Biological and agricultural engineering refers to the incorporation of engineering principles and theories into natural systems to improve food, water, energy, machines and the environment. Research relevant education and career options here. 

Biological and agricultural engineering is the application of engineering principles to agriculture, food and biological systems. Agricultural engineers attempt to solve agricultural problems concerning power supplies, the efficiency of machinery, the use of structures and facilities, pollution and environmental issues, and the storage and processing of agricultural products. Biological engineers design systems for the biological materials used in products, including such as food and drugs. 

Education Information 

Agricultural and 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. 

Master’s and Ph.D. programs can qualify graduates for senior-level positions in chemical companies and government agencies. Alternatively, graduate degree programs can prepare individuals for careers in research or academia. 

Licensure is not required for entry-level positions as an agricultural engineer. A Professional Engineering (PE) license, which allows for higher levels of leadership and independence, can be acquired later in one’s career. Licensed engineers are called professional engineers (PEs). A PE can oversee the work of other engineers, sign off on projects, and provide services directly to the public. 


There are no biological and agricultural engineering programs specifically offered online. Some colleges and universities offer free courses online but these do not count for college credit. 

Career Options 

Biological and agricultural engineers work in a variety of different industries, including environmental consulting companies, colleges and universities, government agencies and biotechnology companies.

Employment Outlook and Salary Information 

Employment of agricultural engineers is projected to grow 8 percent from 2016 to 2026, about as fast as the average for all occupations. The need to increase the efficiency of agricultural production systems and to reduce environmental damage should maintain demand for these workers. The median annual wage for agricultural engineers was $77,110 in May 2018. Typically, graduates of engineering programs have good job prospects and can often enter related engineering fields in addition to the field in which they have earned their degree. Agricultural engineering offers good opportunities, but it is a small occupation, and engineers trained in other fields, such as civil or mechanical engineering, also may compete for these jobs. (
