This analysis evaluates the costs per acre for various agricultural practices focused on nitrogen (N) and phosphorus (P) application. Each practice is fully evaluated to estimate the costs associated with N and P while aiming for reductions of 20% or 45%. The findings are combined to provide comprehensive insights on nitrogen and phosphorus management in both in-field and edge-of-field scenarios, including land use changes and point sources. Results and scenarios are illustrated through a statewide survey, aiding agricultural stakeholders in decision-making.
