Mainstream agriculture is dependent on N fertilizer, and use patterns are polluting water resources. A 5-cent tax on N fertilizer is shown to have three benefits. National N fertilizer use is estimated to decline about 10%. Use of legume-produced N increases, and crop use of N declines only 5%. A reduction in wasted legume-produced N equal to 2.5% of N application in the baseline occurs because of increased use of legumes and other crops in rotation. The N tax is not without costs. Soil erosion and pesticide use are estimated to increase 2.2 and 1.7%, respectively, in response to the tax. %U https://www.jswconline.org/content/jswc/45/1/140.full.pdf
