Abstract A recent meta-analysis (Zhang et al., 2020) stated that acidification induced by nitrogen (N) (over)fertilization increases soil organic carbon (SOC) accumulation. This Letter disagrees with that statement regarding acidification effects on SOC accumulation. We especially wish to show how processing of large datasets might mislead conclusions, and may have fatal consequences for land management. Another crucial point we wish to raise is that the role of carbonates for carbon stocks and induced CO2 losses to the atmosphere has been completely disregarded in the soil acidification discussion.

致编辑的信：酸化真的会增加农田的土壤碳吗？大型数据集的统计分析如何误导结论

摘要 最近的一项荟萃​​分析（Zhang 等人，2020 年）指出，氮（N）（过量）施肥引起的酸化会增加土壤有机碳 (SOC) 的积累。这封信不同意关于酸化对 SOC 积累的影响的说法。我们特别希望展示大型数据集的处理如何可能误导结论，并可能对土地管理产生致命的后果。我们希望提出的另一个关键点是，在土壤酸化的讨论中完全忽略了碳酸盐对碳储量和诱导的二氧化碳损失到大气中的作用。
