The response of cumulative C mineralization of aggregates to N addition in forest (A) and paddy (B) soils during the entire incubation period (90 days). BS, MA, MI, and MF denote bulk soil, macroaggregate (2000–250 μm), microaggregate (250–53 μm), and < 53-μm fraction. N0 (without N addition, the control), N1 (50 μg N g⁻¹), N2 (100 μg N g⁻¹), and N3 (150 μg N g⁻¹). F is the forest soils and P is the paddy soils. A and N denote the soil aggregates and N addition
