Microaggregate-associated C and N stocks were higher in no tillage compared with conventional tillage. Microaggregates comprised 13% of the total aggregates. Macroaggregates on average accounted for 48% of the total aggregates. Crop rotation and N fertilization did not contribute to the pool of C and N sequestration.
