9408712 Coleman Since 1978, long-term research has been conducted on the effects of tillage regimes and the impacts of biotic manipulations on soil organic matter (SOM) dynamics and nutrient cycling processes in southeastern agroecosystems. Several studies have provided information on the long-term changes which are occurring over time-spans of decades. This project will maintain these long-term experiments. A comparative approach will continue to be used in three core areas: soil structure, food webs, and education. This work will continue to be of importance not only in the context of basic ecological relationships, but also as a guide for improvement of agricultural practices. As a project it is an excellent example of the immediate linkage between fundamental discovery and application.

9408712科尔曼（Coleman）自1978年以来，就耕作方案的影响以及生物操纵对土壤有机物（SOM）动力学（SOM）动力学和养分循环过程的影响进行了长期研究。 几项研究提供了有关长期变化的信息，这些变化是在数十年的时间范围内发生的。 该项目将维持这些长期实验。 比较方法将继续在三个核心领域：土壤结构，食物网和教育。 这项工作将不仅在基本生态关系的背景下继续至关重要，而且还将作为改善农业实践的指南。 作为一个项目，这是基本发现与应用之间立即联系的一个很好的例子。
