# Study: Fluorescent light clarifies relationship between heat stress and crop yield | College of Liberal Arts & Sciences | Illinois

> Illinois researchers reported that sun-induced chlorophyll fluorescence can detect heat stress in soybean leaves before visible damage appears. The signal is linked to lower yields and could be monitored by satellite.

## Why it matters

This is a research advance in crop monitoring with no direct supply effect yet, so it has little immediate price impact on soybeans.
