Agricultural Engineering Practice Exam

The term that describes an unplowed area where machinery turns around is "headland." Headlands are typically located at the end of a field and serve as a designated space for equipment, allowing farmers to maneuver their machinery without disturbing the crops or soil in the field. This unplowed area helps prevent soil compaction and potential damage to crops during harvesting and planting operations.

Headlands are essential for efficient field management, as they facilitate smoother transitions between passes of farm equipment. This is particularly important in large fields where turning space is necessary to maintain productivity and reduce wear on machinery. The other terms mentioned relate to different concepts in agricultural operations: field boundaries refer to the edges of a field, a turn row is often used to describe a row of planted crops that is specifically designed for turning machinery, and a harvest strip typically refers to a section of a field that is harvested.
