Liquid fertilization is often used to supply silicon (Si) (Boldt & Altland, 2021), but Si is minimally soluble. Media components that provide a steady release of Si are valuable.
There are many options for Si media amendments, but Si release rate is not well characterized.
Our objective was to quantify Si release from media components to achieve a steady-state Si release as mono-silicic acid (H4SiO4) over time.
