K-State researchers are advancing AI-powered crop pest detection.

Researchers at Kansas State University (K-State) are testing the Insect Eavesdropper, a technology that uses microphones, artificial intelligence, and data analysis to detect hidden insect activity in crops. The system could help farmers identify pest problems earlier and improve crop monitoring.

Graduate student Emily Sur is leading field research that involves placing microphones on soybean plants to record insect sounds and vibrations. Researchers then compare the recordings with plant inspections to determine how effectively the technology detects pests.

“I've always enjoyed being outdoors, so that's one of the things that drew me to this project, getting to work outside in the fields,” said Sur.

The project is part of a multistate collaboration led by Emily Bick of the University of Wisconsin-Madison. The technology captures vibrations produced by insects feeding or moving inside plants, helping identify pests that are often difficult to see through traditional scouting methods.

At K-State, Sur works with Brian McCornack and other researchers to test the system under real farming conditions. Much of the research has focused on the soybean stem borer, a pest that is hard to detect because it tunnels inside plant stems.

“By using this new tool, we can detect these insidious invaders without needing to sacrifice plants,” McCornack said.

Researchers combine expertise in entomology, engineering, artificial intelligence, and data science to analyze large amounts of sound data. Their goal is to create a practical tool that provides continuous crop monitoring and supports better pest-management decisions.

The project is also giving students hands-on experience with research, technology, and problem-solving. Participants gain valuable skills in data collection, troubleshooting, and interdisciplinary collaboration.

By combining agriculture and advanced technology, the Insect Eavesdropper could help farmers detect hidden crop threats sooner and respond more effectively. Researchers believe the system has strong potential to improve crop health monitoring and support sustainable agricultural production.

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
