Frequently Asked Questions (FAQ)

1 Is Silicon safe?
Yes, it is safe to human, farm animals and plants
2 What is the different between SP1 and SP2?

Silicon Premium 1 is highly recommended for enhancement of weak and unproductive plants and oil palms trees and to apply as a starter dose for replanting areas to replenish soil's nutrients.

Silicon Premium 2 is for long term maintenance application to prevent the recurrence of locked-in nutrients.

Both can be easily applied on the entire field as basal dressing during plughing/harrowing or around the base of plants and oil palms trees

3 What is the shelf- life?
Silicon should be stored in a cool and dry location. In this way, a shelf life of 2-3 years can be expected.
4 What is soluble silicon, and why is it important to crops management?

Soluble silicon, the "plant available" portion of the silica, makes up the largest portion of soil chemistry. It is found in plant tissue in amounts that are equal to its essential nutrients (N, P, K, Ca and Mg). In certain crops, silicon is found at higher levels than most nutrients. A management program that includes silicon fertilization is essential because:

  • Available silicon is leached from the soil by normal growth demands and weathering while it is typically not replenished by any fertilization program.
  • Plants grown in soils with high soluble silicon levels have a reduced susceptibility to disease, drought, and other plant stresses.
  • Silicon has been shown to reduce phosphorus leaching while at the same time increasing phosphorus plant availability.
  • Silicon’s activity in the soil matrix has been proven to improve micronutrient uptake (boron, copper, iron, manganese, zinc), and reduce toxic metal uptake (aluminium and sodium).
  • Silicon promotes root rhizome development and size.
5 Has there been any significant evaluation of the importance of soluble silicon to plant growth?

Yes. The evaluation of silicon in agriculture has been ongoing in earnest for at least the past 25 years. In fact in 1999 the University of Florida, and others sponsored a "Silica in Agriculture" conference where much of the latest information was published.

Dr. Emanuel Epstein, University of California (Davis) has published extensively on silica and plant health and has verified that silicon absorbed by plants:

  • Is deposited in and strengthens cell walls,
  • Results in plants being more resistant to insect attack, disease, and fungal invasion
  • Makes some plants more productive, increased yields.

Other Studies (Dr. J Chen—University of Florida, Dr. James Menzies—University of Laval, CA) identified additional benefits of Silicon including:

  • Increase in resistance to toxic elements in soil,
  • Improvement in resistance to frost and drought
  • Increased disease resistance

Studies by the University of Florida of Silicon in the Environment have Identified:

  • Decreases in the leaching potential of phosphorus applied as a fertilizer or manure amendment.
