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.

许多研究侧重于增加矿物相关有机质 (MAOM) 中的碳储存，其中碳可能会持续存在数百年至数千年。然而，MAOM 的针对性管理是不够的，因为持久性土壤有机质的形成途径多种多样，并随环境条件而变化。有效的管理还必须考虑颗粒有机物 (POM)。在许多土壤中，存在扩大 POM 池的潜力，POM 可以持续很长时间，并且 POM 可以是 MAOM 的直接前体。我们提出了一个环境相关的管理策略框架，该策略将土壤视为复杂系统，其中环境条件限制了 POM 和 MAOM 的形成。
