Here are the details provided by organizers Bob Streit and Marv Mortensen:

This meeting is designed to provide the latest field crop production information to consultants and farmers. Speakers will share their 2018 recommendations and give an overview of the successes that they have seen in the last few growing production seasons. This will help prepare growers to remain profitable in the 2018 growing season. These experts have been able to trial products and select products that offer high ROIs and better plant health. 

Main focus of the conference:

  • Soil health
  • Plant health
  • Micronutrients 
  • Nitrogen management & Nutrient efficiency

You’ll be able to network with top growers, scientists, agronomists, and product specialists. You’ll receive practical information and will be able to get your questions answered by the experts. 

The top 10 reasons you won’t want to miss this meeting:

  1. Learn how we produced big yields in 2017 and learn how to apply this knowledge in 2018.
  2. Learn what newer products seem to produce the highest ROIs.
  3. Learn what steps and products can improve soil health and increase your Haney score.
  4. Learn how good soil health correlates to good plant health. 
  5. Learn how and when you should sample your fields for the Haney analysis.
  6. Learn how much it will cost and how long it might take to build the desired test levels for high yields.
  7. Learn about humates, what they do.
  8. Learn about N stabilizers to minimize N runoff and leaching.
  9. Learn the new cutting edge facts and the benefits of using silica fertilizers on plants. This information has never been shared before in Iowa.
