Comparison of K and Mg concentrations (mg/g) in leaves of M. bisulcata (Mb) and T. bifoliolata (Tb) seedlings in this and previous experiments. L1 and L3 are the first and third addition levels of K and Mg when the other element was not added. “–” indicates that no data were available. Experimental values are expressed as percentages (%) of the averages of the other studies’ values
