Identifying the drivers of soil organic carbon (SOC) stock changes is of the utmost importance to contribute to global challenges like climate change, land degradation, biodiversity loss, or food security. Evaluating the impacts of land use and management practices in agriculture and forestry on SOC is still challenging. Merging datasets or making databases interoperable is a promising way, but still has several semantic challenges. So far, a comprehensive thesaurus and classification of management practices in agriculture and forestry has been lacking, especially while focusing on SOC storage. Therefore, the aim of this paper is to present a first comprehensive thesaurus for management practices driving SOC storage (DATA4C+). The DATA4C+ thesaurus contains 224 classified and defined terms related to land management practices in agriculture and forestry. It is organized as a hierarchical tree reflecting the drivers of SOC storage. It is oriented to be used by scientists in agronomy, forestry, and soil sciences with the aim of uniformizing the description of practices influencing SOC in their original research. It is accessible in Agroportal (http://agroportal.lirmm.fr/ontologies/DATA4CPLUS, last access: 24 March 2022) to enhance its findability, accessibility, interoperability, and reuse by scientists and others such as laboratories or land managers. Future uses of the DATA4C+ thesaurus will be crucial to improve and enrich it, but also to raise the quality of meta-analyses on SOC, and ultimately help policymakers to identify efficient agricultural and forest management practices to enhance SOC storage.

土壤有机碳储存的语义：DATA4C+，农业和林业管理实践的综合词库和分类

确定土壤有机碳 (SOC) 储量变化的驱动因素对于应对气候变化、土地退化、生物多样性丧失或粮食安全等全球挑战至关重要。评估农业和林业土地利用和管理实践对 SOC 的影响仍然具有挑战性。合并数据集或使数据库可互操作是一种很有前途的方法，但仍然存在一些语义挑战。到目前为止，一直缺乏全面的农业和林业管理实践的词典和分类，特别是在关注 SOC 存储时。因此，本文的目的是为驱动 SOC 存储 (DATA4C + ) 的管理实践提供第一个综合叙词表。DATA4C +词库包含 224 个与农业和林业土地管理实践相关的分类和定义术语。它被组织为反映 SOC 存储驱动程序的分层树。它旨在供农学、林业和土壤科学领域的科学家使用，目的是在他们的原始研究中统一描述影响 SOC 的实践。它可在 Agroportal（http://agroportal.lirmm.fr/ontologies/DATA4CPLUS，最后访问时间：2022 年 3 月 24 日）中访问，以增强其可发现性、可访问性、互操作性和科学家和其他人（如实验室或土地管理者）的重用性。DATA4C +的未来用途叙词表对于改进和丰富它至关重要，而且对于提高 SOC 元分析的质量，并最终帮助决策者确定有效的农业和森林管理实践以增强 SOC 存储。
