PURPOSE:To obtain an acidification inhibitor, composed of powder consisting essentially of calcium silicate hydrate and capable of preventing soil from acidifying in districts where acid rain falls simply by spraying thereof on soil and holding metallic elements indispensable to growth of plants in the soil. CONSTITUTION:The objective acidification inhibitor composed of powder consisting essentially of calcium silicate hydrate, composed of tobermorite, xonotilte, gyrolite, etc., and expressed by the composition formula of xCaO.ySiO2.zH2O (x is 2-6; y is 1-6; z is 1-9) at <=1.5 composition element ratio Ca/Si thereof. |
