Agricultural engineers apply knowledge of engineering technology and science to agriculture and the efficient use of biological resources. (See biological scientists and agricultural and food scientists elsewhere in the Handbook.) They design agricultural machinery and equipment and agricultural structures. Some specialize in areas such as power systems and machinery design; structures and environment engineering; and food and bioprocess engineering. They develop ways to conserve soil and water and to improve the processing of agricultural products. Agricultural engineers often work in research and development, production, sales, or management.

Agricultural engineers are expected to have employment growth about as fast as the average for all occupations through 2014. The growing interest in worldwide standardization of agricultural equipment should result in increased employment of agricultural engineers. Job opportunities also should result from the need to feed a growing population, develop more efficient agricultural production, and conserve resources.
