Abundant oyster shell resources

The company is located in Rongcheng, which is the country's major oyster shell export land;

Rongcheng oyster shell is famous for its thick, fine powder and excellent quality, so our raw material are unique;

The company has developed into Chinese largest marine biological soil conditioner and marine biological fertilizer R & D and production enterprises.

Advanced technology

After 3 years of maturity, seawater salinity is degraded, and become marine organic matter;

Unique suitable temperature drainage and calcination technology to fill the gaps in china;

The company has become the country's largest oyster shell fermentation, high temperature oxygen activation and processing base.

Soil acid regulation

Biological acid neutralizing agents that completely abandon chemical products;

Nanometer calcium carbonate was small, high fertility;

Porous honeycomb structure makes water retention performance Lifting 3 times.

Soil improvement, with no side effects.

Crop calcium supplement

The organic calcium formed by the metabolites of natural oyster has high activity and is easy to absorb by the crops;

Oyster shell soil conditioner has calcium content as high as 46%, which is highly active biological organic calcium;

It is also rich in zinc, silicon, magnesium, boron, chitin, chitosan, protein, seaweed, amino oligosaccharides and other active substances and titanium, bismuth and other rare earth elements.

       Shandong Dibao Soil Remediation Technology Co. Ltd. is the first soil conditioner company registered in China. The company mainly uses oyster shell as main raw material and introduces technologies from Korea and Japan to produce soil conditioners.
       The company is located in Rongcheng, Weihai city. As oyster is local important marine economic species, Rongcheng, Weihai city is the main export area for oyster shell nationwide. With cultivated area of nearly 50,000 mu and 200,000 tons of annual output, it is very convenient to collect oyster shell raw materials.
       The oyster shells used by the company to produce oyster shell soil conditioner are ostreidae, Crassostrea plicatula, pacific oyster and Ostrea talienwhanensis Crosse. Oyster shell is big and thick and oyster shell powder contains more than 90% of calcium carbonate, calcium phosphate and calcium sulfate as well as more than 20 trace elements such as magnesium, sodium, strontium, iron, aluminum, silicon, titanium, manganese, barium, copper, zinc, potassium, phosphorus, chromium and nickel, and protein. Hydrolyzate contains 17 amino acids such as aspartic acid; glycine, glutamic acid, cystine and ethionine and total amino acid content is 0.15-0.24%.
       The oyster shells attached with a large number of algae, diatoms and marine plankton will go through aging fermentation process for a period of 3 years. After 3 years of maturity, the sea salt is degraded into marine organic nutrients, and then after separation and calcination, it becomes soil conditioners which can be directly used.
       Main raw materials for oyster shell soil conditioner are marine cultivated oyster shells. After aging fermentation of oyster shells and a large number of algae end plankton, raw materials are organics end processing process uses bio-engineering technology without any chemical products and so they are 100% biological organic products.
