This is an Open Access publication of Taylor & Francis Online.
I just read one article on mycorrhizal fungi and globe artichokes - http://www.tandfonline.com/action/showMostReadArticles?journalCode=ucsu20#.VJBzLRB7-kw and found it interesting and informative. It is an academic journal, and written as such, but there's a valuable permie takeaway from this article - a specific mycorrhizal fungi for innoculating globe artichokes for maximum performance.
I am sure there are other papers with helpful information in this journal.
And there are numerous other journals published as open access that can be found on the Taylor & Francis website.
