Have any of you used lichen or moss as a nitrogen fixer.
...A lichen is the result of a relationship between a fungus and a photosynthetic organism, usually one-celled green algae or cyanobacteria (“blue-green algae”). (Cyanobacteria are a group of bacteria that can photosynthesize, using sunlight to make food from water, carbon and other nutrients.)... Lichens also fix large amounts of nitrogen from the air and help moderate the humidity around them. http://theworldlink.com
If you could post photos of your experience or research links it would be great.
I don't have any soil on the top of the rock, other then what I brought in. The pine forest floor is pit and mound with blueberries. I want to recreate that in a forest garden made of hugel beds on the rock. That's how I would use the lichen... To mimic the forest.
