Understanding Silicic Acid
For example, to achieve 13 ppm of soluble silica in the fertilizer solution using potassium silicate (assuming 8.5% plant available silica), the usage rate would be 0.6 g/gal, resulting in the addition of 40+ ppm potassium in addition to the silica. This excess potassium must be accounted for to maintain proper ratios of other major elements ...
