Proprietary Technologies

Enzymatic Extraction

Seawin's highly technical and specialized multistep enzymatic degradation process maintains high levels of active ingredients versus a chemical extraction method.The process generates a wider variety of differentiated polysaccharides in the product enhancing the overall performance in crop production.

Molecular Screening

This proprietary Seawin IP technology has the following benefits: -Enhances the development of new homogeneous products. -Allows for superior tank mixing capacity, -Provides consistent, smaller molecular products providing greater plant uptake, Can provide molecular screening that enhances the mineral chelating ability of the products.

Biological Chelating  Technology

Seaweed polysaccharide sulfate extracted by Seawin is an effective alternative to EDTA chelation and proven to boost utilization of trace elements.

Unique Features

Seaweed Polysaccharide

Seawin's polysaccharide is a natural chelating agent and soil buffering agent, which improves nutrient availability to plants. The naturally occurring growth promoting factor also enhance plant growth and help plants to cope with stresses.

Fish Protein

Extracted from the cod fish skin using Seawin's highly technical enzymatic degrading process. This provides high level of organic soluble nitrogen (Amino Acid), also a significant amounts of growth hormones such as Cytokinin,  which enhances crop's anti-stress abilities.



Bacillus subtilis is able to make more nutrient available to plants, improve overall soil health and it is able to help to suppress bad pathogens in the soil/growing media. It is derived from extreme conditions or from the rhizosphere, making it able to colonise in a range of environments.
