I spent a while trying to figure out which stackexchange site in which to post this question, forgive me if I got it wrong.
A number of scholarly articles indicate that concrete can leach calcium compounds under the right conditions. Could they ever wick upwards against gravity through dry or water-saturated soil?
An example would be a raised bed of soil with wooden sides and a concrete floor.
P.S. I also wonder about plastics leaching upwards, but this is admittedly most likely a different question.
