Prairie harvest progress sits at roughly 45%, against a five-year average of more than 80% for this point in the season, as persistent wet and cool weather keeps combines out of fields across Alberta, Saskatchewan and Manitoba.

Lyndsey Smith of RealAg Radio delivered the figures in an interview with RFD News on Wednesday's Market Day Report. Some farmers have returned to fields as conditions improve, she said, but the prolonged wet weather is now raising serious concerns about crop quality across all three Prairie provinces.

One farmer told RealAg Radio he started a wheat field at the end of August before rain forced him to stop — and he could not get back in for three weeks.

"That wheat crop stood mature, ready to be harvested for weeks in the rain," Smith said. "And that, of course, leads to the inevitable downgrading and poor quality, and even sprouting."

Wheat and cereals take the biggest hit

Not every crop is faring equally badly. Canola has shown some standability issues, and sprouting can also become a concern in the oilseed. Wheat and other cereal crops have taken a bigger hit from the wet conditions.

Malt barley meeting quality specifications could also become harder to find, according to Smith.

For wheat, a key worry is falling numbers — the measurement that indicates sprouting or enzyme activity in the grain. It matters well beyond the farm gate.

"That falling number impacts what you can do with the eventual flour that we will make," Smith said.

The delayed harvest and widespread quality problems will also make marketing harder through the winter. Blending lower-quality grain with better-quality grain becomes more difficult when a larger share of the overall crop carries quality issues.

"Farmers are going to have to be pretty sharp with the pencil on their marketing," Smith said.

Drying costs stack up

Wetter grain coming off the fields means grain dryers are running heavily, adding another expense for producers already facing downgraded crops.

Farmers are pushing back into fields whenever conditions allow, Smith said, but crop quality and handling costs will remain concerns even as progress picks up.

Compaction threatens next season

The slow pace carries risks beyond this crop. Wet field conditions could create longer-term problems heading into spring, because running equipment over saturated soils can cause compaction that affects future yields.

"The question as well is not just, can you get the crop off, but what does a field look like when you're done?" Smith said. "Because that's going to significantly impact next year as well."

If the slow harvest pace continues, farmers with a larger share of low-quality grain will face tougher blending and pricing decisions in the months ahead. Prairie growers should watch drying capacity, falling number results and field trafficability as the deciding factors for both this season's crop value and next year's yield potential.
