4R Farming

Florida Tomatoes

This is a tomato farm in Florida. The farm plants tomatoes twice a year and harvests 4 to 6 times per year, 2 to 3 times per planting. The farm has increased soil sampling frequency and switched sources, adding poultry little pellets to the fertilizer that is incorporated in the bed for the plants. Starting in 2017 fertilizer was mixed with the bed prior to covering with plastic versus applied to the surface of the bed prior to covering with plastic and planting. A sidedress fertilizer is applied following each picking.


Changing from basic to more advanced 4R practices the farmer decreased cost per acre by $896.27 and cut nitrogen application rates by 60 percent by changing placement, source, and timing of nitrogen applications.
