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 the Accreditation Board for Engineering and Technology. Agricultural Engineering Curriculum Educational Goal, Objectives, and Learning Outcomes: The goal of the curriculum in agricultural engineering is to train men and women to integrate basic physical and biological sciences through application of engineering fundamentals and design of systems for the 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 degree program has the following educational objectives for its graduates. Two to five years after undergraduate graduation, through the professional practice of engineering, graduates should have:

1. 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. 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. 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,

e. apply innovative solutions to problems through the use of new methods or technologies,

f. contribute to the business success of their employer, and

g. build community. The agricultural engineering degree program outcomes are statements that describe what our students are expected to know and be able to do by the time of graduation. To meet the established agricultural engineering program educational objectives, the expected outcomes of the BS Agricultural Engineering graduates are:

a) an ability to apply knowledge of mathematics, science, and engineering

b) an ability to design and conduct experiments, as well as to analyze and interpret data

c) an ability to design a system, component, or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability

d) an ability to function on multi-disciplinary teams

e) an ability to identify, formulate, and solve engineering problems

f) an understanding of professional and ethical responsibility

g) an ability to communicate effectively

h) achievement of the broad education necessary to understand the impact of engineering solutions in a global, economic, environmental, and societal context

l) proficiency in mathematics through differential equations

m) proficiency in biological and engineering sciences

n) competence in the application of engineering to agriculture, aquaculture, food, forestry, human, natural resource, or other biological systems. Graduates find employment in diverse ag- and bio-related industries and government agencies related to agricultural equipment, building animal and environmental control, grain processing and handling, soil and water resources, food, and biotechnology. They work in areas that include 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 an undergraduate curriculum and courses in agricultural systems technology, see College of Agriculture, 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 both B.S. and M.S. degrees. Refer to Graduate Study for more information.

Graduate Study

The department offers work for the degrees in master of science, master of engineering, and doctor of philosophy with a major in agricultural engineering and minor work to students taking major work in other departments. Within the 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 or seniors in agricultural engineering who are interested in graduate study may apply for concurrent enrollment in the Graduate College to simultaneously pursue both B.S. and M.S. degrees. 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 PhD graduates are also expected to have completed some teaching/extension experience prior to graduation.

The departments also offers a masters of science and doctor of philosophy in industrial and agricultural technology, see College of Agriculture, Curricula.

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