USDA says silicon helps citrus

(1/3) > >>

Walt:
Today Citrus Industry news says 50 to 100 ppm improves citrus health including disease resistance and cold tolerance.
It also said several products have come out with silicon at those strengths.  Also said several products already had silicon in them but lumped silicon in "inert ingredients".  Names of such products weren't mentioned,

drymifolia:
Diatomaceous earth is an excellent source of silica, and can be used in potting mixes similarly to perlite.

Seanny:
Rice hulls are 18% amorphous silica by weight.
I’m using them and DE.
Can’t have too much dirt!

mikkel:
I read the article, but I am not sure if silicone is in english the same as in german...
Is there a chemical/sientific name of it?
Silicone in german is something you use to groute the tile in bathrooms.

--- End quote ---

Silicone (with an "e") is a plastic-like polymer compound made from silicon (the chemical element). Plants can use silicon dioxide (also known as "silica") as a source of this element.

Silica is what makes quartz crystals (and glass), and is the main chemical in most sand and many types of rock, but can be nearly absent or inaccessible to roots in some soil types.
