There are some really exciting discoveries on the horizon. Recently, the Government of Saskatchewan invested $300,000 with the Global Institute for Food Security in nitrogen-efficient wheat. This is a wheat variety that would be able to produce similar or greater yields while using less nitrogen. That's not a focus on demonizing nitrogen; it's saying that this is a way to tailor those plans together with the variety to hit the optimal levels.
Even regular varieties we have now, they all go through trials where you look to see what the optimal level of fertilizer is. Growing up on a farm, I know that my dad never wanted to put an ounce of fertilizer on the ground that he didn't have to. They're looking to minimize inputs in every space, whether it's seed, water, fertilizer or pesticides. You're always trying to grow the most on the least with the least.
I think innovations like nitrogen-efficient wheat and other varieties that can do similar things will be very beneficial to agriculture in the future.
