[nafex] Re: Black Walnut Roots

I skimmed the book for an answer to your question and although there 
is a lot of material on soil, about water and oxygen and plant 
physiology, it did not explain your questions. I have to say I don't 
know what they meant by that and I can see how it seems contradictory.

Oh, as far as root symbiosis, I think that they simply mean that the 
persimmon benefits from being next to the walnut, I don't know that 
the walnut benefits. The book was saying that the relationship should 
be investigated, I don't think there is any science proving that 
there is a symbiosis in its literal meaning, could be wrong.
