OK, this is from an ag class 35-years ago, but I’m sure it holds up: Yes, pumping CO2 at a plant gets significant gains.

CompactFlax@discuss.tchncs.de 1 day agoMy understanding is that nutrition has got more to do with selective breeding, soil microbial ecosystems, and depletion of plant micronutrients - we focus on macronutrients (N-P-K) in fertilizer.

Micronutrients are generally represented in foliar fertilizers or seed treatments, not granular fertilizers. So things like boron, copper, zinc, sulphur, manganese, etc are applied by spray, generally, since there is better uptake via leaves than roots, though much of it will hit the soil for later use.
We’ve even identified fields where we applied a certain amount of gold, which is used for better disease resistance.
