Abstract
Abnormally high rainfall may increase both the uncertainty about nitrogen fertilizer use in agriculture and the discharge of nitrate into water streams. Furthermore, changes in climate may lead to higher variability in rainfall with more frequent abnormal precipitation. In this study, we use experimental data from the Iowa Soybean Association (ISA) to investigate the effects of abnormal rainfall on farm nitrogen management, considering both farmer profitability and the potential for environmental damages.
