Agricultural Engineer


Agricultural engineers solve problems concerning power supplies, machine efficiency, the use of structures and facilities, pollution and environmental issues, and the storage and processing of agricultural products.

What they do

Agricultural engineers typically do the following:

  • Use computer software to design equipment, systems, or structures
  • Modify environmental factors that affect animal or crop production, such as airflow in a barn or runoff patterns on a field
  • Test equipment to ensure its safety and reliability
  • Oversee construction and production operations
  • Plan and work together with clients, contractors, consultants, and other engineers to ensure effective and desirable outcomes

Agricultural engineers work in farming, including aquaculture (farming of seafood), forestry, and food processing. They work on a wide variety of projects. For example, some agricultural engineers work to develop climate control systems that increase the comfort and productivity of livestock whereas others work to increase the storage capacity and efficiency of refrigeration. Many agricultural engineers attempt to develop better solutions for animal waste disposal. Those with computer programming skills work to integrate artificial intelligence and geospatial systems into agriculture. For example, they work to improve efficiency in fertilizer application or to automate harvesting systems.

Work Environment

Agricultural engineers typically work in offices, but may spend time at a variety of worksites, both indoors and outdoors. They may travel to agricultural settings to see that equipment and machinery are functioning according to both the manufacturers’ specifications and federal and state regulations. Some agricultural engineers occasionally work in laboratories to test the quality of processing equipment. They may work onsite when they supervise livestock facility upgrades or water resource management projects.

How to become an Agricultural Engineer

Agricultural engineers must have a bachelor’s degree, preferably in agricultural engineering or biological engineering.

Students who are interested in studying agricultural engineering will benefit from taking high school courses in math and science. University students take courses in advanced calculus, physics, biology, and chemistry. They also may take courses in business, public policy, and economics.

Entry-level jobs in agricultural engineering require a bachelor’s degree. Bachelor’s degree programs in agricultural engineering or biological engineering typically include significant hands-on components in areas such as science, math, and engineering principles. Most colleges and universities encourage students to gain practical experience through projects such as participating in engineering competitions in which teams of students design equipment and attempt to solve real problems.


The median annual wage for agricultural engineers was $80,720 in May 2019. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $47,330, and the highest 10 percent earned more than $160,950.

Job Outlook

Employment of agricultural engineers is projected to grow 2 percent from 2019 to 2029, slower than the average for all occupations.

Farming establishments will continue to require more machinery, equipment, and buildings to increase the efficiency of agricultural production systems and to reduce environmental damage, which should maintain demand for these workers.

Agricultural engineers are expected to continue working on projects such as alternative energies and biofuels; precision and automated farming technologies for irrigation, spraying, and harvesting; and growing food in space to support future exploration.

More efficient designs for traditional agricultural engineering projects such as irrigation, storage, and worker safety systems will also maintain demand for these workers. Growing populations and stronger global competition will result in the industry needing more efficient means of production, which will increase demand for agricultural engineers.

Reducing pollution in a farm’s water supply… Improving the efficiency of a rural electric power system… Discovering a new way to extend the life of a tomato… These are some of the projects an agricultural engineer might work on in the quest to make agricultural operations as efficient and productive as possible. Most agricultural engineers work in offices, with frequent research visits to farms, labs or rural areas. They work for government offices, engineering firms, universities and manufacturers. The ultimate goal for these engineers is to improve crop and livestock production. This career focuses on the design and manufacture of the equipment and facilities needed to reach that goal. Agricultural engineers examine the impact of plant and food production on the greater environment, and look for ways to reduce negative impacts. Sometimes they even make news headlines with breakthroughs on production techniques, such as genetic engineering and cloning. Agricultural engineers need an aptitude for science and technology, along with good oral and written communication skills. They rely heavily on their ability to recognize and solve problems. A bachelor’s degree in agricultural or biological engineering is the entry-level education needed. As the world population continues to expand, the need for the work of agricultural engineers will only continue to grow.
