原始语种摘要: Abstract(#br)Fertilization could promote phosphorus (P) cycling in soil; however, it is unclear how long-term fertilization regimes affect P-cycling-related microbial communities in different soil aggregates. In this study, we compiled promising strategies to evaluate the effect of 40-year long-term fertilization treatments on the P-cycling-related bacterial communities associated with different soil aggregates, of which P fraction and physicochemical properties were also measured. We found that both organic and mineral fertilization treatments increased the proportion of silt + clay (< 53 μm) and decreased the proportion of macroaggregate (250–2000 μm). Organic fertilization increased microaggregate (53–250 μm) proportion while mineral fertilization resulted in the opposite. The...
