LITTLE ROCK – The soybean harvest may still be more than two months out, but unseasonably
cool temperatures could propel some growers in the state toward a very strong harvest
Jeremy Ross, extension soybean agronomist for the University of Arkansas System Division
of Agriculture, said daytime high temperatures in the mid-80’s are likely to prove
a boon to the state’s No. 1 crop over the next week.
“Eighty-six degrees is optimal for soybean growth and development,” Ross said. “And
it doesn’t look like we’re going to get out of the mid- to upper-80’s. So as long
as a crop isn’t stressed with something else — nutrient stress or disease stress,
for example — we ought to finish out this crop pretty strong.”
According to forecasts from the National Oceanic and Atmospheric Administration, temperatures
in Arkansas have a 50-60 percent probability of remaining below the annual average
between now and Aug. 15.
Drying soils not an issue
Ross said daily temperatures are a more reliable bellwether for the 2017 soybean crop
than soil moisture readings, which are falling for much of the Midwest as the summer
approaches its peak. According to an Aug. 1 report from the U.S. Department of Agriculture’s
National Agricultural Statistics Service, about half of Arkansas topsoil moisture
supplies were “short” or “very short,” as were subsoil moisture readings.
Drought conditions are currently milder for Arkansans than some of their neighbors,
according to data from the U.S Drought Monitor, maintained by the University of Nebraska-Lincoln.
While about a third of counties in Missouri and Oklahoma find themselves in abnormally
dry or moderate drought conditions, less than 1 percent of Arkansas acreage is even
“It’s actually an improvement over some of our recent summers, if you discount 2016,”
2016 was an unusual mixture of weather conditions, to be sure — during the first week
of August, about 37 percent of Arkansas was under abnormally dry conditions, according
to the drought monitor, while other areas of the state sat under saturated soils,
resulting from 14 days of continuous rain.
By the final week of 2016, however, about three-quarters of the state was in abnormally
dry or moderate drought conditions, and about 7 percent of acreage in severe drought,
according to drought monitor data. But Ross said farming techniques commonly used
in Arkansas have helped negate the impact of dry weather and soil for much of row-crop
production in the state.
“We rely on a lot of irrigation in Arkansas, so I don’t get too worked up about topsoil
moisture,” Ross said.
Full impact of dicamba drift still to be seen
Ross cautioned that overall average yield for the state is still an open question,
as the full impact of off-target movement from off-label dicamba applications is still
unknown. Since Monsanto released new dicamba-resistant seed technologies in late 2015,
the Arkansas State Plant Board and similar institutions in neighboring states have
received hundreds of complaints of drift injury, as some growers chose to use the
herbicide in the absence of an authorized formulation, often damaging their neighbors’
soybean crops in the process.
In July, the Arkansas State Plant Board issued an emergency rule banning both the
sale and use of dicamba products in Arkansas.
Ross said U.S. I-40, the interstate highway that bisects much of the state between
north and south, may serve as a de facto demarcation line for the pesticide’s damage
to soybeans in the state.
“The southern part of the state hasn’t had the issues with off-target movement, so
the crop in the southern part of the state looks really strong,” he said. “We’re going
to have some pretty good yields coming out of southern Arkansas. Once you get north
of I-40, it’s still a big question about yield impact some of these off-taget movements
are going to have. Additionally, in northeast Arkansas, a lot of those fields were
delayed in planting, because of the flooding conditions in April and May.
“We’re really sitting on two different crops. The crop in the southern part of the
state looks really good,” he said. “The crop in the northern part has had some issues.”
