Seaweed —— The Gift from the Ocean


Fertilizers are added to crops in order to produce enough food to feed the human population. Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and produce more food.

And seaweed is one of the oldest fertilizer varieties, its use as fertilizer can be dated back to the 4th century AD. Seaweed fertilizer can not only provide necessary nutrients and trace elements for crops but also regulate the healthy growth of crops, improve resistance and improve the overall performance of crops through the natural bio stimulants and stress tolerance factors contained in the seaweed.

What are Seaweed Fertilizers?

Unlike most other traditional fertilizers, Seaweed fertilizers are organic plant feeds containing extracts of seaweed sustainably derived from the ocean, they contain naturally occurring growth stimulants for increasing crop yields that often can’t be found elsewhere.

  • Not only increase crop yield, but Seaweed fertilizers also improve plant health through resistance to stress, disease, illness, and pests.

  • Fruits and vegetables grown with Seaweed fertilizers benefit from longer life after maturity.

Ascophyllum nodosum - Gift from Atlantic

The main raw materials of King’s Landing Seaweed Oligose is Ascophyllum nodosum originate from the North Atlantic.

Ascophyllum nodosum is a species of seaweed that grows in the intertidal zone of the Northern Hemisphere, the stressful conditions of repeated exposure to desiccation, ultraviolet light, and temperature fluctuations experienced by the seaweed in this habitat, Ascophyllum nodosum is naturally resistant to stress in a certain. A slower growth rate leads to the high concentrations of bioactive compounds.

Bioactive in Ascophyllum nodosum including Seaweed polysaccharide, Mannitol, Iodine, Alginic acid, Betaine, Amino acids, and some rare trace elements.


Seaweed Oligosaccharide?

Oligosaccharide is a naturally derived oligosaccharide from brown seaweed. As a kind of endogenous plant - like oligosaccharides, algae oligosaccharides play the role of signal molecules in plant stress resistance and can promote plant growth. Soaking seed with the seaweed oligosaccharides increases the germination rate of seeds, seedling height, root length, the chlorophyll content in the leaves of the seedlings, the root vitality, and yield. It is a stimulant for plant growth and development.

The Effect of Seaweed Oligosaccharide on Plants

  • It can promote root growth and seed establishment.

  • Enhance plant resistance and drought resistance, and induce crop resistance through signal factors. After use, the crop will show obvious tolerance when facing the harsh external environment, and the resistance effect is obvious.

  • Inhibit plant pathogenic bacteria, induce plant defense response, and then produce systemic resistance to make plants have disease resistance.

  • It can be used as a stabilizer for pesticides, as an insecticide, fertilizer forming agent, regulator, etc.


The Synergistic Effect of Seaweed Oligosaccharides in Nitrogen Fertilizer

The complex, ion-exchangeable, and slow-controlling properties of the special carboxyl group in the oligosaccharide structure can be combined with the cationic groups in nitrogen fertilizers to slowly release the active factor ammonium ions in nitrogen fertilizers in the soil, so as to achieve long-term nutrient supply for plants. It can also improve the utilization rate of nitrogen fertilizer to a certain extent.
