Basically there are 2 types of plants: those who move CO₂ actively towards an enzyme (RuBisCO) that absorbs it to prevent it from erroneously taking on oxygen and wasting energy, the so-called C4 plants; and plants that do not (C3 plants). ...

... It seems that this perplexing result may be because as time went by, less nitrogen was available to fertilise growth of plants in the C3 plots and more in the C4 plots. So the effect was not just due to the plants themselves but also to their interactions with the chemistry of the soil and its microbes.
