Agricultural Engineering: courses, careers, and where to study

Agricultural engineering applies engineering design to farming and food systems, fitting students who want to build the machinery, water systems, and facilities behind food, feed, and fiber.

Agricultural engineering brings engineering design to the production and handling of food, feed, and fiber. Students learn to apply math, physics, and biology to the machines, structures, and systems that grow crops, raise animals, and move harvests from field to market. Coursework spans the strength and motion of machinery, the flow and storage of water, soil behavior, the design of barns and grain facilities, and the equipment used to clean, dry, and process raw products. Many programs add a biological-systems track that treats living plants and animals as part of the engineered system, which is why some departments use the name biosystems engineering. Unlike agronomy or animal science, which study the crops and livestock themselves, agricultural engineering focuses on designing and evaluating the hardware, water systems, and facilities that make production work; and unlike broad environmental engineering, its center of gravity sits squarely on agricultural land, irrigation, and the food supply chain.

The standard credential is a bachelor's degree, built on a sequence of calculus, physics, chemistry, and engineering science, with hands-on labs in fluid mechanics, soil and water, and machine design, and usually a senior capstone in which teams design and test a real piece of equipment or a water-management system. Students who plan to offer engineering services to the public or sign off on designs typically pursue professional engineering licensure, which generally involves a fundamentals exam taken near graduation, supervised work experience, and a later practice exam; whether a given program meets the educational requirement for licensure should be verified directly, and programmatic accreditation may also matter for that path. Graduates work for equipment and machinery manufacturers, irrigation and drainage firms, food and grain processors, soil and water conservation agencies, and consulting practices, often splitting time between field sites, fabrication shops, and the design office.

In federal data for the closely related occupation of agricultural engineers, the U.S. Bureau of Labor Statistics reports a 2024 median wage of $84,630 and projects employment to grow about 5.9% from 2024 to 2034; a bachelor's degree is the typical entry-level education for that occupation. National figures are occupation-wide medians across all experience levels, not starting wages or graduate outcomes.
