Hence the average oxidation state of carbon in acetic acid is 0. 2c): mean soil CH4 uptake rate was 0.790.09mg CH4m2d1 in a SOC content range from 0 to 20gkg1, but it was more than 3 times higher (2.980.32mg CH4m2d1) when SOC content ranged from 60 to 100gkg1. 9, 543548 (2016). Let us assume that the oxidation number of Carbon is x. Here, using in-situ observations, global meta-analysis, and process-based modeling, we provide evidence that SOC constitutes an important variable that governs the forest CH4 sink. The positive relationship observed in temperate forest further suggests that the variability of CH4 uptake between the forests with the same dominant species but different soil characteristics can be partially explained by the SOM content. It belongs to group 14 of the periodic table. 31, 119 (2021). Environ. Connect and share knowledge within a single location that is structured and easy to search.
