Seaweed Extract
Our seaweed extract is made from Kelp seaweed. Kelp seaweed is a kind of delicious sea food for Chinese, Korean and Japanese. Besides alginate acid, it contains luxuriant mannitol, iodine, gibberellin, CTK, indoleacetic acid and many necessary microelement for crops, for example, Fe, Mg, Mn, Zn, etc. In fact, Kelp seaweed is the best and most expensive raw material of seaweed fertilizer.
We produce seaweed fertilizer by biodegradation. We have gained IMO organic certificate, ISO: 9001 ISO:14001 certificate and other certificates used for production, environment protection and export. We do not add any chemical products or damage the active constituent of seaweed during the process and remain all the nutrients of Kelp seaweed. We do not extract any element, so all the nutrients of seaweed can be used in fertilizing the crop. We have been concentrate on fertilizer production for 7 years and continue our ideas in the future, this is the biggest advantage upon other seaweed fertilizer manufacturer from China.
