Your Advanced Yield Systems Weekly Spotlight: 

Erin Stackhouse

Some of you may remember my article back in August about a field that had multiple fungicide applications throughout the growing season.  At that time, the imagery on Climate started showing a difference 8 days after application, which is something we usually don’t see that soon. Let’s dive into these results- because they are very interesting!


2 Applications Timings : V5 & VT

V5 Applied:

  • Pink:  6/8/21 with Trivapro + Max-IN Zinc + Voyagro

Ground Tassel Applied: 7/12/2021

  • Green : Miravis Neo + Max-IN Boron + Max-IN K + Voyagro + Masterlock
  • Maroon: Miravis Neo + Max-IN Boron + Masterlock
  • Blue :  Trivapro + Max-IN Boron + Max-IN K + Voyagro + Masterlock

Climate Imagery Shown Above :
8 days after application (top left),
23 days after application (top right),
Last day of Climate imagery on Sept 6th (bottom)

Average Yields & Map Below:

  • 229 bushels = No fungicide applied 
  • 244.6 bushes = V5 application
  • 256 bushels = VT application

Talk to your local agronomist about locking in your fungicide & micros for 2022!

Harvest is still underway, but we are starting to see a light at the end of the tunnel. As everyone is wrapping up harvest the fertilizer is still going on and we are starting to think about starting anhydrous. The soil temp is right around 60 degrees and falling fast with the cold nights. For fall applied anhydrous you want the soil to be around 50 degrees.

With anhydrous hopefully getting underway in the next few days, it is important to remember to put N-Serve, a nitrogen stabilizer, on with the anhydrous to prevent leaching and denitrification from happening. The N-Serve slows down the bacteria that converts the ammonium to nitrate, keeping it in the stable form longer.


If you have any questions, please talk to your local Ag Partners agronomist and have a safe end to the season!

“Beans ran about 54. Rocky spots hurt the average pretty bad. All things considered, very happy for the year.”

“(Farm A) is setting a record.”

“Looks like low 60’s with 12.5% H20.”

“(Farm B) did 238 and (Farm C) was doing 239 when I hopped out of the combine!”

“(Farm D) was bad. (Farm E) was pretty good.”

“Need to soil sample (Farm F), I’m taking that over and planting alfalfa.”

“231 bu / ac on (Farm G).”

“(Farm H) is not real good.”

“Yup they did 62”

“81 across the scale on mine.”

“Mid 70s on (Farm J)”

“Done with beans. 55 average.”

2021 continues to be a year like no other- long stretches of great weather to get field work done. Just like the rest of our 2021 growing season, fall harvest has been a lot of nice steady days with very few weather interruptions. As I write this (late morning Wednesday), locally we received a light little thunderstorm that brought minimal rain. The forecast early this morning was saying that we should receive about an inch of rain today, and just like all summer long as soon as the clouds roll, in the weatherman lowers the rainfall amount drastically. By the time you read this we will know the outcome of this little weather system moving through.


We are now in the tail end of harvest- a lot of the fertilizer in our area has been applied and there is a very good start on fall tillage. As temps drop after this rain system goes through, we should see those white tanks rolling around the countryside. Its hard to imagine that it is only the 20th of October. Just like all season long it feels like we are two weeks ahead of schedule. We don’t often get years like this and I know that there is still work to be done, but I think we should all take a minute to be thankful for a great crop and wonderful weather to complete the harvest.

A few things that have stood out to me this fall.

  • Fungicide applications are making a big difference on both standability and final yield.
  • Nitrogen hasn’t seemed to be a limiting factor.
  • High fertility paid big this year.
  • Later maturity corn yielded better.
  • Early soybeans are keeping up with late ones well.

Biggest yield drags:

  • Rain fall totals and timing in both corn and soybeans.
  • Final population in corn.

Harvest is underway! This is one of my favorite times of year to be involved in Agriculture for many reasons such as: learning what worked, what didn’t work, how management decisions relate to production, and ultimately riding in the combine with great people.

I have noticed a large difference in yield on farms that sprayed fungicide at R1 versus no fungicide application.


I have been receiving multiple reports from customers of responses ranging from 18bu – 50bu yield differences on corn alone! It is our understanding that with the mid-late July and early August dry weather (post R1 application), that the untreated plants had more of a “die down effect” rather then a natural progression to black layer.  This ultimately stressed the plant during kernel development and grain fill, resulting in drastic yield differences. Below is a picture of a farm that was sprayed north and south and as you can see in the picture where the helicopter left the check strip circled in blue.

With being blessed with good weather during harvest, it is always a good idea to slow down and learn about the results you’re seeing and what is driving those. It is great to ask questions to your Ag Partners team, to help you understand the data and make note on what worked, what didn’t work, and how to improve for future years! Have a safe rest of harvest everyone and thank you for another great season!

As harvest slowly draws near the end in areas of Western Wisconsin, many of our farmers are in much higher spirits than when they first fired up those combines. Early yield estimates that humbled many of us through this droughty season have been left in the dust. As of Aug 1st, the USDA’s crop production report estimated average Wisconsin corn yields at 167 bu/acre and soybeans at 49 bu/acre. Corn seems to be holding its own with multiple areas averaging from 180 to over 200 bu/acre, and beans running closer to 60 bushel which is nothing to be upset about.

With that said, following close behind our harvesters are our hard-working soil sampling crews. Soil sampling is one of the most economical tools available to the farmer and for good reason.

Fall Soil Sample Benefits:

  • Get a head start on your fertility program. Know what nutrients you need to build right away and where they should be allocated across your operation.
  • Control your soil acidity with fall lime if need be. Not knowing where your pH sits can spell out for huge losses to your crop.
  • Pre-planning can save you time and money!
  • Spread out your workload. Spring can be hectic so sampling now can be a real weight off your shoulders.

A good reminder even for those not interested in grid sampling- composite samples can be just as beneficial for your operation (especially if it has been 3-4 years since a field was last sampled). Be sure to stay in touch with your agronomist for the best management options!
