The amounts of piperophos adsorbed on various type of soils, clay minerals and organic substances were estimated. Soils containing montmorillonite adsorbed larger amount of piperophos than those containing kaolinite, mica and allophane. The order of adsorption was humic acids>montmorillonite>halloysite>kaolinite>allophane. Peatmoss, lignin and compost also adsorbed a large amount of piperophos. Both clay minerals and organic matter were effective adsorbents for piperophos and the properties of these colloids influenced adsorption of the herbicide. The removal of organic matter of soils by hydrogen peroxide oxidation decreased the adsorption in the soils containing kaolinite, mica and allophane, but increased that in soils containing montmorillonite. In the case of soils containing low adsorptive clay minerals (kaolinite, allophane), the amount of piperophos adsorbed was highly correlated with clay and total carbon contents on a multiple regression equation. However, there were no correlations for soils containing highly adsorptive clay mineral (montmorillonite).
