Review of Nutrient Management Systems for Florida Vegetable Producers: A White Paper from the UF/IFAS Vegetable Fertilizer Task Force

Abstract

HS1156, a 14-page white paper from the UF/IFAS Vegetable Fertilizer Task Force, identifies differences between actual fertilization practices and UF/IFAS fertilizer recommendations, especially for vegetables grown with subsurface (Central and South Florida) and overhead (Miami-Dade County) irrigation. The recommendations of the VFTF aim at bridging the gaps between science-based results and the diversity in production systems found in the Florida vegetable industry. Includes references.

Nitrogen Use Efficiency and Yield Levels Using Soluble and Controlled-release Urea Formulations in Tomato Production

“…However, FL vegetable growers may apply N fertilizer rates higher than the recommended to potentially limit negative yield impacts from leaching rainfall (Hochmuth and Hanlon 2014). Commercial tomato grower N fertilization often exceeds 470 kgÁha À1 per production season (Cantliffe et al 2009); the variability of applied N among growers within Florida may be due to the differences in duration of seasonal production. For instance, the average tomato production season in north Florida is $13 weeks and there are typically two seasons per year (fall and spring), whereas in south Florida, production can last up to 18 weeks and there may be three production seasons per year (fall, winter, and spring) (Ozores-Hampton et al 2015).…”
