What Fungi Do for Soil

摘要

In trying to think of a good way to illustrate the good effects that mycorrhizal fungi have on soil, my own experience in a garden should work. We had just moved to a new home in Camarillo, California, and the back yard that sloped downward had a relatively level area that could be transformed into a terrace about 15 feet wide by putting up a retaining wall of railroad ties. After the wall was built, I excavated the upper part of the terrace and moved that soil toward the wall, ending up with a level area.
