Abstract: Different aspects of the disclosure relate to a device and a method for agricultural soil cultivation with the aid of a soil cultivation unit. The method can include, for example: ascertaining an actual soil cultivation result in a soil cultivation area cultivated with the aid of the soil cultivation unit; ascertaining a deviation of the actual soil cultivation result from a setpoint soil cultivation result; and reducing a deviation of the actual soil cultivation result from the setpoint soil cultivation result with the aid of an adaptation of a rotational speed of a rotatably mounted soil cultivation tool.

Abstract: The invention relates to a soil-cultivation unit, comprised of a tractor (21) and a driven soil-cultivation machine or comprised of a tractor (21) and a passive, pulled soil-cultivation device (22) for conservation-type soil cultivation, having an equipment carrier with cultivator tools for accommodating one or more cultivator tines (6), characterized in that a regulation unit (23) is provided that accesses data that is recordable before and after travel over the work area in the work process and during the work process, control elements (10) are provided, via which the cutting geometry of the cultivator tines (6) can be adjusted, the regulation unit (23) is set up in such a way that control variables can be generated from the recorded data for setting the cutting geometry during the work process, and the cutting geometry of the cultivator tines (6) is can be permanently adjusted during the work process as a result of the control variables that are generated.
