Although silica accounts for a significant ratio among the elements contained in soil, natural silica can’t be used by plants.

However, water-soluble silicates produced by the heat processing on silica have the remarkable ability to be absorbed into plants. 

Water-soluble silicate increases photosynthesis and harvests by forming a silica layer and inducing light scattering and improved crop quality.

Purification of soil: Water-soluble silicate inhibits the growth and propagation of harmful microorganisms in the soil with sterilization and purification ability. 

A silica layer (cuticle layer) is formed, and photosynthesis increases due to the light scattering effects. Then, the harvest will increase with improved crop quality (improvement of sugar content, color, scent, and quality for storage).

- Neutralization of acidic soil: Si-Star neutralizes acidic soil into neutral soil, which plants and crops like.
