Re: [compost_tea] Copper and CT
So sulfur applied to the soil, either in granular or wettable form is harmf=
ul to the fungi in the soil? Sulfur is used in many lawn applications to op=
en the soil, lower the pH, and chelate some nutrients. Is sulfur helpful to=
the lawn, partially, because it gives the bacteria the upperhand over the =
fungi population? What does this do to the biology, or fungi, necessary for=
the trees growing in the lawn?

Reports in the scienitific literature say copper is toxic to a number of =
bacteria at 3 ppm. As far as I have been able to discern, it is the bacter=
ia that are more susceptible to copper than the fungi. But we have not don=
e testing on copper concentrations in tea, mostly because I am happy with t=
he research papers on copper toxicity.
It's the sulfur that seems to take out many of the beneficial fungi. We =
have some observation of this, but also a fair number of research literatur=
e papers showing the same thing.
