<p>Any charcoal may not have adsorbtion properties I demonstrated with Alterna and California gasifier char.I have a good reference on this you can read. Rather than lose another season on a garden patch I would recommend. 1. prescreening actual soil toxicity to broadleaf seedlings and 2. Using grosafe applied as a slurry at 300 lbs/acre worked in 6 inches. With charcoal of unknown property you can powder it and try a challenge test with caseron and radish or mustard…</p>

This is fascinating and exciting news. Thanks for sharing it with us. I am still pretty bitter over my loss of production from last year's tainted compost from Smit's Dairy, but this is great to see.

<p>Is simple screening technique that gives result in few weeks. I used mustard seed. Easy to challenge with off the shelf herbicides. </p>

<p>Might be interesting to try to screen your contaminated soil. Will determine if contaminant is still present. </p>

thanks Richard for working on this important topic. Good results with the charcoals! Just to throw an idea into the mix: I wonder how mycoremediation techniques would work against herbicide compounds? Inoculation with Stropharia, oyster sp. etc... or perhaps they wouldn't like the herbicide treated soils at all. I used contaminated soil in two of my garden beds last year and my crops suffered. Maybe I'll throw some charcoal in there.
