It is very exciting for me to tell you that the pea experiment is showing more and more results. Note: there are still flaws in the setup and the experiment is for proof of concept only.
The picture is telling us two stories. First, the biochar peas are now suffering from what I think is some kind of infection or insect feeding. Small marks on the lower parts of the stem are clearly visible. The yellowing leaves could also be a sign of too much water (we had a few days of heavy raining and the pots have no hole for excess water to drain out). This only proves the water binding capacity of biochar. This hypothesis is also supported by higher moisture in the biochar pot. (note to self: get a moisture meter)

Secondly, there are now peas growing on the biochar plants as a result of earlier flowering. I can only speculate on what effects earlier flowering and thus earlier formation of peas can have on agricultural uses of biochar, but I think it is a good sign.
