The major reason revegetation is vigorous after a burn forest or grass is from the reduction of fixed minerals to soluble by the oxidation. There is also a mineral concentration by  the reduction of the carbon.

Jeff and...There's a lot of different opinions on the value/harm of the "tars" in the soil. My instinct says "no-no!" but some people drink the distillate and think that it is God's blessing!If we observe natural phenomena, for instance forest burns (which, presumably, have multiple regimens of combustion, from hardly-at-all to pure ash) we see that there is usually a strong recovery after a burn, but the ecosystems are usually not replaced, intact, but forced to begin their long, progressive cycle once again.A study of 19th-century charcoal kilns in the Eastern U.S., show that there is a lasting effect on the sites on which they were located. On the other hand, many suggest that the aromatic compounds produced during pyrolytic combustion are valuable components of the signaling network that tells seeds and the soil ecosystem that the sky has opened and that the system has an altered competitive structure.Maybe a little is good; and a lot is bad. But despite the evidence that many of the polyaromatic hydrocarbons remaining in the char produced for biochar applications is carcinogenic, some certifying bodies have declared it "Organic" and suitable for unrestricted use in agricultural applications.Who knows?Best, Mark -----Original Message-----

Personally I would be reluctant to promote this just because of the danger of starting forest fires and what not.   > So we really have no excuse for cleaning up TLUD gas if we wish to.   As long as we don't place the tar laden charcoal in the soil but use it as a fuel. In other words clean charcoal added into the soil is much better that adding charcoal that was used to filter toxic waste.    > Compare to natural gas at 1000 Btu/ scf.  Locally the troops have landed and marcellus shale gas is under production. It's been stated that this type of well will last for 30 to50 years and beneath that even more gas. Already, locally, the price of natural gas has dropped.  Best regards,  Jeff  _______________________________________________Gasification mailing list to Send a Message to the list, use the email address Gasification at bioenergylists.org to UNSUBSCRIBE or Change your List Settings use the web page http://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers,  News and Information see our web site:http://gasifiers.bioenergylists.org/
