Ok so we have two web sites that claim organics are better than synthetics. Before I buy into any of this I would like to see one scientific study that compares synthetic fert to organic fert. I have a huge lilac in my own yard that has not only been treated with synthetic fertilizer the lawn surrounding it has had synthetic fertilizer for over 10 years. The lilac has more blooms than I can count each spring and looks great. Is it possible that there really is no difference, that if the right balance of nutrients are supplied the plant ( any plant for that matter) don't really care where the food came from. From my own experience I just can't see a significant reason to lean to organics over synthetic fertilizers. I'm sure organics are fine as a plant food source. I just don't believe they are superior as you claim.
