Abstract
A laboratory experiment was carried out to investigate the effects of the additions of lime soluble starch on the behavior of silica in submerged soil. 1. Available silica in the submerged soil was increased as pH come up to neutral condition and Eh decreased. 2. Application of soluble starch accelerating the soil reduction nearly doubled the amount of silica sorbed in soil from silica solution. 3. Silica sorption of soil treated with slaked lime was increased to some extent in the low silica solution but was not showed that constancy in high silica solution. 4. The reaction between amount of silica sorbed in soil and silica concentration in solution followed not Lamgmuir but Freundlich adsorption isotherm.
