REGISTRATION FOR THE FINAL EVENTS IS NOW CLOSED. SEE YOU NEXT YEAR!

Two events are held at the end of the Great Ontario Yield Tour. These events are held to bring farmers up to speed on the tour findings and to learn more about how to better their yields by providing demos on new technology, farm management practices, and agronomy.

Certified Crop Advisors can now earn Nutrient Management and Crop Management CEU Credits when attending either event!

Guest Speaker - Shaun Casteel
Associate Professor of Agronomy, Soybean Specialist
West Lafayette, IN

Main Presentation Topic

Setting and Expanding on Foundations to Maximize Soybean Yield.
Intensive management practices often include high rate and/or frequent applications of fertilizers and pest protection products that counter environmental awareness and long-term sustainability. Shaun Casteel has explored the opportunities for synergy in soybean management by adding a product, practice, or system while determining economic viability. The synergistic opportunities with sulfur fertility and cultural practices (e.g., planting date, field condition, cover crop, foliar protection) has been a major focus in his research. His goal is to underpin management decisions with the evidence found in the observed development and growth of soybeans in response to environment and management interactions. Foundational management must be set before exploring the “next and greatest” practice. Casteel will discuss these interactions and address your questions.

Educational Demo Presentation Topic

Is Sulfur the Solution for Soybeans?
Reductions in atmospheric deposition of sulfur (S) coupled with yield increases of soybean have led to more responsive situations to S applications. Sulfur is needed as a co-factor for root-nodule formation; thus, a limited S supply can restrict biological nitrogen (N) fixation of soybeans. This combination of a low supply of S and N (via poor nodulation) can restrict yield (from 5 to 20 bu/ac) and the quality of soybean grain (i.e., protein). Shaun Casteel categorizes soybean responsiveness to S applications into two areas. The first category is true S deficiency based on the soil supply and lack of deposition. The second category is where the soybeans are situationally deficit in S based on the combinations of field characteristics and management (e.g., planting date, cover crop, foliar protection synergies). Casteel will explain when and the why (and the why not) we see soybean response to sulfur.

• 8:00am - 8:30am Registration
  • All pre-registered attendees will be pre-assigned to a group.
    An email will be sent the day before the event advising attendees which group they are in.
    All attendees must check-in with their group leader outside the Maizex Dome.
    NON-REGISTERED ATTENDEES WILL NOT BE ABLE TO ATTEND THE EVENT.
• 8:45am: Demo Presentation Rotation
  Attendees will travel in groups to each of the following presentations.
  • Hensall Coop - Rising Demand, Shrinking supply: Eastern Canada’s Corn Market Outlook
    Will there be enough Corn?  What is moving the market and what it means for your farm?
  • Maizex - Getting the Most from Your Hybrids using Flex and Tissue Sampling
    In this demo we will be discussing where our hybrids flex and how we can use in season testing of soil, tissue and use weather patterns to better understand how to manage each hybrid. Can we help influence higher yields in corn by managing right off the start and monitor development and nutrient levels season long.
  • Taurus Ag - Fertility vs Fertilizer - Where agronomy meets logistics and economics
    Dive into the world of fertility vs fertilizer - learn what's new in the world of modern agronomic inputs focused on seed fertility, plant fertility and soil fertility. It's time to rethink fertility inputs - modern agriculture is shaped around use efficiencies, placing fertility where and when it's needed to grow the healthiest crop possible. Discover the newest strategies to enhance crop yield and plant health. Don’t miss this opportunity to gain valuable insights and practical tips for optimizing modern farming operations.
  • Terralynx - What’s Next: AI, Automation & Ag Data in 2025
    In this session, we will share what’s coming in 2025 and beyond: how artificial intelligence is helping us generate instant, field-ready insights from multispectral and LiDAR data; how automation is cutting time from flight to decision; and how new tools integrate directly with tractors, maps, and management software.

Guest Speaker - Dr. Peter Sikkema
Professor Field Crop Weed Management
University of Guelph, Ridgetown, ON

Main Presentation Topic

Two of Ontario's biggest weed management challenges in 2025: Multiple herbicide-resistant Canada fleabane and waterhemp
Glyphosate-resistant Canada fleabane was confirmed in Ontario from seed collected in 2010 in Essex County adjacent to the Michigan border. It is now present across the southern crop producing area of Ontario from the US border to the Quebec border. GR Canada fleabane interference in corn and soybean caused an average 54 and 65% yield loss, respectively. Canada fleabane control options in corn and soybean (IP, E3, and XtendFlex) will be presented.

Glyphosate-resistant waterhemp was confirmed in Ontario from seed collected in 2014 in Lambton County adjacent to the Michigan border. Waterhemp has evolved resistance to the Group 2, 5, 9, 14, and 27 herbicides in Ontario and is now present in across the southern crop producing area of Ontario from the US border to the Quebec border. GR waterhemp interference in corn and soybean caused an average 19 and 43% yield loss, respectively. Waterhemp control options in corn and soybean (IP, E3, and XtendFlex) will be presented.

A brief comparison of E3 and Xtend soybean will be presented.

Educational Demo Presentation Topic - Holly Byker/Dr. Peter Sikkema

Weed Wisdom and Herbicide Hacks in Soybeans
The demo will provide an opportunity for hands on identification tips and tricks of common but difficult to distinguish species, at various stages of development. It will also look at commonly used herbicides, and show which herbicides are amongst the top choices for controlling these weeds in crop.
