There's a great example in the report that I'll circulate through the clerk, which shows a vision of a technology-using machine. The developer is a company called Blue River. It's now owned by John Deere. It's a pesticide sprayer, and what it does, especially in the high-value crops, like lettuce—that's the crop that you'll see in the photographs—is to apply herbicides or fungicides or insecticides. As it's going down the field, it identifies the lettuce plants, and then, if it's putting on a herbicide, it identifies the weeds. It puts the herbicide on the weeds, and only the weeds, where it's needed. That's an example of precision farming.
Another example of precision farming—and again they talk about it in the report—is that right now we are able to map fields down into areas that are smaller and smaller and smaller, but as we move out, we're actually going to be getting to plant by plant by plant. Today when farmers here in Ontario are applying nitrogen fertilizer to their corn, there is a camera on the boom of the sprayer that measures the greenness of the plant. If it's greener, it needs less nitrogen; if it's a bit off the green, it needs more nitrogen. It's taking those measurements five times a second, and it's doing that across 60 feet. For 60 feet, five times a second, with the tractor travelling about five miles an hour, you can figure out that it's probably covering a couple hundred plants. In the future it will be one plant.
That's what the future is bringing us. It's bringing us agriculture in certain crops where precision agriculture is applying either the fertilizer or the pesticide or the other crop inputs on a plant-by-plant basis. That's what I'll call the extreme example of precision agriculture.
