Abstract: A method is for training a neural network for determining features of objects for object tracking. The method includes generating a training dataset with a plurality of training data elements. Each training data element has a first set of sensor data relating to a first state of an environment with a set of a plurality of objects and a second set of sensor data relating to a second state of the environment. In the second state, the positions of the objects have at least partially changed compared to the first state. The method also includes determining features of the objects by feeding the first set of sensor data to the neural network and determining features of the objects by feeding the second set of sensor data to the neural network. A loss is determined depending on the generated features, and the neural network is trained to reduce the loss.

Abstract: A method for dispensing at least one liquid medium with the aid of a spray nozzle unit, in particular for agricultural purposes. The spray nozzle unit includes at least one spray nozzle via which the medium is dispensed, and at least one sensor device via which a biomass, in particular weeds, is/are recognized. With knowledge of the location of the biomass, the at least one spray nozzle is activated in order to dispense the medium onto the biomass.

Abstract: A method for applying a spray to a field using an agricultural spraying device. The method includes: monitoring a field section of the field having plants, using an optical and/or infrared detection unit; identifying at least one row of plants in the monitored field section using a processing unit; using the processing unit, defining a plant region including the at least one identified row of plants in a specified evaluation portion of the monitored field section, using the at least one identified row of plants and a weed region different from the plant region; ascertaining a plant value of the weed region in the specified evaluation portion of the monitored field section using the processing unit; and applying the spray to the weed region of the specified evaluation portion as a function of the ascertained plant value, using spray nozzles of the agricultural spraying device.

Abstract: A fertilizing system for agricultural soils includes an application device for applying fertilizer and including a test device for detecting a nitrous oxide content in or on the agricultural soil to be fertilized. The test device includes multiple nitrous oxide sensors including in each case a first transmission device for transmitting measuring data, and including a data processing device that includes a first receiving device for receiving the measuring data.

Abstract: The disclosure relates to a device of a vehicle, in particular a tractor, having a hydraulic activation unit for controlling the operation of a towed implement on the vehicle, comprising at least one position detection unit with at least one camera, position detection marks, and an evaluation unit and a data-transmitting connection to a control unit which is assigned to the hydraulic activation unit. Furthermore, a method is proposed, wherein by means of such a position detection unit the position of the towed implement can be determined, and the position can be adjusted according to requirements by suitable operation of the hydraulic activation unit.
