Agricultural Engineering200 | 300 | 400 | Graduate Courses (Administered by the Department of Agricultural and Biosystems Engineering) 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 Objectives: 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 to systems for production, processing, storage, handling, distribution, and use of food, feed, fiber and other biomaterials, and management of related natural resources worldwide. To achieve this goal, the ABE Faculty, with input from curriculum constituencies, has established the following educational objectives for the agricultural engineering curriculum: 1. To produce graduates competent in methods of analysis involving use of mathematics, fundamental physical and biological sciences, engineering sciences, and in computational skills needed for their future practice of agricultural engineering. 2. To produce graduates with the skills necessary in the design process, including abilities necessary to think creatively, to formulate problem statements, to communicate effectively, to synthesize information, and to evaluate and implement problem solutions. 3. To produce graduates capable of addressing issues of ethics, safety, professionalism, cultural diversity, globalization, environmental impact, and social and economic impact in engineering practice. 4. To produce graduates prepared for successful careers, and for continuous professional and personal growth. 5. To produce graduates with an ability to gain knowledge and answer questions through experimentation. 6. To produce graduates who can work collaboratively and who have people skills needed for a productive and satisfying life. Graduates find employment in diverse ag- and bio-related industries and government agencies, and work in engineering design, development, testing, research, manufacturing, consulting, sales, and service. Professional engineering services are performed in the agricultural equipment industries, building and environmental control companies, grain processing and handling firms, soil and water resource agencies and biotechnology companies. Food industry employment is related to production of food products. Food and process engineers design, develop, implement, and evaluate food processing procedures and systems. 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 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 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). Minor work is also offered in agricultural systems technology for students in other graduate majors. See Agricultural Systems Technology. Prerequisite to major 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 31 and 27. For the degree doctor of philosophy, the corresponding numbers are 72 and 42. All PhD graduate students are also expected to have some teaching/extension experience. 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).
