The importance of direct field measurements is underlined by the fact that spreading of pesticides is a terrible complex issue that is influenced by many variables, so that theoretical calculations are inherently not very accurate (Fantke, Jolliet, 2016).
A special problem in calculations on pesticide flows is the decay time of the product (depending of many
