Matrix of Mann-Kendall Tau statistics of the convergence/divergence test between the trajectories of the four plots labelled according to their previous use as well as for the experimental treatment (fertilised and non-fertilised). Negative values indicate convergence, and positive values indicate divergence. Below the diagonal, P-values are given. Significant values of the test statistic are in bold. For details on the statistical approach, see³⁶.
