Physicochemical properties and differential metabolites of soil samples after 4 years of simulated precipitation: (a) Physicochemical factors with significant differences; (b) correlation network diagram of microorganisms, metabolites, and physicochemical factors; (c) redundancy analysis of microorganisms and physicochemical factors; and (d) differential metabolite heatmap. Note Hum: soil humidity; pH: soil pH; TC: total carbon; Tem: soil temperature; and TN: total nitrogen. (a)–(d) denotes significance, the same letter indicates no significant difference (P > 0.05), and different letters indicate significant difference (P < 0.05)
