The 2004-05 Florida orange forecast, released today by the USDA Agricultural
Statistics Board, is a hurricane reduced 176.0 million boxes. This forecast is for conditions
as of October 1, and takes into account losses of fruit from the four hurricanes that passed
through citrus producing areas of the State in August and September. The forecast is 66
million boxes, or 27 percent, less than last season's near record 242.0 million boxes. The
total is divided into the early-midseason-Navel forecast of 92.0 million boxes and the
Valencia portion of 84.0 million.

All forecasts are based on tree inventory, fruit counts, and fruit measurements made
by the Florida Agricultural Statistics Service. Analysis of these factors projects the
quantity of fruit to be utilized during the season. Page 6 of this release details these
procedures.
POST-HURRICANE ADAPTATIONS
This season the annual Limb Count survey was modified to
account for the effects of recent hurricanes -- Charley on August 13th
and Frances on September 5th. In order to better assess the damage,
crews refrained from surveying the areas affected for a period of time
and concentrated on other counties. When work resumed in the affected areas,
samples that were not counted prior to the storms were
completed. To help adjust for the storm damages,
approximately one-third of the limbs in previously sampled
groves were recounted. This work was completed by September
25th, one day before Hurricane Jeanne. To account for
additional fruit loss from Jeanne, field personnel assessed
dropped fruit while collecting samples on the monthly Maturity
Survey. Additional loss factors by location, type, and age of tree
were then applied to fruit numbers from the Limb Count surveys.
In addition, the monthly size and drop survey was
modified to account for storm losses in the areas affected. This
survey will monitor fruit droppage and size in the coming months.
Bearing tree numbers used in the forecasts include trees
planted in 2001 and earlier. Attrition rates of the last several
seasons were considered when determining the rate to be
applied to the 2004 Commercial Citrus Inventory that was
completed before the hurricanes. Additional losses were
estimated to account for trees lost from the hurricanes.
In seasons not affected by unusual weather events, the
objective count procedures are designed to be, and have been
successful at projecting final utilization within five percent in
most seasons. In the past ten seasons, final utilization differed
from the October forecast by an average of 3.9 percent.
Accuracy of this season's forecasts will be affected by survey
modifications and future weather conditions that may alter fruit
size and drop assumptions.
FCOJ YIELD 1.56 GALLONS PER BOX
The all orange FCOJ yield projection is 1.56 gallons per
box of 42 degrees Brix concentrate. Last season's final yield as
reported by the Florida Citrus Processors Association was
1.5565 gallons per box. Final yield over the past five seasons
has been very consistent, varying from a low of 1.54 to a high
of 1.58. The record high yield of 1.63 gallons occurred in the
1998-99 season. A separate projection for fruit going into the
early-midseason and late categories will be made in the January
release. Projections of yield assume the processing relationships of
recent seasons. See pages 3 and 4 for further details.
Excluding Navels, 32.0 million bearing trees were used in the
expansions, down 1.3 percent from last season. Bearing tree numbers have
been declining since the 1998-99 season.
The average fruit per tree from the Limb Count survey (weighted by
the 25 cell age/area matrix) is 30 percent less than last season and the lowest
since the 1982-83 season. The Central area had the highest fruit per tree
average, followed closely by the Southern area. Pieces of fruit per tree in the
Indian River District, affected most severely by the recent hurricanes, have
approximately one-third of the state average. The early portion, mostly Hamlins,
represents 86 percent of the early-mid fruit population.
Fruit size in September ties as the second lowest in a ten season series,
however the growth rate is projected to be slightly above average due to the
abundant rainfall, and light fruit set. Average size is projected to be the third
lowest in ten years at harvest. At this size, it will take 21 more fruit than last
season to make a 90 pound equivalent box.
Current drop is slightly below average; however, drop is expected to
be above average by harvest. Future weather conditions could alter the
projection for both drop and size.

| Navel | 1,862 | 249 | 14 | 134 |
| Valencia | 41,208 | 529 | 15 | 207 |
The Navel forecast at 3.0 million boxes is 30 percent less than last
season's 4.3 million boxes harvested. This forecast includes an allocation of
1.0 million boxes for non-certified and gift fruit. The current forecast is the
lowest since the 2.6 million boxes utilized in the 1987-88 season.
The number of bearing trees has been declining since the 1996-97
season and now are estimated at 1.9 million, eight percent less than last
season. Average fruit per tree is 34 percent less than last season and the
lowest on record since forecasting Navels separately beginning in the 1986-
87 season. Fruit sizes are smaller than average and with the current growth
rates fruit is expected to remain slightly below average.
Fruit drop is very low at this time, but is expected to be slightly above
average by the end of the season. A good portion of this crop this year will
be used by fund raising groups.
VALENCIA ORANGES 84.0 MILLION BOXES
The Valencia forecast of 84.0 million boxes is the lowest since the
74.0 million boxes harvested in the 1998-99 season. This forecast is 28
percent less than the record 116.0 million boxes harvested last season.
Estimated bearing tree numbers at 41.2 million are up compared to
40.9 million last season. A high proportion of the trees planted in the last few
years have been Valencias, which are now coming into production.
Average fruit per tree decreased 22 percent from last season's level and
is the second lowest average in a 10 year series, with the 2002-03 season
being slightly lower. The fruit population distribution shows 70 percent of
the crop in the Central and Southern areas, due to the heavy hurricane
damage in the Western and Indian River areas. The Southern area,
predominantly the Gulf Marketing District, has 38 percent as compared to 32
percent last season.
Despite low average fruit per tree, the current below average growth
rate has resulted in projected fruit sizes to be slightly below the ten year
average. Early season above average rainfall may continue to affect growth
rates and fruit sizes. Current drop rates are slightly below average, but are
expected to be above average at harvest. Due to the longer time to maturity
of Valencias than other orange varieties and weather conditions during
the next several months, these fruit size and droppage assumptions
could change and alter the expected crop size.
TEMPLES 800,000 BOXES
The Temple forecast of 800,000 boxes is the lowest amount since
the series began in 1954-55. If realized, this crop will be 43 percent less
than last season's utilization of 1.4 million boxes, and 87 percent below
the record 6.0 million boxes.
Bearing tree numbers continue to decline, down 12 percent from
last season. Also, because of the hurricanes, average fruit per tree is
down 43 percent from last season.
As with other varieties, trees were uprooted and split from the
hurricanes that affected the east coast and interior growing areas.
Droppage is expected to be above average although weather effects of
the next several months may alter this projection. Average fruit sizes
are expected to be larger than average, but also may be altered by future
weather conditions.
TANGELOS 1.4 MILLION BOXES
The tangelo forecast of 1.4 million boxes is 40 percent more
than last season's greatly reduced 1.0 million boxes. Although not a record
low, last season's production is the lowest in a downward trend dating back
to 1979-80. Last season, the average fruit per tree was very low. This season,
in spite of the hurricanes, average fruit per tree is 81 percent more than last.
Bearing tree numbers are down 21 percent from last season. Fruit
sizes are smaller then average at this time and are expected to be smaller
at harvest. Droppage at harvest is expected to be above average, but
may be altered because of weather conditions in the next several
months.

Results of the second maturity tests of the 2004-05 season
for all but the late oranges, which were tested for the first time,
are to the left. Samples tested are from groves on routes which
cover all five major citrus producing areas.
Sample size for all types have remained constant for the
past several seasons. The grapefruit sample size was 100 at the
start of this season, which included 50 samples each for the white
and colored seedless types. After the hurricanes, only 45 white
samples had sufficient fruit remaining to test, however 48 colored
grapefruit samples remained for use. All of the 120 early oranges,
53 of the 55 midseason, and 144 of the 150 Valencias were
available for testing.
Samples were collected September 28-29 and tested at the
Orlando test laboratory of the Florida Agricultural Statistics
Service. Only regular bloom fruit is collected and tested.
Rainfall through the summer has been excessive in all
areas. Lower interior and coastal areas have received more than
the upper interior with some recording stations showing two or
three times the average for the year.
In comparison to previous seasons, acid levels are the
highest since 2000-01 for the early and late varieties and 1999-00
for the midseason fruit. Brix levels are lower than in recent
seasons. Grapefruit acid levels are higher than last season at this
time.
The ratio of solids to acid is low reflecting the high acid
levels. Juice levels for early oranges are slightly lower than last
season but higher for midseasons and Valencias. Generally,
maturity levels are two or three weeks behind last season.
Some fresh fruit packers opened in late September.
Varieties being shipped include early oranges, early tangerines,
and grapefruit.

The forecast of grapefruit for certified utilization is 15.0 million boxes. This forecast
is greatly reduced from previous seasons because of the effects of four hurricanes that hit
the State's growing areas in August and September. Only the Southern area was not
directly affected with Hendry, Collier, and Lee counties receiving primarily heavy rainfall
amounts on several occasions. If realized, this forecast will be 63 percent less than last
season's production.

Colored grapefruit bearing tree numbers are estimated at
5.366 million, six percent less than last season. Although attrition
rates of older trees continue to be high, the number of trees planted
in 2001 was higher than in the previous seven years. Average fruit
per tree is greatly reduced because of the hurricanes and, at 210
pieces per tree, is 58 percent less than last season. Colored
grapefruit was less affected by the storms because of the many
younger trees in this category. Average fruit sizes at harvest are
estimated larger than last season, but weather conditions later in
the season may affect the outcome of this projection. Droppage is
estimated above average at 12 percent.
ALL TANGERINES 4.7 MILLION BOXES
The forecast of all tangerines at 4.7 million boxes is 28
percent less than produced last season (due to the hurricanes) and
is the lowest production since the 1995-96 season. The forecast is
comprised of the early varieties (Fallglo and Sunburst) at 2.5
million boxes and the Honey variety at 2.2 million.
Fallglo tangerines, the earliest maturing variety, comprises
about 25 percent of the early category forecast. Bearing trees at
317,000 are down 10 percent from last season. Some trees were
reported badly broken by the hurricanes. Average fruit per tree is
reduced because of the storms, but fruit sizes are above average.
Droppage is projected near the average of 14 percent. Limited
harvest has started.
Sunburst tangerines comprise the majority of the early
tangerine production. Bearing tree numbers are estimated at 1.277
million, down seven percent from last season. Trees were reported
broken because of the storms. Fruit per tree at 503, a relatively
high amount, was reduced by the storms. Fruit sizes are projected
to be larger than average at harvest. Droppage is projected near
average.
The Honey tangerine forecast of 2.2 million boxes is the
smallest crop since the 2.05 million boxes produced in the 2000-01
season. A large portion of these trees are located in the Southern
area and were not affected by the storms. Fruit sizes are projected
to be slightly larger than average with droppage rates near normal
as well.
FORECAST PROCEDURES FOR THE 2004-05 SEASON
All citrus forecasts except seedy grapefruit are based on actual fruit
counts and measurements. These objective count methods utilize: (1) the
bearing age tree population provided from the latest aerial photography
with field verifications, (2) the average fruit per tree obtained from the
fruit count survey using randomly selected trees and limbs, and (3) the
fruit measurement and fruit drop count surveys to determine fruit sizes and
loss from fruit droppage.
The latest Commercial Citrus Inventory is the base used to determine
forecast tree numbers for this season. All trees planted in 2001 and earlier
are included. An attrition factor by age and area was applied to these base
numbers to account for tree losses since the inventory period. In addition
an adjustment factor was applied to areas affected by the hurricanes to
account for trees blown over, uprooted, and severely damaged.
The same unbiased fruit count procedures were used as in all of the
past 47 seasons. Following the passage of Hurricane Charley on August
13th and Hurricane Frances on September 5th, recounts were conducted on
a sub-sample of trees in the affected areas. Following the passage of
Hurricane Jeanne on September 26th, subjective evaluations were
conducted in each county affected to account for additional green fruit on
the ground. An adjustment factor was then applied by fruit type, county,
and age group of trees to reduce the average fruit per tree estimate.
Fruit size surveys were conducted in August and September. The fruit
loss surveys (drop count) were begun in August and modified following
the first two hurricanes. These surveys, along with historical records, were
used to project the fruit size at harvest and the fruit population that is
expected to remain on trees until harvest.
The chart below describes the relationship of the September 2004
early and midseason orange (excluding Navels) fruit size measurements
with those taken in September 2003. The diameter measurements shown
are the minimum values of each eighth inch range, except for the smallest
values.
