Annually, comparative citrus budgets are tabulated for the Central Florida, Southwest Florida, and Indian River citrus producing areas. The listed estimated comparative costs in Tables 1, 2, and 3 (Table 4 contains footnotes u, v, w, x, and y for Tables 1, 2,and 3) are examples only and may not represent your particular grove situation. The budget cost items for Central Florida and Indian River represent a custom-managed operation, and the budget cost items for Southwest Florida costs represent an owner-managed operation.
The 2001-2002 comparative budgets are presented in three scenarios:
Low Cost Processed Fruit Cultural Program.
Reduced Cost Processed/ Fresh Fruit Cultural Program.
Typical/Historical Fresh Fruit Cultural Program.
Scenarios 1 and 2 represent costs of two possible cultural programs directed toward reducing expenditures for fruit grown primarily for the processed market. The third scenario represents typical costs of grove practices which have been performed for citrus grown for the fresh fruit market. Modified herbicide and/or spray and fertilizer programs account for the reduced costs. Note: Before modifying a grove management program to reduce costs, an evaluation of the market program (processed or fresh), yield, and specific cultural problems (nutrition, disease, etc.) for the specific grove site should be made.
Each budget (Tables 1, 2, and 3) lists the costs of individual grove care practices normally performed in a citrus grove. The costs are categorized into cumulative sub-totals for the unirrigated processed program and the irrigated fresh fruit program. Although the estimated annual per-acre grove costs listed in each budget are representative for a mature citrus grove (10+ years old), the grove care costs for a specific grove site may differ depending upon tree age, tree density, and grove practices. Extensive tree loss due to blight or tristeza could at least double, if not increase more, the tree replacement and care costs. Also, travel and setup costs may vary due to the size of the citrus grove and distance from the grove equipment barn. The mandatory decontamination requirements to help control the spread of Citrus Canker add to the total operational costs as illustrated in Table 5.
Included with the comparative budget sheets are estimated "delivered-in" costs for Central Florida Valencia oranges, Southwest Florida Hamlin oranges, and Indian River grapefruit (Table 5). The "delivered-in" costs for oranges represent the processed fruit market, while the cost for grapefruit represents the fresh market. The estimated "delivered-in" costs include total cultural/production costs, management and regulatory costs, and harvesting costs.
The budgeted cost information presented herein is the most current available. The budget cost items have been revised to reflect current grove practices being used by growers (e.g., chemical mowing, different spray materials and rates of fertilization, microsprinkler irrigation, more reset trees, etc.). Although average per-acre yields have increased due to higher per-acre tree densities, the drought situation in recent years has increased tree stress and may have affected yields. Additional information on budgeting and cost analysis can be obtained by contacting the author or your County Extension Citrus Specialist.

u Although estimated annual per-acre grove costs are representative for mature citrus groves (10+ years), grove-care costs for specific grove sites may differ based on tree age, tree density, and grove practices. The budget cost items have been revised to reflect current grove practices, so revised costs for each grove practice shown may be higher or lower than previously reported. Budget costs for Central Florida, Indian River, and Southwest Florida represent custom-managed operations, which means all equipment costs are based on average custom rate costs and a 10% handling and supervision charge is added to material cost. A management charge for equipment supervision is not included. The extended drought situation during the last two seasons has increased tree stress, especially trees weakened from blight and tristeza. This has resulted in greater tree loss as reflected in higher reset replacement costs. Also, average per-acre yields have been affected by drought conditions. |

y Where "equipment use" or "application" is listed (discing, hedging, spray application), "average custom charge" (cost) represents charges for equipment repairs, maintenance, labor, and overhead. Exceptions are mowing, spraying, and herbicide application costs for Southwest Florida which "represent costs for non-custom managed (owner-managed) operations." Management charges/costs are based on monthly charges or percentage of gross management sales. There can be harvesting supervision costs for overseeing/coordinating harvesting. Cost items not included in the budget are ad valorem taxes and interest on grove investments. Overhead and adminstrative costs may be 12% of total grove-care costs; costs vary from grove to grove, depending on age, location, and time of purchase or establishment. Except for Southwest Florida, a 10% supervision/handling charge of cost/price of materials is included in "materials expense." |
