Gulf
Hurricanes Batter South Alabama Cotton Fields
Auburn,
Oct. 10, 2002--- Cotton fields
near the Gulf Coast have been severely battered by Hurricane Isidore
and subsequent weather fronts. Dr. Dale Monks, an agronomist with
the Alabama Cooperative Extension System, and Dr. Bob Goodman, an
Extension agricultural economist, agree that much of the cotton in
the area has suffered extensive damage.
Jim Todd, Mobile County Extension coordinator,
brought the two into survey area fields to help determine if cotton
farmers had significant agronomic and economic damages from wind and
rain damage caused by Hurricane Isidore.
"I visited a number of cotton fields in Mobile
County within days of Isidore's passing through," says Todd.
"I believed it would be helpful for our farmers to get an
objective assessment of damage from some Extension
specialists."
"In Mobile County, we were looking for a good
harvest. Because of Isidore, farmers have had anywhere from 60 to
250 pounds of cotton per acre blown to the ground," says Todd.
In addition to inspecting fields in Mobile County,
Goodman and Monks also visited farms in Baldwin, Escambia and Monroe
counties.
To anyone passing fields beside a highway, the
cotton appears ragged, windblown and uneven. The full extent of
damage may easily be missed in casual observation. A closer
examination reveals that a major economic disaster has occurred in
these four counties.
"It appears that extensive damage has already
occurred, and the stage is set for even more damage to result from
Isidore indirectly, as subsequent weather events unfold to aggravate
the existing situation," says Monks.
Goodman says that the damage was generally, but not
universally more severe nearer the coast.
"However, one of the most severely damaged
fields was in Monroe County, at the northern limit of the damage
area," says Goodman. "We observed that the earlier fields
suffered the most immediate damage. Damage levels to later fields
with more unopened bolls could, due to additional severe weather,
ultimately exceed that level of economic impact. Damage was
generally more severe in fields with higher pre-storm yield
potential."
Winds were not strong enough to completely strip the
open cotton from the fields or to dismantle cotton modules. Cotton
modules are compacted, large bales of picked cotton ready to be
transported to cotton gins.
Goodman says closer examination revealed moderate to
severe damage in almost every field the Extension professionals
visited.
Damage to early cotton (characterized by mostly open
bolls) was typically a combination of wind and boll rot. In some
fields, cotton had been knocked out of the boll and was on the
ground with seeds sprouting.
"Some sprouting of cottonseed was evident in
cotton still on the plant," says Monks. "Extensive boll
rot was already evident in many fields, especially fields that
originally had high yield potential."
It is likely that cotton lint still marginally
attached to the plant will fall before it can be harvested.
Additional boll rot can be expected, and harvesting losses will be
excessive.
"Farmers are going to have quality losses from
boll rot and cottonseed sprouting. Additional quality losses could
occur due to plant regrowth," says Goodman. "Those kinds
of quality losses are going to cost farmers money because their
cotton won't command the same prices as high quality cotton. Also,
the value of cottonseed will be significantly lower, and cottonseed
will be lighter because of sprouting while still in the boll."
Later cotton, characterized by few open bolls at the
time of the storm, was heavily defoliated and twisted by Isidore's
winds. Monks says the resulting root damage and leaf area loss will
limit further development of many of these bolls.
"While most of these bolls may eventually open,
both quality and quantity of lint produced will be affected,"
says Goodman.
Fields with later cotton face the possibility of
further damage from additional tropical storm fronts that move out
of the Gulf of Mexico.
Goodman says another complicating factor in
assessing the damage is the impact Isidore will have on harvest
timeliness.
"As a direct result of this storm, all of the
cotton in these counties is ready or will be ready to be defoliated
and harvested within a week," says Goodman. "There is not
the capacity to harvest, to transport or to gin all of this crop
before the weather causes further quality losses. Even without
another storm, we are going to see significant losses in quantity
and quality of the crop because farmers just will not be able to get
it picked and to gins in a timely fashion."
