A discipline concerned with solving the engineering problems of providing food and fiber for the people of the world. These problems include designing improved tools to work the soil and harvest the crops, as well as developing water supplies for agriculture and systems for irrigating and draining the land where necessary. Agricultural engineers design buildings in which to house animals or store grains. They also work on myriad problems of processing, packaging, transporting, and distributing the food and fiber products. Agricultural engineering combines the disciplines of mechanical, civil, electrical, and chemical engineering with a basic understanding of biological sciences and agricultural practices. Some agricultural engineers work directly with farmers. Most, however, work with the companies that manufacture and supply equipment, feeds, fertilizers, and pesticides. Others work for companies that provide services to farmers, such as developing irrigation and drainage systems or erecting buildings and facilities. Still others work with food-processing companies.
