Pedotransfer functions as a tool for estimation of pesticides behavior in soils

Popis výsledku v původním jazyce

Soil Informatics, a new discipline makes possible to interpret the results of research in a new way. Possiblity for interpretation of adsorption characteristics of atrazine in soils of the CR was studied. Our approach was based on exploitation of pedotransfer functions. As a pedotransfer function we used multivariate statistical methods. Kd value for atrazine estimation was based on the konwledge of data on humus content, soil texture pH and CEC values, respectively. The results were interpreted in theGIS environment exploiting the digitized soil map of the CR at scale 1: 200 000 and the corresponding database of soil characteristics. The spatial distribution of Kd values for the topsoil and the subsoil were computed and presented as soil vulnerability maps. The results have shown that there was a substantial decrease in Kd values in subsoil. For better assessment of that decrease the ratio of Kd values for atrazine in topsoil and in subsoil was coputed. Under the filed conditions it
