Abstract

•Long-term management influenced SOC and N, S & P concentrations in aggregates.•Practices with less soil disturbance increased SOC & nutrient contents in aggregates.•Silt-plus-clay fractions had higher SOC & nutrient concentrations than coarser aggregates.•Minimal impact of management on aggregate stability, and SOC and nutrient stocks.•Climate & soil type effects may have overridden management impact on SOM stocks.
