Abstract

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.

sensing engine speed data of an internal combustion engine for moving a material distribution vehicle;

measuring a ground speed of the material distribution vehicle; and

controlling, a dispensation system to distribute an agricultural input or material at a distribution rate based on the measured ground speed and the sensed engine speed data to anticipate a change in the ground speed of the material distribution vehicle from interpretation, by a data processor, of an operator input prior to reaching a new ground speed such that a lag in the distribution rate of the agricultural input delivered is reduced.

2. The method according to claim 1 wherein the sensing of the engine speed data comprises sensing a change in an engine speed of the internal combustion engine.

7. The method according to claim 1 further comprising:

determining a position of the material distribution vehicle via location-determining receiver;

storing prescription data comprising the position of the vehicle versus the distribution rate for the agricultural input to be dispensed via the dispensation system, and

adjusting the distribution rate based on the position of the material distribution vehicle, the prescription data, the measured ground speed and the sensed engine speed data to anticipate a change in the ground speed of the material distribution vehicle such that a lag in the distribution rate of agricultural input delivered is reduced.
