Can Arborists Create a Sustainable Rhizosphere?

2005 | J. Roger Harris, Virginia Tech
Creation of biologically healthy soils through the incorporation of composted organic wastes into the rhizosphere, should increase levels of “good” microbes, improve nutrient cycling and reduce soil-borne pathogens. Three different organic amendments will be added to three biologically distinct native tree species to see if the biological activity of the root-soil environment can be enhanced.
