Right time, right place: ISA to host fertilizer event

August 10, 2023 | Kriss Nelson

Are you getting the biggest bang for your buck when it comes to fertilizer? Could your farm benefit from varied placements and sources? The Iowa Soybean Association (ISA) will provide insights on these topics and more at an event later this month.

Optimizing Fertilizer Investments will be held Aug. 22 from 9:30 a.m. – 3:30 p.m. at the Iowa State University Alumni Center, 429 Alumni Lane in Ames.

The event centers on educating farmers and agronomists on better managing their fertilizer investments, which can dramatically impact ROI.

“There will be tremendous opportunities to learn about fertilizer with world-renowned experts,” says Scott Nelson, ISA research agronomist.

Topics range from building a soil fertility program to better managing nitrogen on your farming operation.

Breakout sessions and speakers

Crop management practices and water quality

Participants will about ISA’s water quality sampling and which practices are associated with improving water quality from ISA Water Lab Service Manager Tony Seeman

“Tony will give a snapshot of the nutrients we are losing from our soil factories that affect our water quality and how those fertilizer inputs could essentially be investment,” says Nelson.

Improving nitrogen management

Nelson will review how nitrogen form and placement affect profitability, how nitrogen responds across landscape positions and prospects for variable rate nitrogen.

Building the foundation for your soil fertility program

Antonio Mallarino, professor of agronomy and nutrient management research and extension specialist at Iowa State University, will discuss new phosphorus and potassium recommendations, cation exchange ratios, and what they mean for soil fertility and nutrient stratification in no-till production.

Fine-tuning the foundation of your nutrient management program

Dan Kaiser, associate professor for the University of Minnesota’s soil, water and climate department, will present findings on fertilizer application timing, emphasizing phosphorus and potassium.

Nitrification inhibitors, starter fertilizers, and biological corn nitrogen fixation products will also be discussed.
