PRAIRIE CITY, Iowa (Sept. 7, 2022) — Will and Cassie Cannon, of Cannon Family Farm, will host a Practical Farmers of Iowa field day exploring their findings from a range of cover crop on-farm research trials on Wednesday, Sept. 14, from noon to 2:30 p.m., near Prairie City (8718 W 109th St. South).

The event – “On-Farm Cover Crop Research Trials” – is free to attend and will start with lunch. Sign up online, or call Debra Boekholder at (515) 232-5661. The field day is sponsored by Albert Lea Seed, Iowa Farmers Union, Marion County Bank and Sunderman Farm Management Co.

Will and Cassie farm 1,400 acres of strip-till corn and no-till soybeans and use cover crops on a large scale. They use precision technology to apply nutrients at variable rates depending on field needs, which mitigates over-application and excess nutrient runoff.

Curious about measuring the benefits of cover crops, Will is working with PFI’s Cooperators’ Program to conduct on-farm research. In one trial, he is using water sensors to determine soil-water availability in research plots with cover crops versus plots with no cover. He is also conducting a trial to test the feasibility of 15-inch row spacing for soybeans planted green.

At this field day, guests will learn about Will’s cover crop research and his typical cover crop practices and equipment, including seeding and fertilizer equipment. Other topics the Cannons will discuss include intercropped cereal rye, reducing fertilizer inputs and small grains.
