The invention relates to a system for co-ordinated soil cultivation, said system comprising a plurality of soil compacting devices (W1, W2) used to determine location-related relative compacting values (V(W1; TB1, xi, yi;I−1 . . . n)), and a calibrating device (EV) used to determine location-related absolute compacting values. A calculating unit (R), which is connected to the compacting devices (W1, W2) and the calibrating device (EV) in such a way as to transmit messages, is used to correlate the obtained relative and absolute location-related compacting values. A system control (CPU1, . . . , CPU4) is embodied in such a way that the location-related relative compacting values of the compacting devices (W1, W2) and the location-related absolute compacting values are transmitted to the calculating unit (R) in a continuous manner, stored therein, and in the event of the presence of compacting values in the same location, compacting correlation values are calculated and transmitted to the compacting devices where they are stored as correction values.
