Table S5. Outcome of statistical tests for methane oxidation parameters, gene abundances, and physicochemical parametersof agricultural soils (0 -15 cm depth) and their upper-top and sub-top layers (0-7.5 cm depth and 7.5-15 cm depth, respectively). For continuous variables, Shapiro-Wilk and Levene's tests were performed to test for normality and homogeneity of variance, respectively, followed by either a one-way ANOVA or Scheirer-Ray-Hare test, and for binary variables, a χ²-test was performed, to test the effects of the effect of the organic treatment (organic-amended vs. unamended). Both the effects of the study sites ("Location") and the agricultural practice (no-tillage vs. tillage), and their respective interactions with the organic treatment, were also tested. Also, a pairwise comparison between soil layers was performed, using Tukey's HSD, Dunn's, or least-square means post-hoc test. Only p-values ≤0.05 are given.补充表S5。农业土壤（0~15cm深度）及其表层（0~7.5cm深度，亚表层为7.5~15cm深度）的甲烷氧化参数、基因丰度与理化参数的统计检验结果。对于连续变量，分别采用Shapiro-Wilk检验与Levene检验验证其正态性与方差齐性，随后执行单因素方差分析（one-way ANOVA）或Scheirer-Ray-Hare检验；对于二分类变量，则采用χ²检验，以评估有机处理（有机改良组 vs 未改良组）的效应。本研究同时检验了样地（"Location"）、农业耕作措施（免耕 vs 翻耕）及其与有机处理的交互效应。此外，采用Tukey HSD、Dunn法或最小二乘均值事后检验完成土层间的两两比较。仅列出p值≤0.05的结果。
