Agricultural & Biosystems Engineering

Are you looking to improve our quality of life, protect the environment, and help meet the needs of a growing world population? As an agricultural and biosystems engineer, you might be asked to use your knowledge of biology and engineering to develop plant-based products like medicines, biodegradable packaging, and biomass energy; or design methods of keeping harmful microorganisms out of our food supply; or redevelop streams in areas impacted by mining, urban, and agricultural activities. In this rewarding career, you’ll be constantly innovating to meet the needs of humankind in sustainable ways.

Meet Gayle, an agricultural engineer who works to improve farming practices. She thinks about manure on a daily basis!

Can Woodchips Help The Gulf Of Mexico’s Dead Zone?

“Denitrifying bioreactor” may sound like a high-tech operation, but it’s in fact a nature-based solution to one of the problems that result from our efforts to get the best yield from the crops we grow. When agricultural nutrients are applied to crops, not all of them are absorbed by the plant; excess can run off and make their way into streams and rivers. To address this problem, agricultural engineers are using wood chips placed strategically in farmland. The wood chips are home to naturally occurring bacteria that break down the nutrients before they can infiltrate waterways.

Turning Pollutants into Food

Reduce, reuse, recycle—these are the underlying imperatives of sustainability. Biosystems engineers at Auburn University are doing their part by turning farm wastewater into fish food. Using a process that involves bacteria, algae, and photosynthesis, the engineers convert nutrient pollutants in manure wastewater into protein-rich fish food. In addition to the aquacultural benefits, the innovative process is good for the environment because it reduces reliance on the specially designed manure-storage lagoons, which are odorous and can overflow in severe rainfall events.
