Amorphous Silica

Improve broadacre crop yields and quality

Carbon Ag’s amorphous silica is a natural fertiliser and soil conditioner made from the mineral amorphous silicon.  It provides crops with a rich source of plant available silicon, a bioactive nutrient that plays an important role in a range of plant functions, particularly when the crop is under stress. 

It is particularly effective in reducing the impact of drought and frost induced stress, as well as improving plants’ natural defence responses to pathogens and pests.

Carbon Ag’s amorphous silica granule product also is further enhanced by the use of proven coating technology from Crommelin AgriCoatings. The coating establishes a space in the immediate vicinity of the amorphous silica granule that strongly encourages microbial activity and ensures nutrient availability to the root zone.

Silicon is recognised as a beneficial bioactive plant nutrient, playing an important role in a range of plant functions.

Many soils and products contain high levels of sand (crystalline Silica SiO2) and clays (silicates) which are not in a form that can be utilised by plants. 

Silicon must be present as monosilicic acid, also known as Plant Available Silicon (PAS), before plant roots can absorb it. Carbon Ag’s amorphous silica contains 26% silicon that, in the presence of soil moisture, converts quickly to usable PAS.

Other important features 

• Amorphous silica has a high Cation Exchange Capacity, which reduces leaching of important plant nutrients, making them available for crop growth. 

• Amorphous silica has a high surface area and porosity, which enables it to retain water and release it when the soil profile dries out. 90% of this water is available to the plant.
