Abstract:

The use of pesticides and their potentially negative effects on the environment are currently widely debated. However, it is difficult to imagine sufficient food production completely without their use; therefore, more attention has to be given to managing their use by considering site-specific spatial environmental data. In this study, the use of the FOOT-CRS (Footprint-Catchment Scale) tool, which was developed in the European project: “Functional tools for pesticide risk assessment and management”, is presented on a model location in the Apače Valley, Slovenia.The results clearly showed that the potential negative impacts of selected pesticides can be foreseen in advance; therefore, the pesticide usage can be adjusted accordingly to environmental and spatial characteristics of a given catchment. Pesticide leaching risk assessment on the catchment scale strongly depends on input spatial data quality. A soil map in the scale of 1:25,000 does not sufficiently cover the variability of soil properties; therefore, pedological data should be supplemented on a larger scale, with the final aim of knowing basic soil properties on the field level.
