土壤条件的恢复对于生态系统的成功恢复至关重要，因此，对于实现联合国生态系统恢复十年的目标至关重要。在这里，我们评估土壤如何抵抗森林转换和农业用地，以及土壤如何恢复在随后的热带森林演替废弃的农田。我们首要的问题是土壤抵抗力和恢复如何取决于当地的条件，如气候，土壤类型和土地利用历史。对于300个地块在21个地点在新热带区，我们使用了时序的方法，其中我们采样土壤从两个深度在古老的森林，农田（即农田和牧场），次生林不同的年龄（1-95年），因为放弃。我们测量了六个土壤性质，采用标准化的抽样设计和实验室分析。土壤阻力很大程度上取决于当地条件。高活性粘土（即高肥力）上的农田和场地在砍伐森林和随后的农业使用过程中表现出体积密度的大幅增加和pH值、碳（C）和氮（N）的下降。阻力较低，在这样的网站可能是因为在农田中的细根生物量在上层土壤中急剧下降，并从以前生产的古老森林（高活性粘土）的凋落物输入下降。土壤恢复也在很大程度上取决于当地条件。在森林演替过程中，高活性粘土和农田减少最强烈的容重和增加的C和N，可能是因为强烈压实的土壤，低C和N后，农田废弃，并由于快速植被恢复高活性粘土导致更大的细根生长和凋落物输入。此外，在低降水量的网站在pH值下降，而网站在高降水量的N增加和C：N比下降。可提取的磷（P）没有恢复在演替过程中，这表明随着森林年龄增加的P限制。这些结果表明，有效的土壤恢复不存在单一的解决方案，应根据当地条件确定恢复策略。这篇文章是“了解森林景观恢复：加强联合国生态系统恢复十年的科学基础”主题的一部分。
The recovery of soil conditions is crucial for successful ecosystem restoration and, hence, for achieving the goals of the UN Decade on Ecosystem Restoration. Here, we assess how soils resist forest conversion and agricultural land use, and how soils recover during subsequent tropical forest succession on abandoned agricultural fields. Our overarching question is how soil resistance and recovery depend on local conditions such as climate, soil type and land-use history. For 300 plots in 21 sites across the Neotropics, we used a chronosequence approach in which we sampled soils from two depths in old-growth forests, agricultural fields (i.e. crop fields and pastures), and secondary forests that differ in age (1–95 years) since abandonment. We measured six soil properties using a standardized sampling design and laboratory analyses. Soil resistance strongly depended on local conditions. Croplands and sites on high-activity clay (i.e. high fertility) show strong increases in bulk density and decreases in pH, carbon (C) and nitrogen (N) during deforestation and subsequent agricultural use. Resistance is lower in such sites probably because of a sharp decline in fine root biomass in croplands in the upper soil layers, and a decline in litter input from formerly productive old-growth forest (on high-activity clays). Soil recovery also strongly depended on local conditions. During forest succession, high-activity clays and croplands decreased most strongly in bulk density and increased in C and N, possibly because of strongly compacted soils with low C and N after cropland abandonment, and because of rapid vegetation recovery in high-activity clays leading to greater fine root growth and litter input. Furthermore, sites at low precipitation decreased in pH, whereas sites at high precipitation increased in N and decreased in C : N ratio. Extractable phosphorus (P) did not recover during succession, suggesting increased P limitation as forests age. These results indicate that no single solution exists for effective soil restoration and that local site conditions should determine the restoration strategies. This article is part of the theme issue ‘Understanding forest landscape restoration: reinforcing scientific foundations for the UN Decade on Ecosystem Restoration’.
