Bio-lime sulphur -

What exactly is the chemical formula, and what do they mean, BIO-lime
sulphur.

Typically lime comes as calcium hydroxide or calcium nitrate. Correct me if
I'm wrong here, but I've tried to get sales reps to tell me and they often
don't know or
I'm not sure they are telling me the truth.

If you then add sulfur, some of that lime will be converted to calcium
sulfate.

When you make this calcium-hydroxide + calcium sulfate mix "biologically
activated", typically some of the calcium is now tied up in the structure of
the organic material. It is not strictly an inorganic material anymore.
Thus it is much less detrimental to the organisms. The osmotic shock
(water-sucking-up) ability has been decreased.

So, addition to compost, soil or to tea is much less detrimental than the
inorganic forms. How much less? Depends on how much is biologically
complexed and how much is left as salt (osmotic shock). Easiest way to test
is to determine active fungi before and active fungi after addition.

Hope this helps!
