Hemp is the same species as marijuana (Cannabis sativa), and the only difference is a legal one: Plants with less than 0.3% of the chemical that gives users a “high”— tetrahydrocannabinol, or THC — are hemp, and anything over 0.3% THC is marijuana. CAES News
Burgeoning hemp industry faces growing pains 07/26/21 Maria M. Lameiras
When you buy something at the store, you have a pretty good idea of what you’re getting no matter where you buy it — a Coke is a Coke, Oreos are Oreos — and whether you buy them in Atlanta or Seattle doesn’t really change what you get. Farmers are in a similar position when they choose what to plant, but in the burgeoning field of industrial hemp, it turns out that things are much more complicated.

Grass in the Olympic Stadium developed by UGA-Tifton 07/23/21 Leigh Hataway
The Summer Olympics may be in Japan this year, but Team USA was on home turf when they took the field for today’s Opening Ceremony. The Japan National Stadium’s field is currently sodded with TifSport bermudagrass, developed in south Georgia. One of many grass varieties created and tested at the University of Georgia’s Tifton Campus, TifSport is a dense, medium- to fine-textured grass bred to withstand the high traffic sports fields see while tolerating herbicides.
At UGA’s College of Agricultural and Environmental Sciences, 2021 Borlaug Undergraduate Scholar Samantha Wegener discovered precision plant breeding — the combination of gene editing and engineering — which showed her a path to solving complicated issues to improve plant varieties. CAES News
UGA CAES student named 2021 Borlaug Undergraduate Scholar 07/01/21 Courtney Cameron
Samantha Wegener enrolled at the University of Georgia’s Tifton campus after earning her associate’s degree in biology from the Technical College of the Lowcountry in Beaufort, South Carolina. It was during her last semester in Beaufort that Wegener was introduced to the world of plant breeding.

Keep your lawn disease-free with these tips from UGA Extension 06/11/21 Tripp Williams
As warm-season turfgrasses continue to green up, diseases are rearing their ugly heads. The main culprit this time of year is a fungus, Rhizoctonia solani, that causes large patch disease in lawns. Large patch can infect all warm-season turfgrasses, but centipede, St. Augustine, and zoysia are particularly susceptible.
A DSSAT training workshop that draws international participation is held on the University of Georgia Griffin campus each year. This year, 35 researchers attended the workshop, held from May 17 to 21, to learn the latest version of the precision agriculture software. CAES News
Computer software helps solve what-if questions in agriculture 06/10/21 Ashley N Biles
Anyone familiar with agriculture knows that a successful harvest largely relies on environmental factors. An especially hot summer with no rain in sight or poor soil quality can cause as many problems as a late cold snap right in the middle of planting season. Often farmers must rely on trial and error to get the best results. But for agricultural scientists, the guessing game can be reduced thanks to a computer software program called Decision Support System for Agrotechnology Transfer (DSSAT).
UGA Weather Network Director Pam Knox checks one of the data-logger boxes maintained by the network. All of the observational instruments connect to the data-logger, which collects and transmits weather data at 15-minute intervals, which is then disseminated through the UGA Weather Network website.

UGA Weather Network celebrates 30 years of service to agriculture in Georgia 06/01/21 Pam Knox
On June 1, 1991, the first agricultural weather station operated by the University of Georgia began transmitting data from Griffin, Georgia. Since then, the UGA Weather Network has grown to include 87 stations scattered across the state, providing weather data to a variety of users. On June 1 this year, this 30-year record of continuous weather data makes the UGA Weather Network one of the oldest state weather networks in the country.
