The science behind fertilizers

Do you know some books or articles that elaborate on the chemistry behind fertilizers?


I have taken organic chemistry so far, and inorganic chemistry as well. I am also familiar with the Haber-Bosch process. 




Asides from a general search on [Google Scholar](http://scholar.google.com), where, unfortunately, many resources are behind paywalls, here are some book references that may be of use for your broad-ranging request:


**Methods in Agricultural Chemical Analysis: A Practical Handbook** (Google eBook) (Faithfull, 2002) - some of this is available online through Google Books


**Fertilizer Manual** (UNIDO, 1998) - this, according to its contents has some information about the chemistry of frtilizers.


**Chemistry For Agriculture And Ecology** (Mido and Satake, 1994), A lot of this book goes back to basics, but chapter 18 is specifically about the chemistry of fertilizers.


**Agricultural Chemicals and the Environment** (Hester and Harrison, 1996) - once again, has some information about the chemical processes of fertilizers, with a focus on environmental concerns.


I hope these are useful.
