Appendix B. A table showing results of ANCOVAs for each site–substrate combination of the proportion initial N at all harvests with N fertilization as a main effect and the proportion initial mass remaining as a covariate.

A table showing results of ANCOVAs for each site–substrate combination of the proportion initial N at all harvests with N fertilization as a main effect and the proportion initial mass remaining as a covariate.

本表格展示了针对所有收获批次中各样地-基质组合（site–substrate combination）的初始氮占比（proportion initial N），以施氮处理（N fertilization）为主要效应（main effect）、初始残留质量占比（proportion initial mass remaining）作为协变量（covariate）所开展的协方差分析（ANCOVA）结果。
