It is a good idea to work on a ranch or farm through a job or internship. Belonging to a club like 4-H also provides valuable exposure to agriculture.
Many programs require you to go on field trips to places such as grain elevators, grocery warehouses, and animal processing plants. This allows you to see the world of agriculture and business firsthand.
For information about farm occupations, opportunities, and 4-H activities, contact your local county extension service office.
