COLLEGE STATION – Sensor technology could possibly solve many challenges of crop production, and Texas A&M AgriLife Research faculty are aggressively attempting to find new solutions.
Dr. Alex Thomasson, an AgriLife Research biological and agricultural engineer, and Dr. Seth Murray, AgriLife Research corn breeder, both in College Station, and others are working jointly on several projects.
One project, an unmanned ground phenotyping system, provides data that can be used to aid decisions in breeding and production agriculture through techniques like conceptual modeling and spatial prediction, according to the scientists.
“We can also look at other characteristics like the drought tolerance of the plant. The data these machines collect will ultimately enable the breeder to make selections from the best varieties and to do so much quicker.”
Thomasson and other AgriLife and U.S. Department of Agriculture scientists are developing the ability to use remote sensing to detect and treat cotton root rot. Cotton Incorporated has been a strong supporter of this research, some of which is occurring at the Stiles Farm at Thrall.
“The cotton root rot project involves a lot of remote-sensing work to detect the locations of infection within individual fields,” he said. “It’s expensive for cotton farmers, not only the yield losses from the disease but the treatment to prevent it. It’s costing them about $50 an acre to treat the fields, but this research can save them a lot of money by enabling them to treat only the infected areas of a field. Some are trying to use satellite data to identify infected areas, but the image resolution is low. We’ve begun using UAVs (unmanned aerial vehicles), which give us images with extremely high resolution. We have the potential to see where each infected plant is so we can know exactly where to place fungicide in subsequent seasons.”
The remote-sensing research is related to a broader scope of research projects implemented by AgriLife Research. The Texas A&M Coordinated Agricultural Unmanned Aerial Systems project and Ground Vehicle Validation is a collaboration of more than 40 faculty members within the Texas A&M University System.

Led by AgriLife Research, the project also involves the Texas A&M Engineering Experiment Station, the Center for Autonomous Vehicles and Sensor Systems, and the Center for Geospatial Applications and Technologies, as well as businesses and farmers. The research centers on 1,400 acres of AgriLife Research fields near College Station where corn, cotton, sorghum and wheat, as well as peaches and perennial grasses are grown.

With the prolonged drought, most pastures in Oklahoma end up in poor condition. With the lack of available forage, animals may go in search of alternative foods.
If oak trees are in the pastures, acorns may be a favorite meal for some livestock in the fall. This may result in oak poisoning.
Oak leaves, twigs, buds, and acorns may be toxic to some animals when consumed.

There are a handful of grasses on North Texas grazing lands ranchers need to know, not because they are highly desirable, but rather because they are not of much value. I call them “decom” plants, which is am acronym for “Don’t Ever Count On Me.” Silver bluestem is a “decom” grass.
Silver bluestem is a perennial which grows in all areas of Texas. It can survive in almost all soil types, and in full sun conditions or in semi shade. It grows up to three feet tall and is easily recognized with the presence of the white fuzzy seed head. Also, one of the identifying characteristics of Silver bluestem is a bend in the stems at each node, causing the plants to take on a rounded shape as they mature.

Fall is here which means winter is closing in on us and before we officially get into winter, we need to make sure our factories are either producing or will be producing in a few months.
We have been pregnancy testing our cows this fall and if they are not bred or nursing a calf, we are bidding them adios. With annual costs somewhere between $900.00 and $1,000.00 per cow, those cows not producing a live weaned calf are costing us quite a bit.
