You bring up a good point in terms of the difficulties and the effort that would go into it. I think you're right that maybe 10 or 20 years ago it would have been difficult. Now with technology and innovation, with the drones and X-rays, I think the ability for you to do it quickly is certainly much different from when you were going out there physically trying to test soil. I think you're right.
Can you explain to me a little bit more about the in situ soil monitoring? That's something I have not heard before.
