Frost. The only good time for this word to be thrown around is at the end of harvest; when the growing season is all but over, our time in the field is winding down, and we look ahead to the coming winter with contentment. When it comes in the middle of May, and when it hits as hard as it did last week, it is far from welcome.
We were on our last day of seeding last Thursday, and we were excited for the end. It isn’t often that we get a run like we did this year. It rained right at the start of seeding, and then it stayed dry right through to the end. We never stopped once, despite numerous forecasts for rain throughout our planting season. The incorrect forecasts were unfortunate, as we pushed hard through all the way through, continually expecting what seemed to be an inevitable rain delay. The result? We were exhausted, mentally and physically, and seriously needed a break. It was time for the end.
My excitement Thursday morning was sharply dampened by the extreme cold. Forecasts had initially been calling for a low of -2 Celsius, which wouldn’t have been a problem at all. At this time of the year, crops are tough, and mild freezing temperatures are rarely a problem. But, later on Wednesday afternoon, the low was suddenly changed to -4. Thursday morning, I realized it was much worse: it had dropped to a low of -7 C. That is a frigid temperature for May.
At that point, I had no idea what the damage might be. All we could do was go out and finish seeding and hope for the best.
On Monday, the severity of the damage was apparent. The winter wheat had been hit hard, with a number of browned-off leaves and severe damage in any low-lying areas. The early-seeded durum and lentils were injured as well, which is very rare – these crops are tough in the spring. The frost must be substantial to injure spring cereals and lentils.
It was the canola that I was most concerned about. Unlike cereal crops like wheat and durum, canola’s growing point comes out of the ground pretty much at emergence. If that growing point dies, the plant is dead. And canola is not a crop that tolerates extreme cold.
After an entire morning on my ATV, taking plant counts and carefully examining the plants, I knew there was only one thing we could do. We had to reseed.
There are few things more frustrating than seeding into perfect conditions, far enough into May to not really be concerned about frost, and establishing a near-perfect stand of canola, all to have to go back in 3 weeks later and do it all again. Now, we are seeding into dust, praying for a rain to get the crop out of the ground. It is not a fun experience.
One of the most challenging things about making the reseed decision is that it is rarely black and white. A frost will almost never completely wipe a field clean. In both of the fields we had to reseed, and in one that we decided not to, we really didn’t know what the right decision was. Sometimes, if conditions are absolutely perfect, you can get away with a very small number of surviving plants. We just don’t know.
The bottom line of all this is that we need rain and we need it pretty soon. Yes, there are always parts of the season where we get too much or not enough precipitation, and it truly is rare for everything to be perfect, but you still have to get that initial rainfall to get the crop out of the ground. Imagine planting your garden, or flowers, or anything like that and not being able to water it. You have to hope that the rain will come.
Farming is unpredictable, and despite all our technological and genetic advancements, Mother Nature still holds all the cards. All we can do is the best job possible out in the field and hope the weather is favourable.
