Hi Elaine
Lime sulfur - calcium polysulfide - made by boiling calcium hydroxide 3moles
and elemental sulfur 12moles, in water gets calcium pentasulfide CaS5
2moles, calcium thiosulfate CaS2O3 1mole, and water H2O 3moles, then add
some cane sugar as a stabiliser and evaporate the water for a dry product.
(I pinched this info from an old post on BDnow list) Now our fertiliser man
takes this and has a microbe that just loves to munch on it - takes a year
to convert - and if he did know what was going on in that heap he would not
tell a soul. (I think he knows)
Most of us know of raw lime sulphur as a particularly stinky greenish yellow
brew sprayed on fruit trees to kill fungus? - I remember my dad doing this
and also helping him spray cattle for (I think) mange. It stunk like the
fires of hell, but seemed to work, I'm glad I was not one of the cows tho.
And I dont think the microbes in compost tea would like it very much.
There are a number of people in the eco fertiliser business claiming
biodigestion as a sales pitch and all some of them are doing is taking raw
stuff (like sulfur or rock phosphate and spraying on a bit of liquid fish or
compost tea type liquid, mixing it in and selling the result. How effective
is this ? probably hugely variable!
Cheers all
