In Illinois, a research project is exploring how cover crops can help manage soybean cyst nematode (SCN) populations. SCN is a common pest that affects soybean yields and farmer profits. To find better solutions, researchers have set up 13 study sites across the state where different cover crops have been planted.
Dr. Jason Bond, who is leading the project, shared updates on its progress. The team is currently examining soil samples collected in the fall and early winter. These samples include data from trials that began in fall 2023 and new trials started in fall 2024.
The goal is to track SCN levels in each plot and see how cover crops influence the pest.
In addition to counting nematodes in the soil, the researchers are using advanced DNA sequencing techniques. By studying the soil’s microbiome, or microbial life, they hope to understand how different cover crops may suppress SCN or improve soil health overall.
This work is being funded by the Illinois Soybean Checkoff and is designed to support soybean farmers across the state. By learning which cover crops are most effective, the project aims to provide practical guidance to help farmers protect their crops naturally and sustainably.
Over the coming weeks, the team will continue to collect spring soil samples, analyze the data, and refine their understanding of cover crop impacts. Their findings will offer new tools for SCN management and may help reduce the need for chemical treatments in soybean fields.
By combining field trials with cutting-edge science, this project is helping to shape the future of sustainable soybean farming in Illinois.
