Much research focuses on increasing carbon storage in mineral-associated organic matter (MAOM), in which carbon may persist for centuries to millennia. However, MAOM-targeted management is insufficient because the formation pathways of persistent soil organic matter are diverse and vary with environmental conditions. Effective management must also consider particulate organic matter (POM). In many soils, there is potential for enlarging POM pools, POM can persist over long time scales, and POM can be a direct precursor of MAOM. We present a framework for context-dependent management strategies that recognizes soils as complex systems in which environmental conditions constrain POM and MAOM formation.
许多研究都集中在增加与矿物相关的有机物质（MAOM）中的碳储存，其中碳可能会持续存在数百年到数千年。然而，针对 MAOM 的管理是不够的，因为持久的土壤有机物质的形成途径是多种多样的，并且随环境条件而变化。有效的管理还必须考虑颗粒有机物质（POM）。在许多土壤中，有扩大 POM 库的潜力，POM 可以长时间持续存在，并且 POM 可以是 MAOM 的直接前体。我们提出了一个依赖于上下文的管理策略框架，该框架将土壤视为一个复杂的系统，其中环境条件限制了 POM 和 MAOM 的形成。
