NC State Plant Sciences Initiative Developing AI Resources for Agriculture

By Lily Burton

Researchers at North Carolina State University and the N.C. Plant Sciences Initiative (PSI) are working to bring artificial intelligence technologies to agriculture.

AI has many potential applications in agriculture. But the industry doesn’t currently have the same resources that have enabled AI development in other fields. NC State researchers are trying to change that.

Chris Reberg-Horton, the Platform Director for the PSI at NC State, is working with his team to collect images of weeds that will be used to teach AI-powered equipment to recognize them and differentiate them from other plants.

“We have a robot set up that drives across an area that has lots of different weed species planted in pots out there,” he said. “And so, we can image, right now, about 500 pots a day through that system.”

Reberg-Horton said existing high tech agricultural equipment has the potential to observe and deliver precise care for individual plants.

“What's been missing is the knowledge and intelligence of field conditions to be able to inform that smart equipment of what to do,” he said. “And so, I really think that, you know, AI, and specifically, computer vision is one of the missing pieces in that.”

Video: Why Huitlacoche (Corn Smut) is So Expensive | So Expensive

Huitlacoche, also known as the "Mexican truffle," is an edible fungus that forms on undeveloped corn ears and sells for as much as $40 a pound. Discovered by the Aztecs, the bulbous fungus has been consumed in Mexico for centuries and has recently become an increasingly popular specialty ingredient around the world.

However, the US has dedicated significant time and money to keeping its cornfields free of what they call "corn smut" and "the devil's corn." Huitlacoche forms naturally during the rainy season, but farmers can also inject the fungus into their cornfields to harvest the valuable "black gold". So why has Huitlacoche become so popular and what exactly makes it so expensive?
