In one aspect, a method for monitoring seed placement within the ground during the performance of a planting operation includes receiving, with a computing device, a timing signal associated with a detection of a seed to be deposited within soil by a row unit as the row unit is actively depositing seeds within the soil, and identifying, with the computing device, a time associated with when the seed will pass through a detection zone of a seed placement sensor supported relative to the row unit based on the timing signal, the seed placement sensor configured to detect the seed as planted underneath a surface of the soil. In addition, the method includes evaluating, with the computing device, data collected by the seed placement sensor during the identified time to determine a seed placement parameter associated with seed.

The planter system also includes a sensor configured to transmit a detection signal upon detection of the seed passing a detection location. The planter system also includes a control system configured to determine a travel time of the seed from the detection location to a furrow based on a baseline drop time for the seed, a baseline travel speed of the seeder assembly, and an operating travel speed of the seeder assembly. The control system is configured to transmit a control signal to a valve coupled to a nozzle assembly based on the travel time and the detection signal to spray the fluid on or adjacent the seed.

A plurality of different controllers on an agricultural machine are time synchronized. A first controller, identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, and generates a timestamp indicating a time at which the action is to be taken. An action identifier and the timestamp are sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the timestamp based upon the actuator delay.
