Primarily it's ranchers and farmers globally who want to get paid to add carbon to their soils by adopting more soil-friendly practices. This is a rapidly growing market as more companies are looking to offset their emissions. There's also a good deal of growers simply interested in learning about the climate impact of their practices, or soil researchers studying the carbon impact of various practices.

Current soil carbon measurement methods are very cost- and labor intensive, so our in-situ spectral probe will make these measurements much more accessible.

I would like one for home gardening. Soil carbon is one measure of soil health.

stick your finger in and see if it is black with humus!

You'd probably need an effective carbon economy and regulatory framework that would reward soil with good carbon sequestration.

But to your point, the masters human race would rather destroy themselves that do things like that.

No. Healthy soil means high carbon content (mycelium, microbes etc).

"Dead soil" that has been tilled too much will have fucked up nitrogen and other cycles, requiring irrigation, supplemental fertilizer and more pesticides.

The climate crisis angle is just icing on the cake.
