Total K (a), Mg (c), Fe (e) and Zn (g) and available K (b), Mg (d), Fe (f) and Zn (h) in soils (mg kg−1) under the different biocrust cover (low biocrust vs. high biocrust), warming and rainfall exclusion levels evaluated 7 years after the beginning of the experiment: control (Amb.), rainfall exclusion (Rain), warming (Warm.) and rainfall exclusion and warming (RxW) (box and whisker plots, n = 5).
