Department of Soil and Water Systems
Soil and water systems
The Department of Soil and Water Systems (SWS) combines soil science, agronomy, hydrology, sediment transport, irrigation engineering, waste management and precision agriculture. You’ll learn to address resource issues related to soil, water quality and quantity and sustainable food, energy and waste systems. Experiential learning and opportunities outside of the classroom will help you build professional skills and opportunities to network with field and industry professionals.
As a student in SWS, you’ll learn about issues in soil, water and environments in urban, agricultural and natural ecosystems.
In the agricultural systems management program, you’ll gain knowledge in managing machines and equipment, biological processes and other technologies to create new and improved agricultural systems. This hands-on program involves experience in shop practices, welding, electric power, machinery and small engines.
In the environmental soil science degree, you'll apply knowledge in biology, chemistry and physics to conserve and improve soil and water quality for farming, bioremediation, development and more. Gain the interdisciplinary knowledge required to manage crop, forest, rangeland and urban soils for long-term health and sustainability with this degree.
The sustainable food systems degree is perfect if you’re interested in producing food while conserving natural resources such as soil and water. Learn about new production practices and gain an understanding of how policy influences the availability of food. Then, put the knowledge you learn in the classroom into practice at our organically managed student farm close to campus.
In the water science and management degree, you’ll study water quality and quantity issues and learn to use science to manage and conserve water in various environments.
Minors in agricultural systems management, soil science, sustainable food systems and water science and management are available to complement any major. A certificate in precision agriculture provides further education related to technologies used to help ensure a safe and sustainable food supply while reducing environmental impacts.
Academics
Explore degree options to see which option is right for you. Whether you're interested in developing new technologies to aid food production, improving soil and water quality, producing food with less resources or studying water quality and quantity issues, we’ll supply you with knowledge to address critical issues to help sustain our natural resources for the future.
SWS also offers a master’s and doctorate program in soil and land resources. Interdisciplinary programs in water resources and environmental science are also available. In these programs, you'll work with professors who actively conduct research on a variety of topics and customize your program based on research interests.

Soil Stewards Farm
The Soil Stewards Farm gives you an opportunity to learn and practice the principles of sustainable, small-acreage market garden production. You’ll gain important hands-on experience and leadership skills through the operation of the certified organic farm.
Produce grown at the farm is sold to the local community. Available produce will vary depending on the season, but the Soil Stewards grow diversified vegetables from greens to tomatoes, kale, onions, potatoes, pumpkins and more. Check our Facebook or Instagram to stay up to date on plant sales, produce sales and other updates.
The Soil Stewards Farm is located on a three-acre parcel on Farm Road near the U of I Sheep Center. The farm was certified organic in 2020.
