• What are air bubbles in the soil?

Today I discovered that bubbles are forming in the soil and periodically bubbling up. What is this? Is it dangerous? And how can I deal with it?

This indicates that your soil is heavily contaminated and there is active hydrogen sulfide release (decay). Siphon it out.
