Soil carbon is vitally important to the fertility of soils and to the long-term sustainability of ecosystems and the important services that they provide. Increasing temperatures and deposition of nitrogen to forests is shifting the biogeochemical cycling of soil carbon and fundamentally changing ecosystem function. The proposed research program will use highly advanced analytical tools to elucidate how long-term soil warming and increased nitrogen are impacting forests over time. This highly defined, molecular-level information will explain how these processes are transformed. This knowledge will be used to develop informed policies to protect these precious ecosystems.

土壤碳对土壤肥力、生态系统的长期可持续性及其提供的重要服务至关重要。气温升高和氮向森林的沉积正在改变土壤碳的生物地球化学循环，并从根本上改变生态系统功能。拟议的研究计划将使用高度先进的分析工具来阐明长期土壤变暖和氮含量增加是如何随着时间的推移影响森林的。这种高度定义的分子水平信息将解释这些过程是如何转化的。这些知识将用于制定明智的政策来保护这些宝贵的生态系统。
