ARS agricultural engineer Dennis Flanagan (left) use a green dye to observe runoff patterns from simulated rainfall.An engineer examines and tests the properties of matter and the sources of power in nature, with the goal of making new, better and more useful structures, machines and other products. There are many different types of engineers. Those in agriculture include civil, industrial, genetic, electrical, mechanical, chemical, hydraulic, electronic and agricultural engineers. An agricultural engineer, for instance, creates and improves ways--often related to farm machinery--to produce more and better food and fiber for us.
