Abstract
In order to examine the effect of elevated CO2 and soil N, I
completed an experiment in which photosynthesis levels
were determined for different CO2 and N treatments for
Achillea millefolium L. and Agropyron repens (L.) Beauv.
For this experiment I predicted that higher CO2 levels would
result in higher initial or instantaneous photosynthetic rates.
I also predicted that addition of N in soil treatments for
Achillea millefolium and Agropyron repens would result in
higher photosynthetic rates. For the combined effects of
CO2 levels and soil N levels, I predicted the following result:
elevated CO2 levels would cause lower photosynthetic
rates with N addition than N addition alone. In addition to
these three aspects that were examined I predicted that
CO2 and N would have different effects on species due to
the specific nutrient requirements of each species.
