AMES, Iowa — On-farm research trials being led by Iowa State University will be discussed at a field day near Jefferson Sept. 11.
The event will take place on the James Andrew farm, which is six miles south of Highway 30 just west of the Highway 4 and 280th street intersection. The Andrews farm is the site of two 80-acre precision farming research trials. But research in dozens of Iowa fields in and near Greene and Boone counties also will be discussed.
Topics will include the benefits of doing on-farm research, nitrogen management practices that increase profits for farmers while decreasing environmental pollution, soybean yield reduction caused by high-pH soils, and remote sensing that can help crop producers make management decisions.
Speakers will be Alfred Blackmer, ISU agronomist, and Tracy Blackmer, Iowa Soybean Association. Presentations will begin at 1 p.m. and repeat at 4 p.m. Aerial photographs showing thousands of acres in the area will be available for viewing after the presentations.
The field day is sponsored by Iowa State University, Iowa Corn Promotion Board, Iowa Soybean Promotion Board, Iowa Soybean Association and West Central Cooperative.
