High-Density Citrus Plantings Could be Path to Increased Profits

Florida citrus growers have seen harvests decrease and production costs increase ever since citrus greening was discovered in south Florida in 2005. Profits have decreased due to the damage caused by the disease, but researchers with UF/IFAS advise that high-density plantings could possibly allow citrus growers to increase profits, until a more viable treatment or cure is found.

Details of High-Density Plantings:

According to UF/IFAS researchers, the statewide average planting density in the Florida citrus industry is 145 citrus trees per acre. The research coming out of UF/IFAS citrus test plots shows that trees with 220 and 303 trees per acre yield more fruit than those at the 145 trees per acre density. This higher density results in a higher harvest, which UF/IFAS researchers maintain could offset losses caused by citrus greening, also called HLB. High-density plantings can also reduce the production costs of a citrus operation, such as pest spraying, irrigation, and fertilizers, when compared with conventionally-spaced groves. At the end of the day, each box of citrus costs less in inputs to produce, which can also increase profits.

Since every citrus operation is different, UF/IFAS citrus economist Ariel Singerman put together an Excel spreadsheet so that citrus growers can have a user-friendly resource to evaluate the cost to establish and keep up a new citrus grove. It provides profitability and return-on-investment estimates utilizing average data concerning variables like irrigation, production practices and costs, machinery used, yield per tree, and market prices. Growers can customize the spreadsheet, changing the variables to align with the details of their own operation for more precise estimates. That way, growers can explore what planting density would be the most beneficial. The spreadsheet is free, though access must be granted via email, and can be found at https://crec.ifas.ufl.edu/extension/economics/economic_tools.shtml.
