I've had a criticism of sheet mulching, to whit, newspaper is full of lead
but you can get the lead out of the soil by growing cover crops and sending
them to the landfill. Lone Rass! sez I, but does anyone out there in
cyberland know of ANY plants that can take up lead for transport elsewhere,
and how long does it take to say, deal with 800 ppm lead?
Urban folk legends! Ay caramba!
I say, dig it up and transport it to a sacrifice zone.
From everything I've seen lead in urban soils comes from #1, paint #2, other
human fabricated sources transported & concentrated- old burn piles, etc. A
paper I got from Inst. for Urban Hort. up in Seattle at the U of WA found
that "soil lead content did not correlate with proximity to roads, but with
length and intensity of human use of a site"
