“…In accordance with effects discussed in the previous section, additions of soil-derived POM resulted also in higher molar (N 2 O + N 2 )-N/CO 2 -C ratios than MOM additions, the ratio being maximum for the Fu soil with POM addition (Table 5). This supports the idea that the product ratios of denitrification respond to the chemical composition of WEOM (Surey et al, 2020b) and again indicates a higher quality and use efficiency of WEOM derived from plant residues than from MOM.…”

“…Due to the small WEOC contents of the Fu POM, rapid depletion of such readily available C compounds could be the reason for the declining effect of added Fu POM on cumulative N 2 O + N 2 already after 6 h, when the maximum was reached (Figure 2B). Thus, as already shown in a previous study (Surey et al, 2020b), potential denitrification depends not only on the plant residues' content of WEOM but also on its chemical composition (e.g., C/N ratio, aromaticity, shares of sugars, and organic acids). Consequently, when predicting denitrification potentials of different soils, the quantity of WEOC as well as its quality needs to be considered.…”
