Ya know, the mention of photosynthesis brings things back around to
the question of what is being taken away at harvest.
Isn't the majority of the dry mass of plants generated by carbon
fixation during the photosynthetic cycle?
So if we remove the nitrogen and the carbon from the atmosphere from
the corn harvest equation, isn't it more likely that we are talking
about a net loss of a few pounds of nutrients , as compared to a net
loss many times that from erosion?
And there should be a net gain in carbon from the unharvested parts of
the plant.
Yeah, the microbes and higer critters need to have some of that carbon
put back into the system to support them, but I think that is a
different issue thanworrying about "what is being taken away".
Of course this is all based on my recollection of high school biology,
and it has been a while since I looked at the reaction.
