UW Agronomy/Soils Field Day Set For July 9

This year”s Agronomy/Soils Field Day will feature a “tent show” discussion of Bt corn, along with four tours that highlight current crops and soils research. The event is scheduled for Wednesday July 9 at the University of Wisconsin-Madison”s Arlington Agricultural Research Station.

At the 1 p.m. tent meeting, UW-Madison experts will discuss field observations on insect pest problems in Bt corn, what to expect next after Bt corn for corn borer and rootworm, and why we need non-Bt refuges to slow the development of insect resistance to genetically modified corn. During a luncheon talk at 12:15 p.m., agricultural economist Bruce Jones will review cropping decisions and the 2002 Farm Bill.

Specialists from the College of Agricultural and Life Sciences and UW Cooperative Extension Service will staff four field tours departing from the Public Events Facility at 8:30 a.m., 10 a.m. and 1 p.m.

The forages tour will look at corn production in a kura clover living mulch, switchgrass for bioenergy, wheel traffic effects on alfalfa, and new grass varieties.

The crops tour (8:30 a.m. and 10 a.m. only) will feature specialty soybeans, raising awareness of Wisconsin soybean grain composition. canola for Wisconsin, and managing corn silage for NDFD.

The weed and disease management tour (8:30 a.m. and 10 a.m. only) will review the importance of timing sprayings, new real-time weed decision tools for Wisconsin, weed populations after 5 years in glyphosate-resistance corn and soybean, and what”s causing poor ear development in corn.

The managing soils, nutrients and poplars tour will look at short-rotation intensive culture of hybrid poplar, measuring manure nitrogen availability using labeled nitrogen, tillage and potassium management in first-year corn after alfalfa, and manure timing and placement effects on phosphorus losses in runoff.

Lunch and refreshments will be available. If it rains the presentations will be made inside the events facility.

The Arlington Agricultural Research Station is about five miles south of Arlington and 15 miles north of Madison on U.S. Highway 51 in Columbia County. Exit Interstate 90-94 at Wis. Highway 60 or exit U.S. Highway 51 at Badger Road and follow the signs. The College of Agricultural and Life Sciences and UW Cooperative Extension co-sponsor Agronomy Field Day.
