My rocky soil has suffered from multiple years of drought and lacks organic matter. Leaf matter from last fall did not decompose and I only saw two worms when moving most of the pile. Am guessing lack of oxygen for the leaf pile. I am playing with my usual lazy methods of cardboard, cedar bark and leaf matter from a big leaf maple to create some new beds with success. It will take years to get the soil depth. I saw a documentary about the extensive civilizations in the Amazon that were discovered and the fertility of the soil they created. Has anyone created inoculated Biochar? Or know some of the basics? Hügelkultur beds are incredibly productive in my previous home, but I was starting with great soil and lots of living organisms obviously present in the soil. It also took a few years to transform wood to soil. Maybe I am just impatient but I am exploring ideas for adding microorganisms into the soil quickly. Easy is best because I am a simple, lazy gardener. Any suggestions would be greatly appreciated.
