A method for applying an agrochemical mixture to a working area of a field using a vehicle moving on the field is described. Thereby, a solid fertilizer is spread on the working area using a fertilizer spreading device mounted on the vehicle and a liquid fertilizer additive is sprayed on the working area using a field sprayer, mounted on the vehicle separately from the fertilizer spreading device. Therein, the liquid fertilizer additive is prevented from coming into contact with surfaces of the fertilizer spreading device, which also come into contact with the solid fertilizer. Moreover, a vehicle for applying an agrochemical mixture to a working area of a field while moving on the field is also described.
