Advanced production systems for citrus
Field work on citrus to establish new advanced production systems with higher tree densities and improved nutrient management is being conducted in South Florida.
The open hydroponic system uses fertigation intensively and has been shown to improve early growth and production of citrus. This has become more important because citrus greening has reduced production in some groves and increased production costs in nearly all groves.
The increased growth and productivity of young trees will increase the grower’s profits. Greening is known to reduce the leaf content of several key nutrients. Greening symptoms can be reduced and tree growth improved with foliar sprays of these nutrients.
Research work in South Florida is being conducted to determine the amounts and proper timing of these nutrient applications.
