The effect sizes of cumulative C mineralization of forest and paddy soils by N addition. A and B are the forest and paddy soils, respectively. BS, MA, MI, and MF denote bulk soil, macroaggregate (2000–250 μm), microaggregate (250–53 μm), and < 53-μm fraction. N1, N2, and N3 are 50 μg N g⁻¹, 100 μg N g⁻¹, and 150 μg N g⁻¹, respectively
