Hi Dr. Karve, This is a nice concise (and positive) report on your charcoal-in-soil experiments. Thank you. If you want, I am sure Christelle Braun would...

Michael, I don't really know the answer. From my reading on humus I got that it covered all long chain carbon compounds that were found in soil and were...
I have been giving this some extra thought, hence the reason it is so late. I suggest that the black bio material, not be called char at all. Char must be...
Coal has been subjected to usually the combined effects of heat and pressure - along with a decided lack of O2. Compost usually has had just the heat of...
Dear May How do you propose to grind or pulverize your charcoal? What approximate size range are you targeting? Applying fine dry charcoal would be a messy...
those were preliminary experiments, just to test the credibility of reports about terra preta. Now that we have positive results, we shall conduct more precise...

Dear Mr. Ballet, molasses, green leaves and starch have the same effect. The trick is to apply them in moderation. Use just 25 kg (dry weight) per hectare and...
