Soil macroaggregates and organic-matter content regulate microbial communities and enzymatic activity in a Chinese Mollisol

The formation and turnover of macroaggregates are critical processes influencing the dynamics and stabilization of soil organic carbon (SOC). Soil aggregate size distribution is directly related to the makeup and activity of microbial communities. We incubated soils managed for >30 years as resto...

Zusammenfassung:The formation and turnover of macroaggregates are critical processes influencing the dynamics and stabilization of soil organic carbon (SOC). Soil aggregate size distribution is directly related to the makeup and activity of microbial communities. We incubated soils managed for >30 years as restored grassland (GL), farmland (FL) and bare fallow (BF) for 60 days using both intact and reduced aggregate size distributions (intact aggregate distribution (IAD)
