Objectives
The biological and agricultural engineering program prepares students for professional engineering careers relating to the production and processing of agricultural and biomass materials for food, non-food, and fiber products while conserving natural resources and protecting our environment. It is our goal to give students the best possible education toward that end within the Accreditation Board for Engineering and Technology (ABET) program criteria for biological and agricultural engineering.

Biological and agricultural engineers provide an essential link between the biological sciences and engineering, which uses physical science to solve practical problems. Engineering fundamentals are applied to achieve the goal of a safe and stable food supply while considering human and environmental factors. Four curriculum options are available.

General option
Biological and agricultural engineers develop techniques and equipment for using land and water resources to produce and process an array of biological products, including food, fiber, energy, chemical feedstocks, and pharmaceuticals. The increasing demand for agricultural products must be met within the constraints of greater competition for reduced land, water, and energy resources.

Balancing the conflicting needs of society will require engineers trained to apply engineering science in the control and management of biological processes. The first two years of study in the general option concentrate on mathematics, physical sciences, and biological sciences. The third and fourth years contain additional engineering science courses as well as a broad range of technical elective courses that allow the student to pursue his or her specific interests.

Environmental option
Biological and agricultural engineers work at the interface between biology and engineering. They must be knowledgeable in both disciplines. Applications in the environmental option include water quality studies of lakes, rivers, and groundwater, soil and water conservation, irrigation and drainage, system design and management, waste treatment, management of air quality inside buildings and outside, remediation of land damaged by construction, mining, and other uses.

The environmental option focuses on the design and management of systems that use or impact natural resources. Non-point pollution issues have long been a component of agricultural engineering programs. Soil conservation programs began in the 1930s, long before the environmental movement began. Point and non-point pollution sources still impact the environment, requiring biological and agricultural engineering expertise to develop solutions to those problems. This option is distinct from but interfaces with the environmental option in civil engineering.

Secondary major in natural resources and environmental sciences
Students enrolled in biological and agricultural engineering, regardless of option, may participate in the natural resources and environmental sciences secondary major. Courses used for the secondary major may also be used for completing regular graduation requirements. Details are found in the Natural Resources and Environmental Sciences section of this catalog.

Processing option
Students pursuing the processing option can fulfill the requirements for a B.S. in biological and agricultural engineering with an emphasis on the processing, storage, and handling of biological products. Inherent in this program is the basic background of biological and agricultural engineering. The first three years of this option are similar to the other three options. Processing systems based electives from biological and agricultural engineering, chemical engineering, grain science, or animal science courses are selected from prepared lists to help students customize an engineering degree in their area of interest.

Machinery option
Many biological and agricultural engineers design, test, and evaluate the machines used in agriculture, construction, and related off-highway industries. The machinery option provides graduates with the analytical tools needed to develop machines that reduce the cost of production for both traditional and new crops, while operating within environmental and energy constraints. This option includes courses that emphasize mechanical design as well as the interaction of machines with soil and plant materials. Related technologies such as fluid power, instrumentation, and electronic controls are also included in this option.
