The invention provides a system, device and method that can control the rates of seed dispensation and fertilizer application as a function of forward speed as well as across all rows. Thus, the system and control device allow control of each individual row unit, whereby dispensation and application are effected, by a central controller which controls a plurality of pulse width modulation valves, each of which controls a hydraulic motor with an integrated rpm reduction and which drives a stub drive shaft which rotates at the proper speed in order to provide the desired seed and fertilizer metering. Each of the stub drive shafts may rotate at completely different speeds and/or may be shut down while the remaining stub drive shafts rotate at the desired speed. The integrated rpm reduction within each hydraulic motor allows very fine rotational control of the dispensation and application rates.
