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.

We have built a production base in Rushan Weihai, where oyster cultivation is the characteristic industry with the annual output of many tons of oysters. The processed oysters can be used as soil conditioner.
