For effective uptake, fulvic acids are organic compounds usually derived from deposits of ancient decomposed organic material.

Along with humic acids, they are often found within or near deposits of lignite (brown coal) or leonardite (weathered brown coal).
As they have been formed through long processes of natural decomposition from a range of substances they are comprised of groups of organic molecules as opposed to a single compound.
They contain a high carbon content. Fulvic substances are therefore natural in origin and have been found to be beneficial to plants.
These benefits include root stimulation, increased leaf chlorophyl content and increased productivity and yield.
The small molecular structure of fulvic acids allows them to be easily absorbed by plant leaf surfaces.
Fulvic acids are recognised as natural chelators. Chelating agents are attracted to, and protect, elements from being chemically bound to each other (for example, phosphorous and iron). Fulvic acids are also highly water soluble.
These combined attributes of ready uptake by the leaf surface and an ability to chelate make fulvic acid a natural partner for foliar nutrient applications.
Fulvic acids are lightly coloured, compared to humic acids, making fulvic acids unlikely to stain when applied over foliage.
Fulvic acids can also be successfully applied to soil but typically the larger humic acid substances used for applications to soil.
Convenient to use liquid formulations of fulvic and humic acids are obtained by processing the raw resource to obtain a uniform product. The refined filtered liquid is without impurities that may exist in the raw material.
Seasol’s Trilogy fulvic acid product is organically certified and combined with kelp (Seasol), for root growth and increased tolerance to plant stress, plus PowerFish providing amino acids beneficial to plants creates an easy method of foliar application.
