Over the last few years, in the literature on the incorporation of crop residues in agricultural fields to mitigate climate change, there has been a growing tendency to no longer distinguish between the storage and the sequestration of organic carbon in soils. Applying, apparently for the first time, a simple “back-of-the-envelope” calculation to available mineralization kinetics data, we show graphically that there are fundamental differences, both quantitatively and qualitatively, between the two concepts of storage and sequestration. To avoid confusion, they should therefore never be used interchangeably, especially when addressing farmers and policymakers. Several simplifying assumptions made in the calculations, and about which a considerable lack of understanding persists, mean that at this stage, the graphical visualization we obtained is likely to still be optimistic in terms of the already low (10%) efficacy of sequestering carbon in soils. Several research avenues are outlined to deepen our grasp of the processes involved.

土壤碳储存不是封存：它们基本差异的直观图形可视化

在过去的几年中，在关于将农作物残留物纳入农田以减缓气候变化的文献中，越来越倾向于不再区分土壤中有机碳的储存和封存。显然是第一次将简单的“粗略计算”应用于可用的矿化动力学数据，我们以图形方式表明，储存和封存这两个概念之间在数量和质量上存在根本差异。因此，为避免混淆，它们绝不能互换使用，尤其是在针对农民和政策制定者时。计算中做出的几个简化假设，以及仍然存在相当大的理解不足，意味着在这个阶段，我们获得的图形可视化可能仍然乐观，因为在土壤中封存碳的效率已经很低 (10%)。概述了几种研究途径，以加深我们对所涉及过程的理解。
