This experiment was conducted to find out the minimum size of pores through that Zeolite particles moved vertically out with percolated solution in the sand column and to estimate whether they were lost through the pores in the field sandy soil. The results were as follows. 1. The amount of Zeolite loss through sand columns was increased in the order of the columns filled with $2{\sim}1>1{\sim}0.5>0.5>0.25mm$ sand particles. 2. The Zeolite particles lost through columns filled with $1{\sim}0.5$ and $0.5{\sim}0.25mm$ sand were clay fraction. 3. The pore sire that clay fraction of Zeolite mineral could migrate through was determined to be above $150{\mu}m$ and Jangchon subsoil was presumed to have possibility of Zeolite loss in consideration of its pore size distribution. 4. The suitable particle size of Zeolite for application in sandy soil was presumed to be above $2{\mu}m$.
