The research laboratory Ecosistemi, for the areas of applied pedology and environmental controls, adopted, after several tests, the OECD/OCDE 312 Leaching in soil columns method

The analytical simulation procedure, for the study of the leaching of added components in the soil and for the analysis of the mobility of pollutants in the soil, has been widely tested its operational application in controls and analysis in the experimental and industrial field.

The method, applied for a specific research on a specific type of fertilizer, is extremely useful and interesting for the examination of a wide range of chemicals and materials that can be put in contact with the terrestrial environment. The test method is based on chromatography on a disturbed soil column and the leaching potential of a substance and the leaching potential of transformation products in soils under controlled laboratory conditions can be determined.
