Notes:$k$: Number of selected fields per treatment and country $i$; standard deviation in parentheses. The three columns of $p$-values indicate the results of the Mann–Whitney-U test. ${\chi }^2$ and the corresponding $p$-value indicate the results of the Kruskal–Wallis test, testing for differences between the three frames.
