Crop production, equivalent or exceeding any that has been attained or predicted, is possible from the sandy soils of peninsular Florida. However, extreme variability occurs from season to season, from field to field, and even within fields. Well managed field corn in Florida has averaged 50–70 bu/A, while maximum yields with irrigation have rarely exceeded 125 bu/A. Production of fresh market tomatoes, which in Florida have an annual value of 100 million dollars, varies from failure to 25 tons/A using the common cultural procedures. By utilizing a precision production system, consistent yields of 45 to 50 tons/A of fresh market tomatoes as well as 160–180 bu/A of field corn have been obtained. Combinations of controllable and non‐controllable factors with nutrition as a key component have been evaluated and selected as an approach to attain optimal production.
