The Kellogg Biological Station (KBS) LTER project was initiated in 1987 and since then has provided experimental and observational research designed to understand the basic internal ecological relationships that control productivity of field crop ecosystems in North America, independent of external inputs such as pesticides and fertilizers. The project has combined comparative and experimental studies of various cropping systems and unmanaged successional communities to provide ecological knowledge that can direct efficient agronomic management. This project will continue that long-term line of research and will expand it to address understanding and valuation of ecosystem services. This LTER renewal project develops an enlarged conceptual framework that integrates regional watershed and social context into the causes-consequences of changing agricultural ecology and economy. This project contributes to understanding of the structure, function, and dynamics of agricultural ecosystems, advancing understanding of the ecological interactions that underpin productive, sustainable, low-impact agriculture. It assembles and integrates valuable long-term data sets on climate, hydrology, biology, ecology, biogeochemical processes, and other elements of the local and regional ecosystems. The project has broad societal value through its contributions to improved management of agricultural ecosystems. Its broader values also include extensive research-based training, educational program development and K-12 teacher training, and strong and diverse outreach to the public and to policy-makers.

凯洛格生物站(KBS)LTER项目于1987年启动，自那时以来一直提供实验和观测研究，旨在了解控制北美大田作物生态系统生产力的基本内部生态关系，而不依赖于农药和化肥等外部投入。该项目结合了对各种种植制度和无人管理的演替群落的比较和实验研究，以提供能够指导有效农艺管理的生态知识。该项目将继续这一长期研究方向，并将对其进行扩展，以解决对生态系统服务的理解和评估问题。LTER更新项目开发了一个扩大的概念框架，将区域分水岭和社会背景纳入农业生态和经济变化的因果关系中。该项目有助于了解农业生态系统的结构、功能和动态，促进对支撑高产、可持续、低影响农业的生态相互作用的理解。它汇集和整合了关于气候、水文、生物学、生态学、生物地球化学过程以及当地和区域生态系统其他要素的有价值的长期数据集。该项目对改善农业生态系统的管理作出了贡献，具有广泛的社会价值。其更广泛的价值还包括广泛的基于研究的培训、教育项目开发和K-12教师培训，以及面向公众和政策制定者的强有力和多样化的拓展。
