil net Nmin to estimate realised soil net Nmin. The conceptual model is based on hypotheses derived from the literature and our linear mixed effects model results (see Table 1 for hypotheses and references). Tvar = temperature variability, T.q.wet = temperature of the wettest quarter
