Let me know if any of these links go dead.
Many universities aren't very progressive when it comes to organic agriculture but some are very good, so their recommendations for fertilizer, soil amendments, pesticides and the like may be a little suspect. They get their money primarily from the same corporations that make the synthetic chemicals they promote so, there's more than a little conflict of interest going on there. So, get what you can from it and call us with any questions you may have.
