4R Plus Field Day to Improve Profitability, Stewardship
Iowa Ag Connection - 07/11/2018

The Iowa Soybean Association (ISA) is hosting a 4R Plus field day that could help farmers improve their profitability, yields and have a positive impact on the environment.

The field day will be held July 31, from 9:30 a.m. to 2:45 p.m. at the Iowa State University (ISU) Extension and Outreach Field Extension Education Laboratory (FEEL) Farm, 1928 240th St, Boone. Farmers, agronomists and other stakeholders will have the opportunity to hear from experts who will present ways to use the 4Rs of nutrient management -- applying the right source, at the right rate, at the right time and in the right place.

The "plus" part of the program addresses how conservation practices coupled with good nutrient management can help farmers further improve their soil health and water quality. The goal is to achieve maximum profitability, yields and environmental stewardship.

"This is a very important field day for Iowa farmers, as it will address the latest advances in nutrient management and soil and water conservation," said Scott Nelson, ISA On-Farm Network director. "Farmers will leave this event with lots of ideas on how to improve profitability on their farms as well as protect soil and water."

The event is free, with lunch provided. Attendees participating the whole day can receive six continuing education credits (CEUs) toward their certified crop adviser (CCA) certification.

The field day will feature six speakers -- two ISU scientists, two ISA experts and two farmers -- who will share their research and experiences:

- Scott Nelson, ISA On-Farm Network director: 4Rs of nitrogen management.

- Antonio Mallarino, ISU professor of soil fertility and nutrient management: 4Rs of phosphorous and potassium research.

- Steve Killpack, a farmer from Neola: Insights into the profit-improving practice of variable rate nitrogen.

- Rick Cruse, ISU agronomy professor and director of the Iowa Water Center: Practices that can help reduce soil erosion from Iowa fields.

- Keegan Kult, an ISA environmental scientist: Edge-of-field practices that can help prevent nutrient loss.

- Dean Sponheim, a farmer from Nora Springs: Twenty years of struggles and eventual solutions to implementing conservation practices.

"I'm going to try and save other farmers a lot of headaches and let people know about the practices that will work in multiple areas of the state," Sponheim said. "What we're doing dovetails into the 4Rs and applies to all of them. There are things farmers have been doing that work for conservation and economic reasons."

This event is sponsored in part by The Fertilizer Institute, Mosaic Fertilizer, the Iowa Agriculture Water Alliance, 4R Plus and the Iowa Soybean Association. Space is limited to the first 150 registrants. To sign up, email Sue Heath:
