SilicaPower is a biostimulant. Silicon (orthosilic acid) strengthens the cell walls and the epidermis of the leaf. The high concentration of Si in this product is easily absorbed by the plant.


SilicaPower in practice

  • The silicon (orthosilicic acid) we initially developed for ArgicinPlus can also be used seperately. It strengthens the leaf cellular walls and surface and ensures a better distribution of Ca and Mn throughout the plant. Si also helps reduce drought stress.
    With 3% orthosilicic acid, SilicaPower has a high concentration of Si that is readily taken up by the plant. This is clearly shown in this chart.


     Plant sap measurements 3 cut hydrangea cultivars clearly show increase in Si.

  • And specifically in fruit growing (pome and stone fruit): SilicaPower strengthens the natural resistance of your fruit trees and the firmness of the fruit.

Advantages SilicaPower

  • more intense flower colour: continues through to full bloom
  • thicker, harder leaves and better leaf arrangement
  • stronger cell walls
  • better root penetration
  • higher chlorophyll production, leading to more photosynthesis
  • plant resistance increases
  • transpiration decreases, less drought stress
  • redistribution of Ca and Mn, reducing the risk of nutrient toxicity
  • larger quantity of the CO2 fixation enzyme Rubisco
  • form of Si which is easy to take up :
    SiO2 cannot be taken up by plants, however the orthosilicic acid, (H4SiO4) in SilicaPower can
  • easy to use, via the fertiliser feeder or as a foliar spray
  • liquid, dissolves easily in the fertiliser feeder
  • highly cost effective compared with other silicon products
    (as less Si is needed for at least the same results)

  • pH neutral: no acidification required afterwards

  • 100% systemic: 
    the solution sprayed onto the leaf is distributed to the roots immediately

  • no residues, no growth inhibition, no re-entry term, no safety term
  • SilicaPower may be used in organic growth in the Dutch agriculture.

In other words: increase production and the quality of your crops.
Reap these benefits by adding the element Si, combined with the specific advantages of using SilicaPower. 

Articles available in English about silicon and SilicaPower:

  • Additional information about Si as an element and about concrete results with our silicon fertiliser in greenhouse horticulture and seed potatoes can be found here.
  • Articles in ‘In Greenhouses’ (the independant international magazine for greenhouse growers) about the element Si and our product SilicaPower show the major advantages of this product, as a result of which crops under glass can now be fully supported biologically.
  • Report about pot plants in ‘In Greenhouses' with Kalanchoe grower Slijkerman on silicon fertilizer ('In Greenhouses', January 2019).
  • Mr Jan van Luijk in the article ‘The need for resilient crops stimulates interest in silicon(‘In Greenhouses', August 2018)
  • And last but not least, we have listed the most relevant information about the element Si and our product SilicaPower for you in this printable pdf.
