What do you think? My guess is that the
wood will soak up the nutrients and release them to the
hugel's biological community over time.
Ideally it could be pre-soaked. I fear that if the
urine is applied when the wood is already mounded, a significant portion will fall through to the soil beneath.
Every day, every season there is change, something new to observe, and constant learning. Permaculture has the dimensions of a life-oriented chess game, involving the elements, energy, and the dimensions of both life-forms and building structures (also with political, social, financial, and global implications).
