Maybe not. We have the Co2 in atmosphere, which does incredible for plant growth!
Thanks to Co2 we will not need so much fertilization!
Our planet is massively greening, Our yields are also breaking all the records!
Plants need CO2 AND “food” (fertilizer, manure, organics-rich mineralized soil, etc.) for their metabolism. Just like they need water. None of these inputs can take the place of the other, all are needed. Air - food - water.
