In this study the mathematical model CMLS (Chemical Movement in Layered Soils Model; Nofziger & Hornsby, 1994) has been applied to quantify the amount of selected herbicides present at the bottom of the vadose zone so as to estimate pesticide transport and degradation in the soil. CMLS model results have been integrated into a geographic information system (GIS) by means of raster techniques to produce maps of leaching potential for several herbicides under different management practices. Integrated use of GIS and pre-vision models can be considered as a powerful tool to support decisions. The selected area, about 30 km(2), is located in the Lombardy Po plain (Italy)

Abstract
In this study the mathematical model CMLS (Chemical Movement in Layered Soils Model; Nofziger & Hornsby, 1994) has been applied to quantify the amount of selected herbicides present at the bottom of the vadose zone so as to estimate pesticide transport and degradation in the soil. CMLS model results have been integrated into a geographic information system (GIS) by means of raster techniques to produce maps of leaching potential for several herbicides under different management practices. Integrated use of GIS and pre-vision models can be considered as a powerful tool to support decisions. The selected area, about 30 km(2), is located in the Lombardy Po plain (Italy)
