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.

The publication focuses on nitrogen (N) requirements for corn production using best management practices (BMPs) in Florida. The intended audience is corn producers, agricultural consultants, Extension agents, Extension specialists, and researchers. The aim is to provide and recommend BMPs that comply with statewide BMP guidelines, maximizing the yield and economic return while minimizing environmental N losses. The guidelines present results from multi-year, multi-site, field-based research conducted by the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS). The small plot research was conducted at the UF/IFAS North Florida Research and Education Center, Suwannee Valley, Live Oak, Florida (NFREC-SV). The publication includes a recommendation in terms of N required per bushel of productivity.
