As a professional seaweed fertilizer supplier, SEAWIN holds independent ocean resources. We have built three production bases in Jiaozhou Qingdao, Rushan Weihai and Rongcheng Weihai separately, which are all close to the seaside providing convenience for the harvesting of rich marine biological resources like green algae, kelp, oyster and byproducts of aquatic products. Rich raw material resources can not only guarantee output, but also reduce manufacturing costs, so that we can provide cheaper yet high quality seaweed fertilizer to customers.
Algae is found readily in Chinese coastal waters.
High reproducibility, high yield and abundance on rocks in the intertidal zone are three features of Algae. The natural algae yield is as high as 100 thousand tons just in Fujian coastal waters, thus leading to low cost algae cultivation and stable raw material supply.
Kelp is a type of large economical algae growing in low-temperature seawater and most often cultivated in northern coastal waters and Zhejiang, Fujian coastal water. The output of kelp in China ranks first in the world. Rongcheng city in Shandong province is called the “Hometown of Kelp in China” with annual output of more than 1000 thousand tons of kelp, accounting for 50% of total output in China. We have built one production base for processing of kelp in Rongcheng city, to ensure a stable source of fresh kelp.Read More
The oyster is an alkalescent, thus suitable for neutralizing the acidic soil and adjusting soil pH. The plentiful bio-calcium and micro parasite in oysters can regulate the microbial ecosystem in soil. At the same time, the special physical structure of oyster can absorb the heavy metals in soil.Read More
With rich aquatic products, the annual processing volume of cod is between 400-600 thousand tons. A large amount of fish skin is harvested, serving as sufficient raw materials for our production.
Fish skin contains abundant protein and amino acids, which are essential nutrients for plant growth. The glycine in fish skin can promote photosynthesis, increasing the content of chlorophyll and improving enzyme activity.
