There is a highly significant positive correlation between MBC and organic P ( r = 0.918, p < 0.001), and a strong correlation between soluble C and organic P ( r = 0.905, p < 0.001).

In contrast, the TOC content of the bottom soil (5–15 cm) decreased compared to the initial soil, although its soluble C and MBC showed an increasing trend.
