a, Development of water-stable aggregate size distribution, represented by four size fractions, as seen in the primary particle size of the subsoil without aggregates, the excavated subsoil pre-incubation (n = 3) and the development of the subsoil and soil mixtures after 30 days of incubation (n = 4) b, Changes in water-stable aggregate mean weight diameter (MWD) from the pre-incubation time point (n = 4); asterisks indicate significant differences in mean weight diameter from the excavated subsoil before incubation investigated using one-way ANOVA, with targeted post-hoc orthogonal contrasts restricted to predefined comparisons. Fig. 1 provides soil mixture clarifications. Error bars represent the mean ± one standard deviation. Figure created using BioRender.com.
