A Dynamic Economic Analysis of Nitrate Leaching in Corn Production under Nonuniform Irrigation Conditions
构建了一个包含氮肥和灌溉水控制变量的动态经济模型，分析灌溉系统非均匀性对玉米生产及硝酸盐淋溶的影响，并评估不同政策选项（如技术投资、淋溶限制等）的经济效果。
Abstract We develop a dynamic economic model that includes control variables for both nitrogen fertilizer and irrigation water to analyze interseasonal corn production and nitrate leaching in the presence of irrigation system nonuniformity. The economic model is used to estimate profit‐maximizing nutrient management plans under varying levels of system uniformity. The model is also used to appraise several policy options that have been proposed in the nitrate leaching literature as a means of regulating water quality. Investments in technology are considered, as well as limits on nitrate leaching, nitrogen fertilizer, and irrigation water.
