Several countries have implemented standards, regulations, or subsidies to improve nitrogen and phosphorus use efficiency as part of broader policy efforts to incentivize sustainable agriculture and benefit the environment. Nitrogen and phosphorus are essential nutrients for crop growth and development, but their inefficient use can lead to environmental pollution, greenhouse gas emissions, and economic losses.  While there are no global data sources yet tracking policies around nitrogen and phosphorus use efficiency, several countries have implemented standards, regulations, or subsidies for this purpose. For example, in the United States, the U.S. Department of Agriculture provides cost-share programs to farmers to implement conservation practices that reduce nutrient losses. In Argentina, the government has implemented a fertilizer management plan that includes soil testing, crop rotation, and the use of slow-release fertilizers. In Canada, the government has established a nutrient management framework that includes guidelines for fertilizer application rates and timing.
