Soil properties affecting pesticide leaching - application in groundwater vulnerability mapping in the Czech Republic

Popis výsledku v původním jazyce

Various pesticide and soil properties affect pesticide leaching into groundwater. In order to assess the risk of pesticide leaching, specific groundwater vulnerability maps were constructed for selected pesticides based on modified DRASTIC methodology with emphasis on soil cover. The Freundlich equation was used to fit experimental data points of the adsorption isotherms for each pesticide and soil. The multiple linear regressions were used to define pedotransfer rules to determine the KF parameter fromthe other physico-chemical soil properties. Resulting pedotransfer rules were applied for the estimation of the adsorption properties of czech soils. The adsorption parameters KF represents only one soil factor affecting the contaminant transport through the soil cover. The properties of selected pesticides represent wide range of pesticides from those with none leaching potential to those with very good leaching potential. Specific groundwater vulnerability maps reflect those propertie
