Do salts from syntheic fertilizers really harm the soil food web? I hear it from both sides. Any authority out there? Perhaps someone knows an university study. It is not easy finding the truth of the matter often times. Here is another one I am looking into, Neem oil does it build up a resistance to insects? I heard from someone I respect that the Dept. of Agriculture was excited about this product until it was discovered it does build up a resistance to insects. I guess I could try to find how to get through to that monster of an organization to know who is saying what. And I will but since I'm new at this and I am among the tried and proven I wanted to ask you out there first.
