Long-term N addition and liming did not affect bulk SOC content and stocks but lead to redistribution of C into water stable aggregates. Long-term N fertilization caused soil acidification and reduced mean weight diameter. Long-term N fertilization increased micro-aggregates and SOC stored in them. Long-term liming did not affect WSA, and C stored in them. Liming improved aggregation and increased C associated with large macro aggregates when co-applied with N fertilizers.
