If fact nomatter if you bury charcoal or coal The effect is thez same. Charcoal is a very usefull combustible(for cooking as exemple),So if you bury charcoal you have to replace it by another combustible,like coal or a fossil fuel. If you replace it by for exemple solar energie or simply are more efficient,you can use the charcoal for another usage to replace fossil fuels,reducing the the co2 emmision this way. If you bury the ecomnomised charcoal you don't reduce the co2 emmision because you can as well use it for reducing use of fossil fuels. Anyway you turn it you can only reduce co2 emmission by burning less combustibles,no matter if you burn organic or fossil fuels. Buried combustible will be replaced by another combustible if there is no reduced usage of fuels. I really don't understand this 'save the planet' thing by burying charcoal. On the other hand,I'm kind of fascinated by the terra preta. They found out that charcoal has a positive effect on fysical properties of soil,soilorganisms and plantgrow. That's cool But did anyone had succes in making a soil like terra preta from scratch(infertile claysoil+organic matter,carbonised organic matter and whatever)?
