A bill for an act providing for a pilot program to reduce the use of commercial nitrogen-based fertilizers to produce crops, and making appropriations.

SF 429 creates a pilot program to help Iowa farmers reduce commercial nitrogen fertilizer use by offering $5+ per acre incentives for adopting approved alternatives like soil conditioners or biofertilizers. The program, funded with $2 million annually starting in 2025, targets field crop producers statewide and aims to cut fertilizer application rates by 15% or 30 pounds per acre. Participants must document their use of qualifying products and follow division-approved methods. The program runs until 2030, requiring annual reports on progress and outcomes.
