摘要：

Among the various policy options available to reduce the excess application of nitrogen, including restricting the nitrogen fertilizer application rale and taxing nitrogen fertilizer, adoption of a soybean-corn rotation, while coincidentally limiting the nitrogen fertilizer application rate, will have the lowest compliance cost for a farmer. This rotation also will be the most efficient option, by maintaining a profitable level of crop production irrespective of the ratio of the nitrogen fertilizer price and the corn price. Using rotation on cropland with a high potential for leaching will have a smaller compliance cost relative to that found when -the cropland has moderate leaching potential.
