Undergraduate Study

For the undergraduate curriculum in agricultural engineering leading to the degree bachelor of science, see College of Engineering, Curricula. This curriculum is accredited by the Engineering Accreditation Commission of ABET.

Agricultural Engineering Curriculum Educational Goal, Objectives, and Learning Outcomes: The goal of the curriculum in agricultural engineering is to train students to integrate basic physical and biological sciences with engineering design principles to solve problems related to production, processing, storage, handling, distribution, and use of food, feed, fiber and other biomaterials, and the management of related natural resources worldwide.

The agricultural engineering bachelor of science degree program has the following educational objectives for its graduates. Two to five years after graduation, through the professional practice of engineering, graduates should:

1. Have demonstrated competence in methods of analysis involving use of Mathematics, fundamental physical and biological sciences, engineering sciences, and computation needed for the practice of biological systems engineering in food, fiber, energy and environmental companies and agencies.

2. Have developed skills necessary to the design process; including the abilities to think creatively, to formulate problem statements, to communicate effectively, to synthesize information, and to evaluate and implement problem solutions.

3. Be capable of addressing issues of ethics, safety, professionalism, cultural diversity, globalization, environmental impact, and social and economic impact in engineering practice.

4. Have demonstrated continuous professional and technical growth, with practical experience, so as to be licensed as a professional engineer or achieve that level of expertise

5. Demonstrated the ability to:

a. be a successful leader of multi-disciplinary teams, b. efficiently manage multiple simultaneous projects,

c. work collaboratively,

d. implement multi-disciplinary systems-based solutions,

Graduates find employment in diverse ag- and bio-related industries and government agencies dealing with agricultural machines and buildings, animal and environmental control, grain processing and handling, soil and water resources, food, and biotechnology. Their work involves engineering design, development, testing, research, manufacturing, consulting, sales, and service.The department has cooperative programs established for interested and qualified students. The four-year curriculum is extended over a five-year period and interspersed with work periods at cooperating organizations. This plan offers valuable practical experience and financial assistance during the years in college

The department also offers a bachelor of science curriculum in biological systems engineering. See College of Engineering, Curricula. Additionally, the department offers bachelor of science curricula in agricultural systems technology and in industrial technology. See College of Agriculture and Life Sciences, Curricula.

Well-qualified juniors and seniors in agricultural engineering who are interested in graduate study may apply for concurrent enrollment in the Graduate College to simultaneously pursue a bachelor of science degree in agricultural engineering and a master of science degree in agricultural engineering. Refer to Graduate Study for more information.

Graduate Study

The department offers work for the degrees master of science, master of engineering, and doctor of philosophy with a major in agricultural engineering, and offers minor work for students in other majors. Within the agricultural engineering major the student may specialize in:

- advanced machinery engineering (agricultural safety and health, sensors and artificial intelligence, controls and automation, precision agriculture, and biorenewables)

- animal and plant production engineering (air emissions measurement and abatement, animal welfare, environmental control in animal housing, manure treatment, crop modeling, plant stress physiology, precision agriculture, and decision support systems)

- environmental stewardship engineering (erosion control, drainage/water management, pollutant fate and transport, nutrients management, wetlands, vegetated filter/buffer strips, hydrological/water quality/crop modeling, geographic information science (GIS)

- remote sensing, water quality, and watershed management, or

- process engineering for food safety and value addition (processing technologies and systems for adding value, quality management systems, agricultural product, marketing practices and standards, instrumentation for grain, seed, and food quality enhancement).

A prerequisite to graduate work is the completion of an undergraduate curriculum substantially equivalent to that required of agricultural engineering undergraduate students at this institution. However, because of the diversity of interests within the graduate programs in agricultural engineering, a student may qualify for graduate study even though the undergraduate training has been in a discipline other than agricultural engineering. Supporting work will be required depending on the student's background and area of interest with requirements defined by departmental graduate student guidelines: www.iastate.edu/grad_students.asp

Well-qualified juniors and seniors in agricultural engineering who are interested in graduate study may apply for concurrent enrollment in the Graduate College to simultaneously pursue a bachelor of science degree in agricultural engineering and a master of science degree in agricultural engineering. Under concurrent enrollment, students are eligible for assistantships and simultaneously take undergraduate and graduate courses.

For the master of science program, at least 30 credits of acceptable graduate work must be completed with a minimum of 22 credits of course work; corresponding numbers for the master of engineering program are 32 and 27. For the doctor of philosophy degree, at least 72 credits of acceptable graduate work must be completed with a minimum of 42 credits of course work. All Ph.D. students must complete a teaching/extension experience prior to graduation.

The department also offers both master of science and doctor of philosophy degrees in industrial and agricultural technology (see Graduate Majors).

The department also participates in interdepartmental majors in environmental science, sustainable agriculture, biorenewable resources and technology, human and computer interaction, and toxicology (see Index).
