What you earn and what it costs to get there.
Median
$98,590
Entry engineer
$68,060
Senior or consulting
$166,460
The national median is $98,590 a year, and the bottom tenth start near $68,060. It is one of the smallest engineering occupations in the country, which means fewer jobs but also very little competition for the ones that exist.
$68,000 to $80,000
First engineering role out of a four year degree
Equipment manufacturers and food processing companies pay at the top of that band. Government agencies and conservation districts pay less but offer a pension and Public Service Loan Forgiveness.
$166,460
Senior engineers, consultants and design managers
The highest paid work tends to be either designing machinery for a major manufacturer or running your own consulting practice on irrigation, drainage and manure systems for large farms.
Tuition, fees, exams and kit. Not rent, food or travel
The low end is two years at a community college then transfer into an in-state land grant university, plus the Fundamentals of Engineering exam in your final year. The high end is four years paid at the out-of-state rate those same universities charge non residents. The Principles and Practice of Engineering exam comes years later, after four years of work experience, and many agricultural engineers never need the license at all. Agricultural colleges hand out scholarship money that is far less competed for than general engineering money, so file the FAFSA (Free Application for Federal Student Aid) and then ask the college directly.
File the FAFSA (Free Application for Federal Student Aid) every year. Agricultural colleges hand out a lot of scholarship money and it is far less competed for than general engineering scholarships.
Paid internships
Equipment makers and food companies run summer programs, and most graduates are hired from them.
Field travel
You will not be at a desk every day. Site visits to farms, plants and project sites are part of the work.
Government pensions
Federal and state conservation agencies hire agricultural engineers and still offer defined pensions.
Retirement savings with a match
A 401(k) plan where the employer adds money on top of yours, standard in private industry.
The exact path from high school to qualified.
A normal engineering degree, taken in an agricultural college.
High school
Grades 11 and 12
Calculus, physics, chemistry and biology. Farm or shop experience is genuinely useful here in a way it is not in most engineering fields.
Bachelor's degree
4 years
Agricultural, biological or biosystems engineering, accredited by ABET (the accrediting body for engineering degrees in the United States). Purdue, Iowa State, Nebraska and Texas A&M all run large accredited departments.
Internships
Summers
A summer at an equipment manufacturer, a food plant or a conservation agency. This is how people get hired.
First engineering job
Year 1
Design, testing or project work under a senior engineer.
Professional Engineer license, if your work needs it
4 or more years
The Fundamentals of Engineering exam, four years of experience, then the Principles and Practice of Engineering exam.
Calculus and physics
The core of any engineering degree, and the entry requirement.
Biology
This field is engineering applied to living systems: soils, crops, animals, food.
Agriculture or shop
If your school has an agriculture program, take it. Knowing how a farm actually works is an advantage.
Computer science
Sensors, controls and data analysis run modern agriculture.
Engineering licenses come from state boards, coordinated by NCEES (the National Council of Examiners for Engineering and Surveying), which covers 68 member boards. Agricultural engineers working for a manufacturer usually do not need one, because companies making products are exempt. You do need it if you design and stamp drawings for other people: drainage systems, dams, grain structures, manure lagoons, anything a county will inspect. If you think you might end up consulting, sit the Fundamentals of Engineering exam in your final year while the material is fresh.
Purdue University
One of the oldest agricultural and biological engineering departments, accredited, with undergraduate and graduate programs.
Iowa State, University of Nebraska-Lincoln, Texas A&M University
Large land grant programs sitting right next to the industry they feed.
Your state's land grant university
Every state has one, and its agricultural engineering department is tied directly to local employers.
Things you don't need, but that help.
Machinery design
Tractors, combines, planters and the automation inside them. The biggest employer group.
Soil and water
Irrigation, drainage and erosion control. This is where licensure matters most.
Food and process engineering
Getting a crop from field to package safely and at scale.
Structures
Grain bins, livestock housing, ventilation and storage.
Precision agriculture
GPS guidance, yield sensors, drones and the software that ties them together.
A summer on a farm or in a dealership
You learn what breaks and why, which is half of designing something better.
Computer-aided design
Expected from your first day in any design role.
Data skills
Python and basic statistics. Modern farm equipment produces enormous amounts of data.
A welding or machining class
Engineers who can build a prototype themselves are unusual and valued.
The United States Department of Agriculture and state conservation agencies hire agricultural engineers to design and approve soil, water and waste systems on farms. The pay is lower than industry, the projects are public, and the job security is high. These roles qualify for Public Service Loan Forgiveness, which cancels your remaining federal student loans after 10 years of payments while working for a government or nonprofit employer.
Day to day, pros and cons, where you'd work.
Half the field works like any other design engineer: modeling a component, checking stress, running a simulation, sitting in a review. The other half is out on sites, measuring a field's slope for a drainage plan, watching a prototype planter in real dirt, or walking a food plant line to find where product is being damaged. It is one of the few engineering careers where mud on your boots is a normal Tuesday.
The good
The hard parts
Things people don't tell you.
The American Society of Agricultural and Biological Engineers publishes the technical standards the farm equipment industry runs on. It is why an implement built by one company hitches to a tractor built by another.
There are far fewer agricultural engineers than civil or mechanical engineers in the United States. That makes job listings scarcer, but it also means a graduate from a good program is rarely unemployed for long.
GPS guided steering has been standard on large farm equipment for years, and manufacturers are now selling machines that run a field with no driver in the cab. Designing and validating those systems is agricultural engineering work.
Many universities renamed agricultural engineering as biological or biosystems engineering to reflect work in food, bioenergy and the environment. It is the same accredited degree, so search for both names when you look at schools.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
