This experiment was conducted to evaluate the soil spplication effects of natural and lime fertilizer of oyster shell on physicochemical properties of soil and the growth of 'Campbell Early' grapevine. The natural oyster shell contained 450.6 gㆍkg-¹ of alkalinity, 449 gㆍkg-¹ CaO, 1.6 gㆍkg-¹ MgO, 0.38 gㆍkg-¹ SiO₂ and 1.3 gㆍkg-¹ salt, and was not greatly different from the processed powder of oyster shell. The pH and Ca content of soil were higher in natural oyster shell, Ca(OH)₂, and CaCO₃ㆍMgCO₃ fertilizer treatment to soil than those of the control.
