Age Old Commercial Silicon is a stabilized dispersion of silica nanoparticles that help optimize conditions for resistance to abiotic stresses in plants. Unlike other silicon-based products, in dilution, it is tank-mix compatible with other fertilizer inputs, and won’t precipitate and clog irrigation equipment. It carries a lower pH than most silicon products, and is a low use-rate product. Because of this, it won’t change the overall pH of the fertilizer solution.
