Abstract

Snapbean production in the Suwannee Valley occurs on sandy soils that are highly vulnerable to nitrogen leaching, making efficient fertilizer management essential for both crop performance and environmental protection. Controlled-release fertilizers (CRFs) offer a potential strategy to improve nitrogen delivery by synchronizing nutrient releases with crop demand while reducing losses to groundwater.
