[Gasification] [Stoves] What is the soil chemistry forsolubilizing silica?

[Mark Ludlow]

Roger,

I was under the impression that phytoliths were a means of predator defense.
I read that rice has been grown virtually in the absence of silica, to no
major detriment. Earlier assumptions were that the silica added structural
stiffness but this notion seems to have lost credibility

Is it correct to assume that the silica uptake is the result of the
(diminishingly) small SiO2 solubility in H2O?

Mark

Dear Roger,
     Now that the plant process for silica is answered, what makes silica in

the soil water soluble, or at least exchangable? Plants do not need water 
solubility to take up nutrients, it just makes it easier. I know of grape
growers 
who have found that silica added to their nutrient mix has improved grape 
production and quality.
