What is Silicon?

Soil minerals on earth’s surface are the result of weathering of rocks over time. They contain approximately 47% oxygen, 28% silicon, 8% aluminium, and 5% iron. The remaining 90 over types of elements together constitute only 12% of the mass of soil minerals. Most of the soils contain minimal portion of silicon in the form of silicic acids (H4SiO4) and the intensive cropping can reduce the levels of soluble silicon to the extent where "supplemental silicon nutrients" is gravely needed for crop’s yield production and pests’ protection.

Majority of the low silicon soils are highly weathered, leached, acidic and low in base saturation. The silicon in sand, silt, and clay is extremely insoluble and difficult to be absorbed by plant. Organic soils that contain little mineral matter may also contain little silicon, and soils comprised mainly of quartz sand are also inadequate in plant available silicon.

Although NPK fertilizers supply all the main nutrients in plants, silicon fertilizer is an important element to restore major soil deficiencies. Long period of intensive crops cultivation depletes the available soil silicon, while NPK loss, are restored by fertilization, silicon application is usually ignored in the past.

Silicon-based fertilizers (H4SiO4) are already being well recognized and highly researched in China, Japan, Korea, Thailand, Australia, Russia, Canada and Brazil and it is categorized as a supplementary fertilizer and classified as beneficial to crops in few major agriculture countries.

This "amazing mineral" enabled some of the silicon producing countries to achieve such excellent growth in their agriculture sectors.
