PTI Farm Agronomy Tour
/
Partners & Friends,
Last week I went to the Precision Technology Institute in Pontiac for their summer agronomy tour. There are a lot of very interesting things going on there. Here are some of my bullet-point takeaways:
Tile spacing: Tile is most efficient and cost-effective on 40-foot centers, with 20-foot centers in problem areas, across most soil types.
Soybean apical/meristem damage: If soybeans experience intentional apical/meristem damage when they are very young, there can be significant yield increases.
Drone technology: Drone technology continues to improve every year, with larger tank and weight capacities, longer battery life, and more self-guiding technology. Drones appear to be best suited for smaller fields or hard-to-access areas where a ground rig is difficult to use.
Corn genetics: Some of the highest-yielding corn varieties on the farm have been full-season DK 6835 and Pioneer 1742.
Symphony/Vision spray technology: This technology has the potential to drastically reduce chemical costs in post-emergence applications. John Deere currently charges farmers $5/acre for acres that are not sprayed, taking away some of that potential benefit.
Magrow Tech: Magnets are placed in the spray delivery lines and are reported to reduce drift by 90%, reduce chemical rates by 20%, and help with hard-water issues.
Phosphorus fertilizer: Phosphorus moves only about 1/8 inch per year in the soil. Putting fertilizer where the plant roots are located can dramatically increase efficiency and reduce the amount of fertilizer needed.
Strip-tillage: Strip-tillage allows for a 25–50% reduction in fertilizer rates and has consistently shown about a $30/acre advantage.
Arrow seed tubes: Arrow seed tubes can provide up to 80% tip-down placement, which can help improve early corn emergence. Availability is expected in 2028.
CIH closing system/FurrowForce: The CIH closing system coupled with FurrowForce appears to provide more consistent corn and soybean emergence.
AgZen: AgZen technology helps apply fungicides as low on the plant as possible. Fungicides primarily move upward through the plant, so lower application can be more beneficial.
Carbon Builder: Carbon Builder is offering five-year contracts for carbon credits. Talc is applied at a cost of about $13/acre, with a possible $50/ton payback for yields of 1–2 tons/acre.
Razdicle soil sampling: Razdicle offers consistent and quick-turnaround soil sampling.

We put in some main tile lines this week, mowed roadsides and waterways, and got the cornhead out to prepare for harvest. With all the rain and heat, it’s hard to keep up with the yards! Landowners, I have the base-acre allocation updates. If you are interested, let me know.
The USDA crop report comes out today, and the Pro Farmer Crop Tour is next week. The Farm Bill was delayed in D.C. last week. We are still waiting on IRS guidance for 45Z. Commodity traders are anticipating a big corn and soybean crop.
Off to the State Fair this week—we’ve been preparing for this year’s fair for the last several years! School is starting this week in some places. The Cubs still have a chance at a wild-card spot. The Bushnell Fall Festival is next week. Last weekend, the Uncommon Men's Conference in Quincy was very edifying, and I would recommend attending in future years.
Fall Prices:
Corn — $4.45
Soybeans — $11.48
