Silicia & Sunprotection

Strong and healthy plants due to silicic acid (silicon) and sun protection from drying out.

Rice husks have several advantages that make them an attractive option for horticulture:

  1. Water retention: rice husks act as a mulch layer and help retain soil moisture. They form a barrier against evaporation and reduce the water needs of plants. This allows water to be used more efficiently and reduces the frequency of irrigation.
  2. Weed suppression: the layer of rice husks prevents weeds from sprouting. It covers the soil and blocks the sunlight that weeds need to grow. This reduces the need for manual weeding or the use of chemical weed killers.
  3. Nutrient supply: rice husks have a high silicon content, which is gradually released into the soil as they decompose. Silicon is important for plant growth and strengthens the cell structure, which can lead to more resistant plants.
  4. Soil improvement: rice husks promote soil structure and permeability. They loosen the soil, improve its aeration and promote the growth of microorganisms. The decomposition of rice husks introduces organic substances into the soil that can improve its fertility in the long term

The percentage amount of minerals in rice husks may vary slightly, but here are approximate averages:

  • Silicon dioxide (SiO2): about 90-95%.
  • Potassium (K): about 0.5-1.5
  • Calcium (Ca): about 0.2-0.5%
  • Magnesium (Mg): about 0.2-0.4%
  • Phosphorus (P): about 0.1-0.3%

Please note that these values are general estimates and may vary slightly depending on rice variety and other factors. We are happy to provide you with a lab report, we update it with each batch.
