0216316DrinkwaterThis is an exploratory project that will use meta analysis linked to modeling to provide a synthesis of the extensive literature published on carbon and nitrogen cycling processes in agricultural systems. The expectation is to be able to predict the impact of changes in management practices on primary productivity, yields and global biogeochemical cycles. Another product of this work will be to determine the impact of substituting N-fixation for mineral N fertilization.

这是一个探索性项目，将使用与建模相关的元分析来综合发表在农业系统中碳和氮循环过程的大量文献。期望能够预测管理做法的变化对初级生产力、产量和全球生物地球化学循环的影响。这项工作的另一个成果将是确定用固氮代替矿物氮肥的影响。
