Private message me for any detailed info. A lot of info is found in the library at dirtdoctor.com. My main ingredients for the health of soil & plants is Epsom salt, molasses, stone ground cornmeal (this is at the local grocery store) liquid seaweed, green sand & fish emulsion (at the local Nursery). Read the 3 articles at the Library, dirt doctor, "synthic Ferts". I can't help if you use chem ferts.
