just wanted to share some links i have found on the net which i thought were useful.

The Diagnosis of Mineral Deficiencies in Plant by Visual Methods
(vegetables and fruit listed)

and the Holistic Agriculture Library, that puts up out of print texts on agriculture ... lcome.html
2 books of interest to aquaponians among many others could be

Weaver, John E. and William Bruner. Root Development of Vegetable Crops. New York: McGraw Hill, 1927.
The classic study, filled with species-by-species illustrations, each worth tens of thousands of words to someone who wants to grow vegetables better. PUBLIC DOMAIN.

Weaver, John E. Root Development of Field Crops. New York: McGraw Hill, 1926.
It is difficult to restrain myself from praising this book with several hundred words that would be inappropriate in a "card catalog" such as this. However, Chapter I contains what may be the best basic soil's manual there is; Chapter III suggests magnificent realizations about how to grow plants with an awareness of their root activities and how that effects what one experiences above-ground. Anyone intending to grow plants well needs to study both of Weaver's books, especially the first portions of this one. Of interest to Organic growers will be Weaver's frequent citation of Albert Howard's researches in India. PUBLIC DOMAIN.

hope you find this useful
