Dr. Birrell's research focuses is concentrated in two areas (1) the development of sensors and controls that can be applied in advanced machinery control and in precision agricul- ture, and (2) Harvest technologies and biomass harvesting and logistics. Present projects include developing a real-time soil nitrate sensor system for precision nitrogen applica- tions, development of sensors based on dielectric measurements, industry sponsored combine harvesting projects and development of biomass harvesting systems.
