This is the home for a book, "Fertile Soil" by Robert Parnes. It is the
result of a literature search during the operation of Woods End
Laboratory, an agricultural soil-testing facility in Maine. The lab
served farmers and gardeners throughout the nation.
The book is out of print but has a secondary market. Consequently and
because of its unique features, an edited and reformatted version is
offered here under a creative commons license retitled as "Soil Fertility."
