Silicon is Essential for Rice

By: Jian F. Ma ,  Research Institute for Bioresources in Japan

A review of literature and trial work by Jian F. Ma from the Research Institute for Bioresources in Japan shows that there is clear evidence that:

  • Silicon is an essential element for higher plants, such as rice because “it has been shown that Si deficiency causes various abnormalities in the plant”
  • Beneficial effects of silicon are increased photosynthetic activity, increased insect and disease resistance, reduced mineral toxicity, improvement to nutrient imbalances and enhanced drought and frost tolerance
  • Silicon is probably the only element which is able to enhance the resistance to multiple stresses. “Silicon has been recognised in Japan as an agronomically essential element”.
