Net Irrigation Requirements for Florida Turfgrass Lawns: Part 2 — Reference Evapotranspiration Calculation

This Net Irrigation Requirements for Florida Turfgrass Lawns series explains the process of estimating net irrigation requirements for Florida turfgrasses. The process used here gives a long-term (30-year) historical analysis of turfgrass monthly net irrigation requirements. This article shows the calculation of evapotranspiration for selected sites throughout the state (plus one in Alabama, to cover the west side of the Florida Panhandle). Written by Consuelo C. Romero, Bernard Cardenas, and Michael D. Dukes, and published by the UF/IFAS Department of Agricultural and Biological Engineering, revised August 2024.
