Many years of this….A typical field stop in canola to assess crop stage, weeds, and flea beetle feeding damage.

Same quarter split into two 80 acre fields farmed independently until combined this year. Pic 1 area is rich in nutrient supply only requires 60-20-0-0 for 90 bu wheat. Pic 2 tanked nutrient supply requires 115-45-33-11 for 90 bu wheat. Mistakenly applies 60-20-0-0.

WesternAg optimizations aren’t just about N. Very high yield potential canola here. These fields had high P supply (therefore not deficient) but very deficient on S. Optimized/applied rates on the pics.

The last several years have been off and on drought. Coming off one or multiple years of high N applied and low N removal is the background that leads to elevated N. This oat field is the only zero N rec for 2025. No N applied here.

We presented our rec of 125 lbs N for canola to this client. He asked to revise it trimming the rate to his budget and still giving a shot at a decent crop. 85 lbs applied.

Client texted me from the sprayer about this field. We recommended application of 30lbs N. 60 lbs applied.

This field has been in bloom since June 26th. Fungicide app July 4th. Sprayer tracks now quite overgrown.

Applied N requirements for high yielding spring wheat can easily be 150 lbs or higher. I was out touring some fields yesterday where we applied lower rates due to elevated N soil supply. This field had 75 lbs N applied so half of required N will be supplied by the soil itself.

11 years ago I made an applied N rec of 0 on this field due to high N supply from the @westernag test result. Client texted from combine to tell me that the wheat was running over 90 bu. At the time was the highest yield I had seen. Applied 50 lbs N this year looking just as good

The 2025 wheat crop that has been so seriously affected by drought still has some cards to play. One card is a late tiller response to recent rains that may take advantage of the open canopy and proliferate if conditions stay favourable.
