Method for matching the operation of an individualizing device and the operation of a portioning device to each other

A method for matching the operation of an individualizing device and the operation of a portioning device of an agricultural dispensing machine to each other in order to achieve a specified local depositing relationship when depositing seeds individualized by the individualizing device and fertilizer portions produced by the portioning device on a usable agricultural area, the method comprising:

• depositing individualized seeds and produced fertilizer portions onto the usable agricultural area using the agricultural dispensing machine as part of a calibration drive;
• and
• detecting the depositing positions of the seeds and fertilizer portions deposited during the calibration drive and/or the local depositing relationship thereof using a mobile testing device;
• wherein a control system that is connected in a signal-conducting manner to the individualizing device and/or portioning device provides an operating behavior at least temporarily for the individualizing device and/or portioning device to achieve the specified local depositing relationship of seeds and fertilizer portions, the operating behavior determined by the control system on the basis of the depositing positions of the seeds and fertilizer portions detected by means of the testing device and/or on the basis of the local depositing relationship thereof, and wherein:
• the mobile testing device comprises an electronic measuring wheel and an actuator, wherein the measuring wheel is moved along a depositing path by an operator and the depositing positions of the seeds and fertilizer portions and/or the local depositing relationship thereof are detected by manual actuation of the actuator, or
• the mobile testing device comprises an electronic image recording device, wherein the depositing positions of the seeds and fertilizer portions deposited during the calibration drive and/or the local depositing relationship thereof are detected by evaluating one or more images of the seeds and fertilizer portions deposited during the calibration drive and recorded by the mobile testing device.
