Figure 2. Overall structural changes of bacterial communities (A) and fungi communities (B) from sequencing data as influenced by fertilizations.

The clustering was based on the weighted distance tree in Unifrac. CK, Control; P, 60 kg P ha⁻¹; N, 100 kg N ha⁻¹; NP, 60 kg P ha⁻¹ plus 100 kg N ha⁻¹; M, 4,000 kg sheep manure ha⁻¹. Lowercase letter “u” after treatment represented samples from 0–10 cm soil layer; “d” represented samples from 10–20 cm soil layer.
