Product Introduction

Our seaweed root fertilizer 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 microelements 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 ISO: 9001, ISO:14001 certificates and other certificates used for production, environmental protection, and export. We do not add any chemical products or damage the active constituent of seaweed during the process and retain 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.
