Computer-implemented method for applying a product on an agricultural field

A system for applying a product on an agricultural field, the system comprising:

• a receiving unit configured to receive a control signal to start a continuous adaptation of a product rate and/or a frequency during a current application of the product on the agricultural field;
• a first determining unit configured to continuously determine a current amount of the product in a tank of an application device for applying the product;
• a second determining unit configured to continuously determine a current position of the application device in a route through the agricultural field;
• and
• an adapting unit configured to continuously adapt the product rate and/or the frequency based on the current position of the application device in the route through the agricultural field and the current amount of the product in the tank of the application device such that at the end of the route of the application device through the agricultural field a predetermined amount of the product is in the tank.
