Visitors to the Marshfield Agricultural Research Station’s summer field day can take a guided tour of the station”s soils. The morning soils program will feature a walk-in soil pit. As visitors explore the pit, UW Madison soils scientist Fred Madison and John Peters, director of the UW Soil and Forage Analysis Laboratory, will discuss the soil-forming factors that influence management of our soils. UW-Extension soil scientists Larry Bundy and Keith Kelling will talk about how management practices affect soil phosphorous, and the effects of soil pH and topdressed potassium on alfalfa.
During the afternoon agronomy program, Clark County crops and soils agent Ron Wiederholt will demonstrate a Super Conditioner for conditioning mowed hay. UW-Extension corn specialist Joe Lauer will discuss row spacing and corn yields, UW-Madison entomologist David Hogg will review options for controlling potato leafhopper, and UW-Madison plant pathologist Craig Grau will talk about diseases of soybeans.
The field day begins Wednesday, July 11 at 10 a.m. and concludes at 2:15 p.m. There is no program cost, and lunch will be available on the grounds for a nominal fee.
