Method for operating an agricultural spreader and an arrangement for an agricultural spreader system

A method for operating an agricultural spreader, comprising:

• providing a spreading material in a material reservoir of an agricultural spreader;
• dosing the spreading material from the material reservoir through a dosing opening formed in a wall element of a bottom wall of the material reservoir through which the spreading material is directly discharged from the material reservoir to a spreader device configured to receive and spread the dosed spreading material;
• receiving the dosed spreading material by the spreader device;
• spreading the dosed spreading material by the spreader device;
• detecting digital image data by a monitoring device, the digital image data being indicative of a partial quantity of the spreading material located in a lower half of the material reservoir in proximity to the dosing opening at the time of detecting the digital image data, wherein the monitoring device is located above the dosing opening;
• and
• determining a material parameter for the partial quantity of the spreading material located in the material reservoir in proximity to the dosing opening and being about to be dosed through the dosing opening from analyzing the digital image data by a control device.
