Soluble Seaweed Extract Powder is a 100% fresh seaweed extract and naturally composed of nutrients, trace minerals, carbohydrates such as alginic acids and plant growth promoters. It will rapidly correct nutrient deficiencies, improve fruit set, help plants endure environmental stress and has antitoxins to fend off bacteria and viruses, and to repel insects. It is suitable for all crops and applications including field crops, potting soil, vegetable and flower gardens, orchards and turf grass.


3. Application:



Restrain and resist bacilli, Improve crop’s quality and nutritional value of plant, enhance resistance of crops, induce plants to enhance resistance 

to disease, balance nutrition


For example:Function and Effects in Agriculture


1) Improve plant anti-stress capability:

Stress in plants, as in animals, is a reaction to some kind of threat or environmental change and it generates a hormonal response. The hormones found in seaweed can have a huge impact on controlling or reducing that stress.

Stress can be linked to growth phases. Germination is the first stress period. Gibberellic acid is a proven germination promoter. A seaweed-based starter solution will enhance germination rates and reduce germination time. Lettuce seeds, for example, will germinate in the dark with gibberellic acid.

The switch from vegetative to the reproductive phase can also be stressful. A seaweed fertilizer spray prior to budburst has proven very productive. Gibberellins have been linked to the onset of flowering, while cytokinins have been linked to bud formation.

Drought and waterlogging are other common sources of stress. During periods of drought, the naturally occurring cytokinins, which govern the closing of stomata to reduce transpiration from the roots, are seriously decreased. The cytokinins found in seaweed help compensate for this shortage. Waterlogging also disrupts cytokinin translocation and, once again, a kelp supplement will be beneficial.


2)Enhanced Immune Response:

Anecdotal evidence, since the 1940s, has highlighted a link between growth regulators and immune response. Comprehensive experiments carried out in the 1960s, involving red spider mites in peaches and apples and aphids on strawberries, confirmed this link. The gibberellins in seaweed seemed to be the key.


3) Management of Nematode-Affected Soils:

There are three mechanisms at work here. Seaweed stimulates the proliferation of nematode-trapping fungi, and this biological management accounts for part of the response. Seaweed also contains several antibiotics, which may be playing a role and, once again, hormones are playing a role. Cytokinins, for example, have demonstrated a capacity to inhibit larval penetration of plant roots.


4)Frost Resistance:

Seaweed is a highly effective brix-builder. High-brix plants have a higher sugar content, which translates to a lower freezing point. A two to five degree frost protection has been recorded. Seaweed also contains abscissic acid and polyamino compounds, which have also been shown to protect crops from frost damage.


5) Increased Shelf-Life:

Experiments with peaches produced a 300% decrease in susceptibility to post-harvest rot for crops that had been foliar-sprayed with seaweed fertilizer twice before harvest. There also appears to be considerable potential for post-harvest dipping. A significant increase in the shelf-life of capsicums has been demonstrated following immersion in seaweed extract.
