Thanks for your comment. I was thinking more of landspace rather than fertilizer, knowing little as I do about all the resources needed for agriculture.

Just for clarification, are you saying jatropha ethanol would result in a net gain for phosphorous, or a minimal net loss?

Pepper, that amount that is removed in the oil, and burned in an engine would definitely be lost. I'm just guessing (I'll try to find some proof) that most of the phosphates will end up in the remaining biomass which will probably, in the end, be fed to cattle, and returned to the earth as manure, or some derivative, thereof.
