1. A planting machine comprising:
a furrow opener configured to open a furrow as the planting machine moves across a field;
a seed delivery system configured to deliver seeds to seed positions in the furrow;
a granular material delivery system controllable to discontinuously apply a granular material, different than the seeds, to the field, the granular material delivery system comprising an inlet end configured to receive the granular material, an outlet end coupled to the seed delivery system, and a conduit disposed between the inlet end and the outlet end;
an actuation identification system configured to generate an actuation timing indicator indicative of a timing for actuating the material delivery system to apply the granular material at material placement positions relative to the seed positions;
a control signal generator configured to receive the actuation timing indicator and to generate an actuation signal based on the actuation timing indicator to control the material delivery system to apply the granular material to the field.
