Fresh Starts said:Do you know of a lab that tests leaf tissue for silica content?
To be fair, I'm still trying to understand what that post meant.
I don't see why any lab that performs tissue analysis shouldn't be able to include silicon in the testing. Its not going to be a common or routine test for them, but if asked, any agricultural lab should be capable of doing the analysis.
The problem is finding a lab that is close enough to you, that you can hand deliver, and that is willing to take your tissue.
fyi, my recommended concentration of any element in the working solution is highly variable according to the fertigation frequency. If you are fertigating more than once a week with silicon, the level in the working solution can and arguably should be lower than 45-50 ppm Si. Hence the table.

If you really want to be as up to date as you can be as a layman, read that book. I will loan you my copy if you are serious.
I'm doing something similar @Fresh Starts Using the AgSil Stock @ 2.5mL 24.106ppm with every feeding so that's about 3 times week and shit is blowing up compared to Aptus silicon b/s way thicker stalk and over all healthier plants.yeah I fertigate using silica in every irrigation event and I irrigate at three times a day during peak bloom depending on plant metabolism. That book is a great recommendation from what I can see using the provided link. I will add it to my list books to order. I was not saying that the amount of silica in solution was wrong BTW- I was just stating that silica levels can be lower and the positive effects of the ion will be present. Whether or not the benefits are adequate is relative to species and grower. Appreciate the info as always @Quantrill
So use up that sample the hydro store gave you then head to CHN and grab some Agsil 16H mix up a gallon and have 3.25% plant available silicon and save some bread.

Soluble silicon is not the same as some bioavailable silicic acid. Water solubility % is not the same as plant available silicon. If I'm interpreting the original post's chart correctly, the percentages is just for water solubility, meaning how much of the silicon/silica dissolves and is usable in the feed water, but like I mentioned, it does NOT translate to what is actually instantly available to the plant. Don't let the solubility % confuse you with availability.
Willem Adrianus Kros is the discoverer and inventor of water soluble and stable bioavailable silicic acid as far as my brief researching goes.

The easiest 'layman' method of being able to tell if your silica additive is a true silicic acid, or just a run-of-the-mill potassium silicate variant is whether or not it drops or raises your pH. True silicic acid is VERY acidic and should lower your pH in pure water and should also test at lower than a pH level of 2.0 or less if testing the straight concentrated liquid. Powered or liquid potassium silicate is basic and will raise your pH. I'm sure you've heard before that you can use standard forms of silica to raise your pH rather than using a conventional 'pH UP' liquid.
wrong again, you seem to be parroting bullshit you heard from the folks scamming you.chingling said:True silicic acid is VERY acidic and should lower your pH in pure water and should also test at lower than a pH level of 2.0 or less if testing the straight concentrated liquid.
wat.Peace,
Patrick Flanagan crystal energy shines through the process of getting silica to plants with nano /angstrom fully soluable product @ 45/1 bottle or 3@90, lasts a long time on one 4 oz bottle...food grade.penetrates all membranes...use with Georges distilled Aloe...
