Integrated Crop Management

Weed Ecology Field Day is August 16, 2004

A field day focusing on the impacts of crop rotation on weed population dynamics will be held Monday, August 16, near Boone, Iowa. The event will be held at the site of a 21-acre experiment involving 3 crop rotations (corn - soybean; corn - soybean - small grain/red clover; corn - soybean - small grain/alfalfa - alfalfa). Information on why weeds respond differently to the rotation systems will be presented. Speakers include Matt Liebman, Bob Hartzler, and Andy Heggenstaller from the Iowa State University Department of Agronomy; weed management practitioners; and others. Refreshments will be served after the field day.

Date and time: Monday, August 16, 3:00-5:00 p.m.

Location: The field day will be held near the Agronomy and Agricultural and Biosystems Engineering Research Farm on U.S. Highway 30 west of Ames. Turn south off Hwy. 30 at the Iowa State University Research Farm, proceed one mile, and turn right. Proceed approximately 1/2 mile (across from Iowa State University FEEL facility) and turn right onto lane.

Who should attend: Farmers and agronomists interested in (1) how cropping systems influence weed populations and (2) how we can manipulate these systems to enhance weed management.
