okay so what i see is,they have done signifcant studies with char,and several fertilzers to include chemicals,,as usal nothing out preform chicken manure,,thats a no brainer,,but at same token ,there have been no studies of char mixed with rock dust,,there is the minerals needed to provide what there trying to acomplish or come up with,in my opinion,,so say it is true,all im seeing that it has to be reapplied more often than folks thought,,i watched a vid last night,that was made in japan,,these fields and villages have been abandoned for years after a tsumi hit the coast and destroyed everything in its past,,the 3 boys took on the job of trying to make something of this place,,they took standard garbage and done the same methods of the char,furnace or what ever you call it ,kiln i guess,,but anyway they took the char,from bio mass of wood and garbage combined with rock dust,,took 2 2 acre fields and planted rice,,1 field with 1 without,,now keep in mind farming had stopped because of salt from the ocean,,but they planted rice in both fields,,the char field was so much work cause the weeds were soaring to a point of almost out of control,they also took this same waste,wood and rock dust mix and feed to gold fish,,2 tanks,,the fish in tank with this mix doubled the size of the gold fish and they were in a frenzy of health to have more,,sounds like a steriod right,but not,,with those finding they decided to release into the char field a certain number of ther fish in the floode fields ,done same thing in untreated field,,at harvest of rice and fish,,char field was the best and sweetest taste and fish a had quadrupled not only in size but in spawn compared to the other field,,the untreated field didnt even spawn and from salt still in ground hardly had any fish,,so what im thinking,,if i was to overdose on a drug,,and i have,,they use charcoal then pump out your gut,,when my dogs have upset stomach,they hunt charcaol and i cant keep there ass out of it,,it got top be good for something,,like i said gonna be hard to convince me of it harming the ozone when my eyes and stomach tell me difrent,,there was also no mention of the char being charged with these nutrient the used,,that for a fact has to be done ,or it will suck all the nutrients you have in your soil out,like a sponge,,this might also be reason why they didnt produce as well,,just saying ,there is a lot missing from there studies,,and again no mention of what water table they used,,was it flooded fields from mother natures rampage which in turn send all the chemicals down hill to these farms are forest they claim,,was it controled envorement with treated water,and so on,,this might not seem but jibber jabber,,but as you also know in the weed we grow make a huge difrence
