Ammonium nitrogen (NH₄-N); nitrate nitrogen (NO₃-N); C, N, P, and K are common abbreviations of elements. Asterisks marked the significant statistical difference (p < 0.05). Variance partitioning values of ordination axes were omitted here, and so did soil properties that are not strongly associated with soil microbial communities, but they are showed in Table S4.
