Yes. I'll start with the testimony.
I have many examples from the 34 farms that are part of the 100,000 acres in the United States. Closer to us, I've been able to meet with at least two Quebec growers who are into what we call in French “les grandes cultures”. I'm sorry; I am not sure exactly how to translate that, but it's corn, peas and soy.
It took these guys quite a while because they were self-reflecting about all this. In the end, they have 10% to 15% more output, and they have reduced their costs because they no longer use chemical fertilizers. They have not yet arrived at a fully organic product, as Mr. Lévêque just described, but they tend to be closer to this because these practices reduce energy.
You go less often into your fields with your tractor, so you generate less carbon, and you leave the soil to restore itself because the soil has everything it needs to do so. You never leave it bare. By adding cover crops, you capture more carbon, so you don't need the input.
In the end, they're winning on all fronts. They're winning on higher yields and lower costs. However, to characterize it with a real number depends on what you grow and where you are. That's why a testing measurement is required. Whatever we've found works great in Ohio we couldn't apply in Lac Saint-Jean, and whatever works well in Ohio doesn't work in Kansas. Unfortunately I do not have the silver bullet to solve everything today, but we know that the principles work. They just have to be adapted to each region and each type of plant you're growing.
