Challenging harvest conditions

Ice Canola

For most growers across the prairies, harvest this year has been challenging. Considerable rainfall in August and September delayed harvest throughout the Prairie Provinces, and early snowfall impacted many parts of Alberta and Saskatchewan. Now, growers are faced with uncertainty and have tough decisions to make. When the weather improves, what crop do I take off first? What will happen to the canola left standing in the field? What happens to swathed canola that was hit by snow? What are my options?

Below are some valuable resources to help you when making these difficult decisions:

The Alberta Canola Producers Commission have outlined some great tips for harvesting canola that was immature, ready to swath or left standing in areas where it has snowed. View the article here.

For grain being harvested now, Manitoba Agriculture has some useful tips on how to combine and store canola that has been tested as tough or high in moisture. For more information, click here.
Your nitrogen needs protecting, even in cold temperatures

Protect Your Nitrogen

When the winters are long and soil is cold, you may think your fall-applied nitrogen is going to stay put. Not necessarily.

Maximum nitrogen uptake occurs by late flowering to early ripening in both canola and wheat, long after the ground has thawed in spring. By not protecting your nitrogen, you could be leaving it susceptible to leaching (washing away) or denitrification (gassing off) once the temperature increases and snow melts in spring.

When you protect your nitrogen with a nitrogen stabilizer, it stays put in the root zone and ultimately contributes to yield gains as high as 8% in canola. If you’re growing Nexera™ canola with a nitrogen stabilizer, the premium earned plus yield increase of a nitrogen stabilizer could earn you $43,000 more* for every 500 acres on your farm!

*Nexera canola protected with a Nitrogen Stabilizer returns an average of $86/ac more on every 500 acres compared to commodity canola.
 
What are growers saying about nitrogen stabilizers?

Wheat Field

We talked to growers who used nitrogen stabilizers on their crops in 2016. Here’s what they had to say:

“I did half a field with [N-Serve] and half without, and I’ve seen enough [on the spring wheat] that we will probably never put another tank of anhydrous on without it.” Jason F., Manitoba

“I got very near to an 8 bushel per acre increase.” Martin P., Saskatchewan

“At a 4 ½ bushel increase, it tripled its investment. If it does that again year after year, it’s a cost I’m willing to spend.” Joel H., Saskatchewan
Here’s where you’ve pegged your nitrogen loss

Canola Field

We asked our AgWise audience in the September 26 issue what you estimate your average nitrogen loss to be. We received over 140 responses. Here’s what you told us:

52% estimate average nitrogen loss at 0-10%
44% estimate average nitrogen loss is 10-30%
4% estimate average nitrogen loss is greater than 30%

Did you know? At a soil temperature of 15 degrees C, it takes only 5 days of saturation to lose 10% of your applied nitrogen.
