  1. Thanks for the response. I am noticing myself that the char is taking from the soil at this early stage of study. How long does it take to mature a bit? One season? I believe you in the organic bio side of TP. The biology in the TP is what the researchers are looking at from what I have understood from various publications that talk about funded research. I personally am 'filling' most of my char with all sorts of organic materials. Has there been any success by anyone soaking in urea or whatever and using it as a fertilizer? Would the natural soil biology enhance the urea char, while
  2. Well that didn't go anywhere. Is it likely that there are not enough experiments that have produced results yet?
  3. Has anyone been conducting experiments that they believe has produced some results? It would be fun to know WHAT has been tried and WHAT the correlating results may have been. Even, dead end, reports would be of help to those of us trying to create tp our first year.
  4. Time. That's what I was afraid of :( Time and patience. Oh, well. Thanks for the reply. It helps me sense that I am on the right track, by soaking. Has anyone had any extraordinary results by growing stuff in char? That would be a fun thread.
  5. Thanks Phillip, that helps. :naughty: It is then safe to assume that the CEC is a function of how char reacts in the various soils and not so much as what it is made of. Condos for the wee beasties is probably the chief contribution to any soil, even so.
  6. So :) do we know if pine char is lowering CEC in the soil? Could it be that low temp charring that retains the oils of pine cause that? It seems that pure char burned at high temps would be just a lot of carbon, regardless of what it was made from. This gets more confusing all the time.
  7. Thanks Essay, I did get to where you had posted a list of ideas for the social group, but not the inner circle by any means. I checked out the url you posted and was able to read page one. Here they claimed high acid exchance and high CEC on High temperature char. I liked the idea they were innoculating the char with various things. You were the first person to indicate that it would be a good idea. This article was the second. You'll have to make a dvd for school kids to pique their interest in chemistry. Call it: "Naked Protons!!! Bound,,, For Food" All the kids will be thinking
  8. That is what I meant, exactly. :phones: Like an empty container filling itself with whatever it can adsorb. Perhaps the different things that are added, affect the ph? There really seems to be alot of differing ideas. The CEC difference, being a BIG one. I looked through the 4 pages for a "Terra Preta Social Group" but couldn't find it. I wonder if plants will grow in pure char? The plant would be required to survive off of whatever the char was filled with.
  9. Ok, thanks. That makes sense to me. It is the scantily clad carbon that does the filtering, so we would automatically eliminate the plant residue as much as possible. For that process. In the TP idea we want to preserve some plant residue for the wee beasties. [if I am following correctly] What if, instead of leaving the residue of the plant, we went with the high carbon char. Then filled the char's condos with something other than the original plant material that the char was made from? Does it work that way?
  10. Thanks for the forum sites. This one I found to be disturbing. Thanks for the website. I didn't find anything there but did find that hardwoods make soils have a higher ph the softwoods (conifers) and an interesting fact that hardwood increased the CEC of soils but conifer actually decreased it. This from "Ameliorating physical and chemical properties of highly weathered soils in the tropics with charcoal", Glaser, Lehmann, Zeck 2002 I thought it was the carbon that provided CEC rates. I didn't go to the article yet, but may have to see these ideas in context. I have a large pile of pine
  11. That is interestting. Pine needle chars being slightly acidic whereas briquettes are in the 8 or 9 range. Are briquettes produced at high temps as the needles were? This pyrolysis leaves little or no plant residue behind? Talking about 'activated charcoal' for the fish tanks. Now am I correct in understanding that this type of charcoal is fired at low temps? Does this type have plant residue, that goes into fish tanks? Sorry for the excessive questions, it is just that reading through the forum I seem to keep forming different ideas about which is what :hihi: Thanks guys, and it will
  12. Ok, thanks :hihi: At the end of the season I will test the ph of my TP mixtures. Then compare with the various soils I used for those mixes. I wonder if it would be accurate to test the ph of groundup char itself?
  13. As I was reading through the newbie thread and I found this question, that I had wondered about myself. I was thinking in the context of a worm bed to provide adsorption to newly charred chunks. Also if it was in an actively composting compost pile. Has much been done to figure out the best ways to prime charcoal? By priming, I mean filling the condos with the 'wee beasties' and nutrients. I appreciate for any ideas.
  14. I was not talking about any soil in particular. Just the interaction between char and ash. One being low ph and the other being a higher ph. If the two together balanced out enough so as, not be a concern in the soil?
  15. I had also read that pine char lowers the ph when oak char increases ph. (or vice versa). Is this a significant ph change either way? Does it make sense that keeping the ash with the char keep us close to neutral change?
