College Station, Texas
July 20,
2005While South Texas
farmers are bracing for the possible damage that Hurricane Emily
could inflict, many of the agricultural producers in other areas
of the state will welcome the moisture, according to Texas
Cooperative Extension agricultural experts.
"I've heard two scenarios: At the end of last week some farmers
were going to apply a defoliant to the cotton and try to harvest
as quickly as possible (before Hurricane Emily hit)," said Manda
Cattaneo, cotton Integrated Pest Management entomologist at the
Texas A&M University System
Agricultural Research and Extension Center in Weslaco.
"If they couldn't get it done in time, they were going to leave
(the cotton) and let the leaves protect it from the wind and
rain." But, Texas' overall average rainfall for April to June
2005 was the third driest in 110 years, said Texas State
Climatologist John Nielson-Gammon.
"June was the fifth driest June over the same period, comparing
unfavorably to last year's wettest-ever-June," Nielson-Gammon
said. "June also was driest-ever for the climate divisions
covering Central and Southeast Texas."
While West and East Texas received 2 to 4 inches of rain in
early July, the central and southern portions of Texas remained
dry.
"As a result, much of Texas is experiencing drought," he said.
"Dry conditions have been present in the lower (Rio Grande)
Valley since the beginning of the year. The dryness is spread
northward, thanks to a very dry June, and San Antonio recently
experienced its tenth longest spell ever of no measurable rain."
All of Central Texas is experiencing a lack of rainfall. He said
the North Texas counties between Interstate 20 and the Red River
are more than 10 inches below their normal year-to-date
rainfall.
"The dryness has been caused by a general lack of typical
springtime weather," said Nielson-Gammon. "The storm track
generally stayed well to the north of Texas, leading to few
tornadoes, as well as less rain, in general. As we enter July,
the weather regime shifts to a summertime pattern, which
typically brings scattered thunderstorms and an occasional
tropical disturbance."
Tropical rains during the past week brought temporary relief to
some areas.
"Ordinarily, drought at this time of year would not be expected
to improve significantly without a good tropical disturbance or
two bringing decent rainfall over a wide area," he said. "Such
events are impossible to predict far in advance, but one such
possibility is (Hurricane) Emily. Otherwise, there is no useful
forecasting guidance to predict the continuation or termination
of the drought."
According to the burn ban map located on the Texas Interagency
Coordination Center Web site,
http://www.tamu.edu/ticc/,
135 Texas counties have established outdoor burn bans. A few of
these counties lie in Hurricane Emily's path.
"Burn bans are a ban on outdoor burning, said Wayne Hamilton,
director of the Texas Agricultural Experiment Station's Center
for Grazinglands and Ranch Management. "They are put into effect
when weather conditions dictate to the county commissioners —
usually through information furnished by Texas Forest Service or
Texas Department of Agriculture — there is a high risk of
wildfire. These conditions are normally associated with drought
and accumulation of fine fuel like grasses and weeds from
preceding wet weather. As you can imagine, this year is an
excellent example of these kinds of conditions."
A county burn ban restricts outdoor burning only in
unincorporated portions of a county. Generally, bans are put
into effect to help prevent accidental fire starts due to debris
burning.
"Careless burning of household trash, brush piles and other
debris constitutes the number one cause of wildfires in much of
the state, so by preventing outdoor burning, a significant
source of potential wildfire starts can be avoided," said Mahlon
Hammetter, fire prevention specialist for the Texas Forest
Service in Lufkin.
Hammetter said the impact of the ban is determined on how the
commissioners word it.
"Sometimes the bans apply to any fires outside of a container
that contains all sparks and flames," he said. "Sometimes a ban
is worded to allow those exemptions to outdoor burning listed by
the Texas Commission on Environmental Quality. It just depends
on how the individual counties want to word their ban. Also, the
length of a ban and the penalties for violation of a ban differ
according to the legislation cited in establishing the ban."
Steve Livingston, Extension agronomist in Corpus Christi, said,
"The Forest Service usually calculates a drought index from
remotely accessed weather stations."
If the index is above 500, a burn ban is recommended.
The following livestock, crop and weather conditions were
reported by Extension districts:
PANHANDLE: Soil moisture short to adequate. Temperatures
were average to above average for the week. Isolated
thunderstorms were reported. Corn is beginning to tassel and is
rated fair to good. Corn borer moth emergence is under way in
the southern corn production areas of the district. Banks grass
mites are beginning to increase. Cotton ratings range from poor
to excellent; cotton fleahoppers are the major pest, but Lygus
bungs, cotton aphids, and beet armyworms are reported. Peanuts
are rated fair to good with no major insect or disease problems.
Dryland peanuts need rain. Sorghum is rated mostly fair to good
and need rain. Soybeans are rated fair to good. Some sunflower
fields are in bloom. Insecticide applications are being made for
the sunflower moth. Wheat harvest was coming to a close. Cattle
are in good body condition.
SOUTH PLAINS: Soil moisture is short. Hot and dry
conditions prevailed. Cotton was rated fair to good; early
fields began to bloom. Corn was in good condition. Irrigation
continued. Peanuts were rated good; most were pegging. Sorghum
and sunflowers progressed well. Pumpkins were in good condition.
Pastures and rangelands were rated fair to good. Cattle were in
good condition.
ROLLING PLAINS: Soil moisture is short. Showers were
reported. Forages responded positively to moisture. Livestock
were in good condition. Producers moved cattle and are getting
ready for fall calving season. Horse breeding came to a close.
Wheat producers prepared for fall planting. Cotton producers
fought sand. Alfalfa fields did well under irrigation.
Landscapes fought leaf spot disease on shrubs and trees.
NORTH: Soil moisture is very short to adequate. Hay and
livestock producers have better outlooks after rain was
received. Livestock demands at sale barns continue to be strong.
Sweet potatoes are responding well to rain. Weather is mostly
hot and dry. The region needs more rain.
EAST TEXAS: Soil moisture is short. Scattered rainfall
was reported. Pasture conditions improved; some hay was cut.
Many producers fed hay. Most counties enacted burn bans. Fruit
crops had good yields. Cattle were in good condition.
FAR WEST: Soil moisture is short. Some scattered showers
and very hot temperatures were reported. Pastures, rangelands
and livestock were rated poor to good; some cattle were fed
supplements. Cotton set boles and was squaring.
WEST CENTRAL: Soil moisture is very short. Hot and dry
conditions were reported. All crops showed signs of heat stress;
most fields need rain before cultivation can occur. Hay harvest
ended. Some was too dry to bale. Cotton did well. Producers
sprayed for weed control. Rangelands and pastures dried up fast
due to drought conditions. Irrigated pecan orchards did well.
CENTRAL: Soil moisture is short. Pastures need rain.
Cattle body condition scores dropped earlier and faster than
normal. Some late planted corn was grazed out. Second generation
weevils emerged in cotton crops. Insecticide applications may be
warranted.
SOUTHEAST: Soil moisture is short to adequate. Scattered
thunderstorms were reported. Cloud coverage increased, but
temperatures were still high. The area watched for Hurricane
Emily. Brazoria County reported 45 days without rainfall.
Soybean pods were not filling completely due to drought stress.
Hay yields were poor. Rains improved pastures and rangelands.
SOUTHWEST: Soil moisture is short. Light rain and cooler
temperatures were reported. Production remained under stress.
Pastures, rangelands and yard grasses were grown and in
mid-summer dormancy. Forage availability was below average.
Cotton, peanuts and cucumbers made good progress under heavy
irrigation. Watermelon, cantaloupe and cucumber harvest
continued. Sorghum and corn harvest gained momentum.
COASTAL BEND: Soil moisture is short. Extremely hot and
dry conditions were reported. Lack of moisture had an adverse
effect on cotton yields and fiber development. Some fields will
receive harvest aid. Sorghum harvest was in full swing. Cattle
were in fair to good condition.
