Nitrogen loss from corn farming in the Midwest is a major cause of water pollution and greenhouse gas emission. Focusing on farms in Iowa, Illinois, and Michigan, this project will address important gaps in our current understanding of the links between the decisions of corn farmers and the quality of water and air in the region. Researchers will refine previous work on nitrogen loss to take variability within farm fields into account, identify the factors that influence the decisions of farmers about fertilizer use, and develop an integrated, quantitative model that couples the natural dynamics of nitrogen cycling with the social and economic dynamics of farming. Results from this project will help farmers and policy makers evaluate alternative ways to reduce water pollution and greenhouse gas emissions from Midwestern row crops. A Nitrogen Roundtable will bring researchers, managers, and stakeholders together, and the project will engage K-12 educators to disseminate research results to the public. The model to be produced is expected to provide a new decision-support tool for more sustainable agriculture in the U.S.

中西部玉米养殖量流失是水污染和温室气体排放的主要原因。该项目专注于爱荷华州，伊利诺伊州和密歇根州的农场，将解决我们当前对玉米农民决策与该地区水和空气质量之间联系的重要差距。 研究人员将完善先前关于氮损失的工作，以考虑到农场领域内的可变性，确定影响农民对肥料使用的决策的因素，并开发出一种综合的定量模型，使氮循环的自然动态与社会和经济的自然动态结合在一起农业的动态。该项目的结果将帮助农民和政策制定者评估替代方法，以减少中西部行作物的水污染和温室气体排放。氮圆桌会议将使研究人员，经理和利益相关者聚集在一起，该项目将吸引K-12教育者向公众传播研究结果。预计要生产的模型将为美国提供更可持续的农业提供新的决策支持工具
