Sodium alginate is a gummy substance derived from the cell walls of brown algae.

The chemical alginate is extracted by treating the seaweed with an acidic solution.

This is followed by another treatment with an alkaline solution such as sodium hydroxide. The resulting mixture is filtered and processed further until a clear solution containing alginate remains.Next, calcium salts are added, causing the dissolved alginate to become insoluble and drop out of solution.Finally the alginate is treated with sodium carbonate to form sodium alginate.Chemical Properties

Sodium alginate is a polymer composed of a repeating chain of the carbohydrates D-mannuronic and L-guluronic acid.

The properties of sodium alginate vary according to the length of the polymer.

It is an odorless, white to yellowish brown that can look fibrous, grainy or granular or like a dry powder.

Sodium alginate dissolved in water forms a thick and relatively slow-pouring liquid solution.

Seaweed fertilizer is made from seaweed and then add other element like Ferrum,Boron etc.At present,the product mainly appear three types:liquid,solid,and granula(take a small part).

Because algae has strong absorbility,the internal nutrition is very full.It's fit to become main raw material of fertilizer.


It not only apply to animal,plant but  to sea food ,soil.The best property is environmental,and no harm to human/animal/plant,at the same time,it could change quality of soil,making the microbe more active,unite the system of soil in order to give plant more nutrient.
