The mission of the Engineering and Wind Erosion Research Unit is to: develop science and technology to rapidly measure grain traits; improve grain storage and handling systems; and minimize wind erosion through studying physical processes and developing predictive models and erosion control systems. To help ensure adequate food supply for the growing global population and preserve the environment, care must be taken to sustain soil resources and air quality, and ensure the quality and minimize losses of harvested crops. A multidisciplinary team develops improved models and software, and conducts studies for better understanding of wind erosion using unique large scale and portable wind tunnel facilities; develops high speed sorters that select specific grain properties using imaging, acoustics, near-infrared spectroscopy, and other sensors; and uses a unique full-scale research grain elevator to study grain quality changes during storage and handling.
