Miricle Grow

Has anyone found an article that reports scientific testing of Miricle Grow and what it does to soil organisms? If so, would you please send the link. Thanks

I found this while looking for "Alaska Fish Fertilizer" for my roses. Is this something along the line of what you were looking for?

The issue isn't one of what's in a fertilizer, the basic elements are generally the same. Even "organic" fertilizers need to be broken down into inorganic compounds before they can be used by plants. It's the amount of fertilizer you use. Most people subscribe to the "more is better" school of plant feeding, and much of what you spray on your plants goes to waste. Over time, that's what may cause problems for the soil because of a buildup of salts in the soil. A product like FertiSorb uses much less fertilizer per application since none of the nutrient is wasted, it remains in the root zone until taken up by the plant. Less fertilizer, less impact on the surrounding soil. It's that easy.

the difference in the organic is is that you don't have the salts that you do with the chemical fertilizers. salts do the burning. green manure has a lot of salts.
the worms don't like salts either. it takes a while longer usually for the nitrogen to be released in an organic fertilizer than a chemical one.
they usually have more nitrogen than labeled, because it's not immediately available like a chemical fertilizer.
so for immediate results the chemical fertilizers make a big difference but for heavy fertilization for the long term the organic will win out because you will have no salt buildup.
