Re: [compost_tea] for Elaine- fungi glue



We have known about the importance of glue made by organisms in soil for a very long time.  Many more organisms than just VAM fungi make glue. 

But, ok, USDA scientists finally got around to measuring a part of the glue that occurs in soil, and that's a big step forward for them.  Let's not rain on their parade. 

There's a great book by an Australian (R. Foster) called the Ultrastructure of Soil and he showed in hundereds of photographs that bacteria and fungi and worms all make glues that hold the soil together. 

So, why is it that the USDA scientists can claim they discovered "the glue" that holds soil together?  Ah well, they'll figure it out soon enough that they over-stated their claims.  There are a few million other glues that hold soil together. 

The point is if you can't measure something, you can't study it.  So, the USDA finally understands how to measure at least a part of the many glues that hold soil together.  This is good. 

Was there something more specific you wanted to know?
