Sustainable Plant Systems

Agronomy Option

Discover plant systems that maximize production, conserve resources and minimize environmental damage with coursework from basic and applied plant and soil science in small classes and hands-on training. Students focus on developing low-water use and disease-resistant plants that maximize crop yield and plant health in fields where land size constrains production.
