Actually, there's one way that your theory works. Set fertilizer = 0.
Would be a nice summation of your logic.
You quoted _a_ logical fallacy, but not the correct logical fallacy.
You quoted the fallacy of non-sequitor (it does not follow).
You should have quoted the fallacy of _composition_.
http://en.wikipedia.org/wiki/Composition_(logical_fallacy)
To recap:
"A fallacy of composition arises when one infers that something is true of the whole from the fact that it is true of some part of the whole (or even of every proper part)."
