The predecessor of SHIDAI MARINE was established in 1968, when it was engaged in kelp farming for China's iodine industry. In 2010,SHIDA MAIRNE entered the agricultural industry and established a professional kelp enzyme hydrolysis liquid fertilizer production enterprise with a registered capital of 53.12 million yuan, a total investment of 280 million yuan, a construction area of 32000 square meters, and more than 300 sets of production equipment, including 80% of independent innovation equipment. It has the production capacity of 100000 tons of fresh kelp enzyme hydrolysis slurry annually. Nowadays, SHIDAI MARINE has grown into a global crop nutrition solution company. SHIDAI MARINE operates through the kelp industry and integrated business models, with businesses spread across dozens of countries in Asia, Europe, the Americas, and Africa, gradually becoming an internationally renowned seaweed production enterprise.

Ten thousand acres of fresh kelp aquaculture resources of SHIDAI MARINE

In the Chengshantou sea area, which is the most suitable for kelp growth in the world - at the junction of 37.39 degrees north latitude and the Yellow Ocean Current, SHIDAI MARINE has 15000 acres of independent marine ecological breeding base, which can produce more than 200000 tons of fresh kelp annually. From May to August, SHIDAI MARINE will enzyme hydrolyze freshly harvested kelp to preserve its natural active substances to the maximum extent possible, obtaining the highest content of natural and organic active ingredients in kelp enzymatic hydrolysate. Every year, tens of thousands of tons of kelp pulp are transported to various parts of the world, contributing to the quality agriculture of the world.

Continuous advantages in the industrial chain, providing more precise solutions

SHIDAI MARINE have the entire industry chain of kelp, from kelp breeding, to kelp enzymatic pulp, to fertilizer preparations and their own orchards. We have production and application experience in all aspects of the entire industry chain, from the source of seaweed to the export of agricultural and sideline products, which enables us to better serve customers from various nodes.

Blue oceans feed back green agriculture, and land and sea coordinate the ecological cycle

The use of fertilizers has greatly helped China solve the food problem of 1.4 billion people, but the loss of nutrients from fertilizers should not be underestimated. A large amount of nutrients are collected into the ocean through surface and underground circulation, resulting in an abundance of nutrients between the oceans. SHIDAI MARINE extract fresh kelp harvested each year through enzymatic hydrolysis technology to produce natural biostimulants from kelp sources, which are applied in green and organic agriculture fields to enhance crop immunity, increase yield, improve quality, and reduce fertilizer usage by 20-25%, thus forming a land sea coordinated ecological cycle where the blue ocean nurtures green agriculture.
