Effect of Human Waste on the Soil and it's Inhabitants ?

[Hal.]

I think this type of question may be interesting and a bit elementary to this area of Medical Science . But we are all here to learn in one way or another and people here sound like they like their bacteria , so here goes . Let's say for the purpose of this question that there is a person who regularly urinates on the same 100 lbs of plant soil day after day . Would a point be reached where the different types of bacteria present in the soil just can't cope with the chemicals present ?
