Method and vehicle for applying an agrochemical mixture to a working area of a field

A vehicle for applying an agrochemical mixture to a working area of a field while moving on the field, the vehicle comprising:

• a solid fertilizer spreading device, mounted on the vehicle for spreading a solid fertilizer on the working area;
• and
• a field sprayer, which is mounted on the vehicle separately from the solid fertilizer spreading device, for spraying a liquid fertilizer additive on the working area,
• wherein the field sprayer is arranged relatively to the solid fertilizer spreading device so that the liquid fertilizer additive is prevented from coming into contact with surfaces of the solid fertilizer spreading device, which also come into contact with the solid fertilizer,
• wherein the solid fertilizer spreading device is arranged at a rear of the vehicle in a direction of travel and the field sprayer is arranged at a front of the vehicle in the direction of travel, and
• wherein the solid fertilizer spreading device and the field sprayer are configured such that the liquid fertilizer additive and the solid fertilizer are applied separately to the working area of the field.

A method for applying an agrochemical mixture to a working area of a field using a vehicle moving on the field, comprising:

• spreading a solid fertilizer on the working area using a solid fertilizer spreading device mounted on the vehicle;
• separately spreading a liquid fertilizer additive on the working area using a field spreader, mounted on the vehicle separately from the solid fertilizer spreading device;
• determining a geographical position of the vehicle;
• and
• applying a predetermined quantity of solid fertilizer and liquid fertilizer additive, respectively, to the field depending on the determined geographical position of the vehicle,
• wherein the solid fertilizer spreading device is arranged at a rear of the vehicle in a direction of travel and the field spreader is arranged at a front of the vehicle in the direction of travel.

A vehicle for applying an agrochemical mixture to a working area of a field while moving on the field, comprising:

• a solid fertilizer spreading device, mounted on the vehicle, for spreading a solid fertilizer on the working area;
• a field spreader, which is mounted on the vehicle separately from the solid fertilizer spreading device, for spreading a liquid fertilizer additive on the working area;
• a control unit that controls rates of spreading the solid fertilizer and the liquid fertilizer additive on the working area;
• and
• a geographical locating means coupled to the control unit,
• wherein said control unit is adapted to control the rates of spreading the solid fertilizer and the liquid fertilizer additive on the working area as a function of a geographical position of the vehicle,
• wherein the solid fertilizer spreading device is arranged at a rear of the vehicle in a direction of travel and the field spreader is arranged at a front of the vehicle in the direction of travel, and
• wherein the solid fertilizer spreading device and the field spreader are configured such that the liquid fertilizer additive and the solid fertilizer are applied separately to the working area of the field.
