(Another former Iowa farm boy) This is a CO2 sequestration process, and one still in development. The carbon in the corn stalks is obviously pretty neutral—it’s the petroleum for tractors, drying, and fertilizer that are the CO2 emissions problem.

For soil health, I think you’d want your renter to go no-till (if isn’t already). And then for emissions, look into putting solar panels wherever, seeing whether there are electric/heat pump dryers available (???) if you have drying bins, and encouraging renter to use biodiesel.
