Current and emerging policies reflect the close relationship between on-farm nitrogen (N) management practices and reactive N (Nr) in the environment. Farmers today have several potential options to try to reduce Nr from their operations, including widely recognized best management practices such as the 4R Nutrient Stewardship framework. As mitigation protocols develop, farmers must way the cost-benefits of voluntary incentives against the potential economic risk of altering current farm practices.  New tools, such as the US Cropland Greenhouse Gas Calculator, are available for farm decision makers to use to assess the impact a management change will have on Nr. Limitations, benefits, and pitfalls of adopting new on-farm N management practices to reduce on-site Nr will be discussed.
