Plant Beneficial Substance

Beneficial effects from Si fertility have included increased stress tolerance (disease, insect, drought, salt, nutrient imbalance, low and high temperature) and yield increases with or without stress.

The  form of Si in soils that is soluble and available for plant uptake is monosilicic acid [Si(OH)4], more commonly referred to as silicic acid or soluble silicon.

Silicon (Si) has been officially designated as a plant “beneficial substance” by the Association of American Plant Food Control Officials (AAPFCO) and plant-available Si may now be listed on fertilizer labels.

Silicon Labeling – The format below should be used for guaranteeing Soluble Silicon (Si) in a dry or liquid fertilizer. The method for Soluble Silicon (Si) is in the Journal of AOAC International, Volume 96, Number 2, 2013, pp 251-259. At this time the method is valid for dry fertilizer and will give a slightly lower number for liquids, but liquids should be analyzed by this method until a method is validated for liquids.   link to source
