Volatile organic compound (VOC) emissions from ecosystems to the atmosphere have been widely studied, and the importance of soil contributions to VOC fluxes has received increasing attention. We suggest that while soil VOC emissions may be important in some situations, soil uptake of VOCs by microbial degradation is likely an omnipresent process, as also recently suggested by Trowbridge et al. (2020, https://doi.org/10.1029/2019JG005479). To be able to model net VOC fluxes, we need to be able to estimate both soil release and uptake processes and their drivers.

土壤对挥发性有机化合物的吸收：普遍存在且被低估了吗？

从生态系统到大气的挥发性有机化合物（VOC）排放已得到广泛研究，并且土壤对VOC通量的贡献的重要性日益受到关注。我们建议，尽管在某些情况下土壤VOC的排放可能很重要，但微生物降解对土壤中VOC的吸收可能是一个无所不在的过程，正如Trowbridge等人最近所指出的那样。（2020，https://doi.org/10.1029/2019JG005479）。为了能够模拟净VOC通量，我们需要能够估计土壤释放和吸收过程及其驱动因素。
