1. An agricultural implement system, comprising:
a row unit coupled to a tool bar of an agricultural implement;
an opener system coupled to the row unit and configured to open a seed trench in a soil surface as the row unit travels in a forward direction of travel;
a seed delivery mechanism disposed rearward of the opener system and configured to deposit seed into the open seed trench as the row unit travels in the forward direction of travel;
a closing system disposed rearward of the seed delivery mechanism, configured to close the open seed trench with soil the closing system including:
a first closing wheel configured to move the soil adjacent a first side of the open seed trench into the open seed trench;
a second closing wheel configured to move the soil adjacent a second side of the open seed trench into the open seed trench;
a trench closing sensor disposed in the seed trench rearward of the seed delivery mechanism and extending toward the closing system, the trench closing sensor configured to generate a signal indicative of a force against the trench closing sensor applied by the soil moved into the seed trench by the first and second closing wheels; and
a controller in signal communication with the trench closing sensor, wherein the controller is configured to control a closing wheel actuator to adjust a downforce applied by the closing wheels to the soil surface in response to the generated signal from the trench closing sensor.
