Silicon is one of the most important fortification nutrients for plants. Until now, it has been inefficient to try to deliver Silicon to plants. Often Silicon (Silicate) formulations are high in pH and not compatible with other nutrients. Plants store Silicon in the Opaline form, which is the form of Silicon provided by PRO N Silica. As a neutral molecule extracted from plants for use on other plants, the Opaline form of Silicon (Silica) should be delivered with a neutral carrier such as Plant derived protein nitrogen. PRO N SILICA is a highly concentrated powder which contains both the carrier Protein Nitrogen (14%) and Opaline Silica (20%)
