Abstract
A fertilizer system that employs an independent hydraulic motor and variable speed pump to deliver the selected application rate from the convenience of the operator's cab. The application rate can be changed while planting without changing seed population and the application rate can be controlled sectionally as well. The system may additionally be used in combination with more sophisticated multi-functional control systems that read maps and use GPS technology to control the entire preparation and planting operation.
