1. A method for dispensing dry granular material from a moving agricultural implement, said implement having a main control unit and a plurality of sub-controllers, one for each of a plurality of dispensing mechanisms, each for dispensing dry granular material directly to a crop row, comprising the steps of:

  • determining a desired dispensing rate;

    generating command data consistent with the desired dispensing rate to control the actuation of a metering device in each said dispensing mechanism to dispense said dry granular material directly to said crop row;

    measuring the ground speed of the agricultural implement;

    modifying the command data to account for the ground speed at each dispensing mechanism;

    receiving stored calibration data for each said metering device from an electronic storage device;

    further modifying the modified command data to account for the calibration data of each said metering device; and

    actuating the metering device in response to the further modified command data.
