Number of OTUs significantly correlated with environmental variables in farmland and grassland in the top 200 dominant OTUs^a

Soil	pH	EC	TN	SOM	TP	Clay	Silt	Sand	MAP	MAT	NDVI
Farmland	6	29	47	38	39	13	12	13	43	84	60
Grassland	2	43	44	38	21	5	22	21	50	0	53

^aPearson’s P value is adjusted by the Benjamini-Hochberg correction. When the corrected P is less than 0.05, the correlations between relative abundances of OTUs and environmental variables are significant. For abbreviations, see Table 1.
