Wait, decaying organic matter supplies the plant with CO2? Is there a source for that? Because that seems to be some wild science, especially because air, and thus CO2 molecules, move away from the soil and the plant at the speed of air aka the speed of sound, which is 300 meters per second. If you have everything else optimized, then yes having double the CO2 today as we had 300 years ago gives you a much better plant yield on say your corn. But, it is still bad overall. Including for farmers. Because you might have to stop growing corn and start to plant olive trees, wait 15 years, and then harvest your first bit of olive oil in your near little desert.
