Let me start by stating that I am a long time visitor to the organic forum here at lawnsite. I have posted a few times, but mainly I come to try and learn more about organics. Organics interests me from a resource conservation standpoint. In my line of work, I see an unbelievable amount of resources and time wasted by uneducated or untrained LCO's. The idea of building up soil fertilty now to reduce or eliminate future inputs appeals to me. Unfortunately, I see a lot of claims made about organics but very little scientific data to back up these claims. I want to believe that there is a better way to maintain healthy landscapes without the huge waste of resources I currently see in the industry.With that being said, does anyone have any scientific data or articles to back up the claim that synthetic ferts are detrimental to soil microbiology.
