Cover Crop Field Day to Be Held Near Grinnell Sept. 14
Iowa Ag Connection - 09/13/2021

A cover crop field day will be held Sept. 14 from noon to 2 p.m. at Roger Van Donselaar's farm near Grinnell. The event is free, open to the whole family and includes a complimentary meal.

Cover crops continue to grow in popularity in Iowa due to their many benefits, including reduced soil erosion, weed suppression potential, reduced nitrogen and phosphorus loads entering water bodies, and increased soil organic matter. Cover crops and no-tillage work together to help increase water infiltration and reduce erosion during heavy rain events.

The event is supported by Iowa Learning Farms, Iowa State University Extension and Outreach, and Poweshiek County Soil and Water Conservation District. The event aims to equip attendees with best management practices to maintain yields during the transition to a higher residue system of no-tillage and cover crops.

The workshop will begin with a panel discussion with host farmer Roger Van Donselaar and Poweshiek County farmer Mike Phillips. Van Donselaar has been using no-till on his corn and soybean farm for nearly 30 years and added cover crops to the system six years ago to help with reducing herbicide usage and control erosion.

Rebecca Vittetoe, field agronomist with Iowa State University Extension and Outreach, will provide cover crop species and seeding best management practices and share tips for those considering grazing cover crops. Liz Ripley, Iowa Learning Farms conservation and cover crop outreach specialist, will then share results from cover crop projects examining water quality implications and soil health indicators such as earthworms. Beth Brand, Poweshiek County Natural Resources Conversation Service district conservationist, will share county updates and program opportunities.

Roger Van Donselaar's Farm is located at 511 6th Ave. West, Grinnell. The shop and bin site are located on the north side of the road, just west of Grinnell Health Care Center.

The workshop is free and open to the whole family, but reservations are suggested to ensure adequate space and food. For reasonable accommodations and to RSVP, contact Liz Ripley at 515-294-5429 or
