Farmers in the United States (US) Corn Belt produce ~30% of the world’s corn and soybean, which depends on the use of fertilizers containing both nitrogen (N) and phosphorus (P). However, due to a lack of consistent and reliable information, these farmers tend to over-apply fertilizer. This practice directly affects farmers, as they are paying higher fertilizer costs than necessary, and negatively impacts environmental sustainability. Yet, farmers’ perceptions of nutrient management challenges vary widely as does their willingness to adopt novel nutrient management approaches.
