According to one research paper, different fertilizers give different results in response to higher CO2. Some for the worse, some for the better:
"The results showed that the plants that received only NO3− as a source of N grew more slowly when exposed to a CO2 concentration of 760μmolmol−1 than when they were exposed to ambient CO2 conditions. On the other hand, in plants fertigated with only NH4+, eCO2 enhanced photosynthesis."
