Soil bacterial richness was associated with multiple soil properties. Relationships between bacterial ASV richness and six selected soil properties (A. pH, B. SOM, C. water content, D. \({\text{PO}}_{4}^{ - 3}\) content, E. MicC and F. microbial C:N, full results can be found in Additional file 1: Table S9). Results of linear models are given for each regression analysis within each graph and standard errors are indicated as grey shaded areas around the trend lines
