High Quality Content by WIKIPEDIA articles! A Field day is a large trade show for agricultural industry and equipment, especially for broadacre farming. It contrasts with an agricultural show in that a show focuses on livestock and judging, a field day focuses on equipment, demonstrations and processes. A field day may include events such as ploughing competitions not usually associated with shows due to the larger space required. The events are good sources of agricultural information, as organizers can arrange for guest speakers to talk on a range of topics, such as the talk on the yellow-flowering alfalfa at the South Dakota field day. Pecan growers were given a talk on insect control by an entomologist at a recent field day at LSU AgCenter s Pecan Research/Extension Station in Shreveport, La.
