Claim:
An agricultural implement for depositing particulate matter into soil, comprising: a drill having a plurality of soil engaging tools that are movable between a raised position and a lowered position, the soil engaging tools configured to be disengaged from the soil when in the raised position and configured to be engaged with the soil when in the lowered position; a satellite navigation system that maps movement of the implement when the soil engaging tools are in the lowered position and provides an output signal when the implement traverses a region of the soil that into which particulate matter has previously been deposited; and an alert that is activated when the satellite navigation system provides the output signal, the alert configured to notify an operator of the implement that the implement is traversing a region of the soil that has previously been deposited with particulate matter without automatically adjusting the deposition of the particulate matter into the region of the soil that has previously been deposited with particulate matter.
