Your point is very good, and it is how they label and advertise their product. It contains a lot of the organisms and it specifically is labeled as ideal to be applied if a fungicide, herbicide or insecticide is used. They suggest applying it 48 hours afterwards in order to help reestablish the colonies that are disrupted by the application. Because I was still having to overseed and plant new stands this year I used a starter fert with siduron (which has worked great for me). So my spring apps couldn't use the tea...but I plan to use it for my fall ferts and potentially next year. I'm not comparing or suggesting they are the same product but I think the soil doctor product is designed to do something simliar as ICT Bill's compost teas. Again I have no idea what the real differences are, but because ICT Bill's program is for pros (minimum quantities are relatively high) I couldn't get a small amount of his stuff so I decided to try the soil doctor. They are the same company that sold me my poa supina grass, I owe you some pictures of that I believe.
