  • Silicon which constitutes approximately 28% of the lithosphere, is an essential element in the life of plants and other living organisms. In plants, it accumulates mainly in cell walls, reinforcing them mechanically. Dicotyledonous plants contain much smaller quantities of it than monocotyledons.
  • Silicon is present predominantly in the polymorphic Si02 compounds.
  • Liquid silicon forms are represented by aqueous solutions of silicon acids or salts thereof, which are transformed into organic silicon as a result of chemical processes occurring in plants.

  • Silicon also reduces the abiotic stress (stress caused by external factors) by increasing the tolerance of plants to low temperatures, intensifying photosynthesis in low light intensity, protecting against the toxic effects of high levels of manganese and iron in the soil, and reduces the toxic effects of aluminium on root growth (as silicon compounds are a selective ligand of aluminium ions). Silicon also has an important influence on the regulation of nutrient uptake, which is most evident in the case of phosphorus uptake. Fertilisation with silicon compounds allows for much lower rate of fertilisation with phosphorus compounds wherein maintaining similar yields.
  • the use of water-soluble silicon compounds in the cultivation reduces the susceptibility of plants to pests and diseases, and stress caused by adverse weather conditions, and also increases the. production of biomass and strengthens stems, and therefore reduces lodging.
