[Terrapreta] TP growing back--was: TP theft.

[rukurt at westnet.com.au]

Hi folkes,

I keep seeing mention of TP soils being mined and then, over a period of 
some years (20?) "growing back". 

How?

Is the charcoal in the soil mysteriously multiplying and moving out into 
the soil?
Is someone clandestinely adding charcoal to the soil?
How does the allegedly "grown back" TP soil compare with the original 
soil that was carted off?

Anybody have any ideas?

Perhaps erosion is moving soil from unmined TP areas into the holes left 
by the mining?
