An amazing post, thanks so much for sharing your "love affair" with soil.
It really is mind blowing what is going on in soil - there is a whole world communicating in there!
At a permaculture farm in New Zealand that I recently WWOOFed at we used "manure tea" during the summer - it was a mix of horse manure and comfrey that soaked in water for three weeks. Every time I distributed the manure tea on the soil I noticed an immediate growth of all of the plants!
