- The low intensity or high intensity
of light can significantly affect the photosynthetic rate in range
forage plants and very high light can damage stomata significantly
which can affect over all photosynthesis.
- Another factor is levels of
CO2 concentration for photosynthesis.
- Optimum moisture is also warranted
for photosynthesis.
- Extreme temperature can fluctuate
the rate of photosynthesis is the said zone.
- Unavailability of the plant surface
of the leave or plant for the photosynthesis, so grazing by
foraging animals would be a significant factor in the fluctuation
in the photosynthesis in the designated zone.
The responsibility
of range manager would be to control above-mentioned factors up to
limit; they can regulate or prevent grazing of various domestic or
wild animals in that area which can affect the photosynthetic rate.
With efficient management they may control moisture and temperature
in the given area thus regulate the photosynthetic rate. There are
various tier of photosynthesis and lower tier (C3 or C4) can be
managed and control effectively.
