important word underlined.

Even if I'm using a slow release fertilizer should I still expect that it's harming the good stuff in the soil?
I wish I could find it, but someone posted a test that is rather telling. It was of a lawn that had been, and still was, on a regular synthetic program for years. SFI themselves did the test. They said that the fungal count was high, and the bacterial count was adequate.

Is there a certain element in fertilizers that does the damage and I just need watch out for it?
Note usually. In fact, most of the ions that are in fertilizers are produced by microbes themselves.

Is there a happy medium between all natural and synthetic?
YES! Bridge is ah-maze-ing!
