"The silicon content of soils is (very) high, with an average of 28% Si by weight. The vast majority of Si compounds in the soil consists of silicon dioxide, silicate minerals and aluminosilicates, none of which are available for plant uptake. The only plant bioavailable silicon compound is monosilicic acid (MSA; synonym: orthosilicic acid: OSA), the concentration of which is (very) low in the soil."

Many folks are using a product called Agsil 16H. It's potassium silicate. We carry it on our website. It's what is in most of the "silica" products online like Dynagro ProTekt, just in a powdered concentrated form.

Here's a good article on the benefits of silicon: https://ufdcimages.uflib.ufl.edu/IR/00/00/17/26/00001/EP07500.PDF

I have used Sili-K liquid and the Agsil 16H that Tad sells sparingly over the last 2 seasons. My advice is to test the fertilizers that you use in a jar test with these products as they tend to precipitate out. May want to use them by themselves especially with drip tape and rinse well.
