I suspect the "toxin" is a microorganism of some sort and
solarization would work if the soil were spread out thin enough and
maybe turned over a couple of times during the cooking (with the
sun). Don't know how long this would take. Get good cooking if you
put the soil on the driveway if the driveway is ashfalt. Need to
put plastic under it too (any color will do for that.).
