FertiGold is derived from the green seaweed Enteromorpha Prolifera using a patented multi-step enzymatic extraction method, which preserves a great amount of active ingredients. It is also the only method that guarantees consistency and high quality of the active ingredients like green seaweed polysaccharides, amino acids, green alga protein, plant growth hormones and secondary & trace elements. The benefits of these active ingredients combined make this product an essential part of any fertigation program.

Seawin's Polysaccharide:

With Seawin’s unique extraction method, Seawin’s polysaccharide acts as a natural chelating agent and buffering agent, making nutrients more available to plants and better PH environment for nutrient uptake. The well preserved active ingredients also trigger plants to produce its own endogenous growth hormones, increase production of chlorophylls and improve plants’ metabolism, which then leads to better root & shoot growth, and better yield and quality.

Seawin’s polysaccharide, Alginic acid in particular, promotes the generation of reactive oxygen species under stress, which interact with protective enzymes to improve plants tolerance to environmental stresses. In terms of soil health, the unique chelating feature of Seawin’s polysaccharide promotes soil aggregate structure, improves soil heallth over time.
