Fig 9. RDA based on the relative abundances of the top 20 bacterial orders and selected soil properties of the soil samples collected from the treatments and CK.

Selected soil chemical properties were significantly correlated with variations in the selected bacterial (A) and fungal (B) genera according to the Monte Carlo test (p < 0.05). TN: total nitrogen, OM: organic matter, AP: available phosphorus, AK: available potassium.
