Spearman rank coefficient (r) for correlation between soil microbial communities, i.e., indicator operational taxonomic units (OTU) at a similarity threshold of 97% (OTU₉₇), and physicochemical soil properties, i.e., pH, electrolytic conductivity (EC), water holding capacity (WHC), and clay and sand content.

	BioEnv factora	r coefficient
Bacterial communities based on OTU97	Clay	0.438
Archaeal communities based on OTU97	EC	−0.0008

^aEnvironmental factors included pH, EC, WHC, clay, and sand.
