Abstract
We studied on the bond between the inorganic colloid (Kaolin, Japanese acid clay etc.) and orgatnic soil colloid (Humus) by the method of colloid itration and electrophoresis. 1) Humus acted as a protective colloid for the clay minerals. 2) Humus had the greater equivalent per gram in the lower concentration, between 0.0225% to 0.0045%.
