Good point on the chemistry maikeru!
My concern would lie with the soil biology. How would diiferent fungi/bacteria react with TP with regards to any particular biome/ecosystem? I suppose this can be fixed fairly easy, but at what cost and at what reduction of return?
edit: I'm a newcomer to this idea btw...
