US Patent 8649942 System and method for controlling a material application system

An engine speed sensor determines engine speed data of an internal combustion engine for moving a material distribution vehicle. A ground speed sensor measures a ground speed of the material distribution vehicle. A data processor for controlling a dispensation system to distribute an agricultural input or material at a rate based on the measured ground speed and the engine speed data (e.g., sensed engine speed or change in engine speed) to anticipate a change in the ground speed of the material dispensation vehicle such that a lag in the rate of agricultural input delivered is reduced.
