The 4R Nutrient Stewardship provides a framework to achieve cropping system goals, including increased production, increased farmer profitability, enhanced environmental protection and improved sustainability.

To help achieve these goals, the 4R concept incorporates the right fertilizer source at the right rate, right time and right place.

Presentations covering those goals will be the focus of an upcoming 4R Stewardship Day on Monday, Aug. 29 at Kirkwood Community College in Cedar Rapids.

Scott Nelson, Iowa Soybean Association (ISA) senior field services program manager says the annual event provides the latest advances to improve farmers’ fertilizer management.

“Any producer interested in improving their nutrient management should attend,” says Nelson. “4R stewardship is essential for a farmer’s profitability and to help them meet their nutrient stewardship goals."

The four breakout sessions will include:

  • Fertilizer banding by Jake Vossenkemper of Liqui-Grow and Sean Arthur, Environmental Tillage Systems. “In this session, attendees will learn the benefits and pitfalls of banding fertilizers,” says Nelson. “In some cases, they can save on their fertility bills and improve nutrient management with this system.
  • Regenerative Nutrient Sources by eastern Iowa farmer Mike Bretz and Evan Brehm, conservation agronomist for ISA and Linn Co-op
  • Managing Manure Nutrients by Brent Pacha with Sinclair Tractor featuring the program Manure Sense.
  • The Iowa Nitrogen Initiative by Mike Castellano, a soil science professor at Iowa State University. “Mike is leading a new effort with ISU to improve nitrogen rate recommendations,” says Nelson. “He will talk about his program, which involves producer involvement and recent results.”

This collaborative event is made possible by ISA and 4R Nutrient Stewardship and is sponsored by the Agriculture’s Clean Water Alliance, The Mosaic Company and Environmental Tillage Systems.
