Agronomist: Some Soybean Frost Kill In Midwestern Ontario


Soybean plants just hooking through the surface appear to have taken the brunt of the frost damage from this past weekend.

That’s according to Cargill agronomist Jeff Jacques.

He says the Midwestern Ontario soybean fields he’s checked are showing that plants fully out of the ground are in better shape than those just hooking through.

Jacques expects those just hooking through – the ones that are brown now – will dry out and break off over the next few days of sunshine.

He says those likely won’t produce a plant.

However, he says it’s important for growers to remember it’s not so much how many plants you have as how evenly they’re spread over the field.

Jacques says soybean plants are elastic – meaning they will compensate and branch out more to fill in any gaps – as long as those gaps aren’t too big.

Both Jacques and OMAF’s Greg Stewart figure the corn crop dodged any significant frost damage.

Stewart says because most of the corn plant’s growing points are still below ground he’s not expecting any real mitigating damage to the crop.


Cargill agronomist Jeff Jacques says he’s seeing areas where there’s no green leaf tissue on as many as 25 per cent of the plants.


Jacques says while plants that are fully out of the ground seem to be okay, the ones just right at the surface are looking pretty brown right now.


Jacques points out it’s not so much the number of plants you have left as how evenly they’re spread out over the field.
