Frost hits a huge swath of the Prairies

As the season changes to fall, the leaves find new colours, football starts, and crops attempt to finish prior to the first hard frost.

In a very quick weather change over the last four days, Tuesday morning brought extremely cold temperatures to large parts of the Prairies, from Manitoba, through Saskatchewan, and into Alberta. Night time temps fell to -10 in some areas, and for hours at a time (see below).

Don’t Miss: When evaluating frost damage in canola, patience is key

Depending on where you are farm, the level of damage is varied. In Manitoba, there is concern regarding the soybeans and corn while in parts of Northern Saskatchewan the main concern is later seeded canola.

Depending on the stage of the crop when frost hits, it can have very little impact, all the way through to having a significant impact both on yield and quality. A crop that ends up dying before it has reached physiological maturity can mean lost yield and higher drying costs, plus oilseeds can end up with locked-in green seed (chlorophyll that won’t clear the seed).
