Penton Media and Western Farm Press will publish the official World Ag Expo magazine and show guide in 2009.

The choice of publisher was announced today by Jerry Sinift, general manager of the International Agri-Center, where the expo is held each year.

The show guide is distributed at expo gates and includes a map and list of events during the show’s three-day run. World Ag Expo next year is scheduled for Feb. 10-12.

World Ag Expo is the world’s largest agricultural exposition with 2.6 million square feet of exhibit space, more than 1,600 exhibitors and more than 100,000 attendees annually. The official magazine is distributed to thousands of farmers and ranchers across the United States prior to the opening of the expo in February in Tulare.

Western Farm Press longtime editor Harry Cline will work with the World Ag Expo staff to develop information about the event in the magazine, show guide and on Penton agricultural publication Web sites.
