Organic Plant Growth Enhancer

What is CropSIL?

CropSil is the biologically active form of silica--orthosilicic acid (OSA). This molecule is the only form of silica that plants (or animals) utilize. It is termed 'biogenic' which means it is produced by living organisms. Biogenic silica exists as a single molecule (monomer) only when dissolved in water. It does not exist as a solid form. The silicates that make up 27% of the earth's crust are polymers of silica that are not available to plants.

Benefits of Silicon Nutrition

Potential benefits of sustainable silicon nutrition include:

  • Increase in photosynthesis

  • Chlorophyll production

  • Resistance to pathogens

  • Water use efficiency

  • Resistance to drought, salinity and metal toxicity

Silicon in Soils

All soil--sand, silt or clay--is derived mainly from silica. Biogenic silica exists naturally in all water sources in the same concentration. Its concentration in water is due to the slow dissolution of silicates native to soils. Adding silica to soil in any form does not increase this concentration. 

Because of its instability, biogenic silica condenses into silica aggregates (polymers) when the soil solution concentration exceeds 2 PPM. These aggregates form the basis of all soils and are biologically inert. Silicates applied to the surface of plants may have active characteristics such as insect repellency, but they do not elicit the biochemical responses of biogenic silica.

Benefits of Foliar Silicon Supplements


The scientifically proven effects of silicon nutrition are many. It is utilized in a range of cellular reactions necessary for plant growth.


All plants accumulate silica to some degree, but some plant families are known as silicon accumulators or hyperaccumulators. Because most plants have a high affinity for silicon, it is rapidly taken up and translocated from the soil. Because of this strong attraction, plants may exhaust the soil solution of silicon leading to deficiencies.

The patented formulation of CropSIL solves this problem by making OSA available to plants through applications to foliage. This method bypasses the soil which limits silicon availability.

Silicon represents 27% of the earth's crust and is the second most abundant element on earth.  However, silicon availability to plants is limited by its molecular structure.
