dc.description.abstractThe nature of ammonium released from 2:1 layer silicates with varying degrees of tetrahedral/octahedral isomorphous substitution has not yet been defined. This study investigated the influence of 2:1 clay charge caused by octahedral or tetrahedral sheet substitution on the amount of ammonium released. Twelve surface soil (0-30 cm) clays in Taiwan were examined. Deferrated clays with added ammonium fixed had -0.8 volts (V) current applied for 30 min to release ammonium from soil clay suspensions. The mean value of total ammonium released ranged from 0.72 to 3.66 cmol kg(-1). The percent of total ammonium released with respect to total ammonium fixed ranged from 5.81 to 83.22%. The added ammonium fixed plus the tetrahedral sheet contribution to ammonium fixed showed a correlation coefficient (r) of 0.797 with the amount of ammonium released.en_US
