a Soil amino sugar content as necromass biomarker, including glucosamine from dead fungi and aminogalactose and muramic acid from dead bacteria. Data are presented as the means ± SD (n = 3). Δ means the difference between fertilization and non-fertilization (F–U). Capital letters indicate significant differences of fertilization effect in different climates, and lowercase letters indicate significant differences between in situ and transplantation (one-way ANOVA with Duncan’s multiple range test at p < 0.005). b Partial redundancy analysis (pRDA) differentiating the effects of soil geochemical attributes, live bacterial biomass, and dead bacterial amino sugar content on soil LC and RC.
