I think there are two components there. One of the challenges we face, given the wide range of spatial variability associated with soil carbon, with asking a farmer to do this without providing a lot of important context to them is just knowing how to collect the sample properly, because collecting a soil sample for analysis.... If you over-compact it, for example, or you get too loose of a sample, that's going to influence your results. As well, there's going to be a big implication from where in the field you collect the sample, so a farmer might inadvertently overestimate the amount of carbon they have depending on where they collect that sample.
I think a combination of a more controlled or government-organized data sampling strategy would be important, but it could be complemented with some of those other techniques. For example, as we build that spectroscopic database that I was referring to earlier, there may be more opportunities for producers to collect more of those samples themselves, or in partnership with the agronomist they might hire to help with their work as well.
