Could there be a place for potassium silicate in compost tea?? (probably no=
t for orgainic cert)
Any one with ideas care to comment.
I believe there is a relationship between Silicate availability and fungal =
biomass in the soil.

Hi Mike,
You addressed your reply to me, but Titel is the one with the
good results. It got me to thinking that maybe his success is
tied in part to the silica rich rock powder he's using. We've
been told by a PM (powdery mildew) expert that Silica can aid in PM preve=
ntion and it was recommended that we use potassium silicate as a soil appli=
ed fertilizer. The problem is that as far as I can tell potassium silicate=
is not organic. Seeing that Titel was using aluminum silicate (pyrophilli=
te), I would like to give it a try since it is mined and therefore should =
not be a problem for certified organic
production.
Here is a copy out of Titel's original post that gives his recipe:
<><><><><>
The tea (2 batches) was brewed for 48 hours with a
water pump, venturi and bag extracter. The temperature
ranged from 65 to 88 degrees. The ingredients; 100 liters of
spring (well)water, 1 liter of black strap molasses, 65 ml of
fish hydrolisate; IN BAG > 5 liters worm castings, 250 ml of
Norwegian kelp meal, 65 ml of rock phosphate granules, 65
ml of pyrophillite clay powder.
