2026 Trials Update

DEEP PHOSPHORUS PLACEMENT

This trial began in the spring of 2023 with 4 treatments:

• Control – Regular seeding
• Worked only (5” depth)
• Deep application (5” depth) of 190lbs of MAP (100lbs P2O5)
• Broadcast application of 190lbs of MAP (100lbs P2O5)

Each year the crop is seeded perpendicular to the initial treatment direction. We use the same seed and fertilizer rates as on all other acres across the farm. The results to date show the following:

• Canola responds to deep phosphorus whereas wheat appears less responsive.
• Broadcast of phosphorus can be beneficial, but the effects tend to appear in later years.

CANOLA SEEDING RATE

In this trial, the same drill and fertilizer rates are used, only the seeding rates change. This year we saw the following:

• The mid seeding rate produced the highest yield. Typically, in drier years the lower plant stands yield better, while in wet years the higher plant stands perform better.
• As seen every year, lower plant stands result in longer maturity.

WHEAT - TRIMAX SPLIT NITROGEN

Using the TriMax configuration with three airstreams, we tested placing some nitrogen closer to the seed in the side band with the starter fertilizer.

• We did not see a significant benefit to splitting the nitrogen this year.

LENTILS TRIALS

The Bourgault Agronomy has added a second location for replicated, field scale trials near Odessa, SK. We trialed phosphorus placement and seeding rates.

• This year we didn’t see any significant differences between phosphorus treatments, nor did we see a significant benefit to applying phosphorus in general.
• Trials will continue next year and plant counts will also be taken.
