Extended Data Fig. 1: Soil abiotic profiles and precipitation records.

(a) Hierarchical clustering of soil types based on their abiotic properties. The heatmap shows the z-transformed values of the edaphic variables included in the analysis. (b) Daily precipitation at each of the three field sites preceding, during, and after soil harvesting. Dotted vertical lines mark the dates of soil sample collection. (c) Gravimetric soil moisture content over time across soil types. Points correspond to individual microcosms, and trend lines represent the mean moisture content at each time point. Color indicates whether replicates underwent rewetting or remained dry.
