Abstract Soil aggregates store most soil organic carbon (SOC), but how does litter quality influence their formation? We hypothesized varying to facilitate differences in aggregate formation by altering the seasonal development of microbial biomass (MB) C and N, with MB driving a tropical sandy Thailand. Aggregate was studied long-term fallow experiment, receiving 10 Mg ha ?1 annual application...
