fascinating observation. (
thinks ) So the extra heat does what? helps/hinders soil microorganisms?
Drys out soil -probably not in amazon
Would it help my plants in pots/
I have heard of people putting aluminium foil on pots to reflect light back up into plants; Charcoal would do the opposite.
This was an interesting post on another topic (PH):
It’s often handy to increase PH (decrease acidity) with “buffering” agents, such as solid wood or charcoal washed in the solution. This can limit acidity (low PH) without producing excessive alkalinity (high PH), and doesn’t require PH to be measured first.
