A monitoring system for an agricultural implement having a plurality of row units (500; 500'), the system including for each of the plurality of row units (500; 500'): a seed meter configured to dispense seeds and a seed meter drive module for controlling the seed meter speed, a seed conveyor and a conveyor module for controlling the seed conveyor speed, the seed conveyor including a rotatable belt having a plurality of flights, said seed conveyor having forward side and a rearward side with respect to a forward direction of travel, said belt disposed to receive said seeds dispensed from said seed meter between said flights as said belt rotates, said flights guiding said dispensed seeds down said forward side of said seed conveyor to a lower end of said seed conveyor, whereupon said dispensed seeds are released from between said flights and exit said seed conveyor at said lower end, and wherein said flights ascend said rearward side of said seed conveyor after said dispensed seeds are released from between said flights; the monitoring system comprising a monitor having a processor wherein it further comprises: a respective first seed sensor mounted to said forward side of each of said seed conveyors, each of said first seed sensors generating a respective first signal corresponding to each said flight and dispensed seed descending past said first seed sensor; a respective second seed sensor mounted to said rearward side of each of said seed conveyors, each of said second seed sensors generating a respective second signal corresponding to each said flight ascending past said second seed sensor without said dispensed seed; said monitor in data communication with each of said first seed sensors and each of said second seed sensors to respectively receive each of said generated first and second signals; and a row control module (200, 202) in data communication with said monitor and with said seed meter drive module and said seed conveyor module of at least one of the plurality of row units (500; 500'), said row control module configured to send commands to the seed meter drive module and conveyor module to adjust, based on said signals (1810, 1820) for said at least one of the plurality of row units, a rate at which said seed meter dispenses said dispensed seeds and a conveyor speed. a seed meter configured to dispense seeds and a seed meter drive module for controlling the seed meter speed, a seed conveyor and a conveyor module for controlling the seed conveyor speed, the seed conveyor including a rotatable belt having a plurality of flights, said seed conveyor having forward side and a rearward side with respect to a forward direction of travel, said belt disposed to receive said seeds dispensed from said seed meter between said flights as said belt rotates, said flights guiding said dispensed seeds down said forward side of said seed conveyor to a lower end of said seed conveyor, whereupon said dispensed seeds are released from between said flights and exit said seed conveyor at said lower end, and wherein said flights ascend said rearward side of said seed conveyor after said dispensed seeds are released from between said flights;

said monitor in data communication with each of said first seed sensors and each of said second seed sensors to respectively receive each of said generated first and second signals; and a row control module (200, 202) in data communication with said monitor and with said seed meter drive module and said seed conveyor module of at least one of the plurality of row units (500; 500'), said row control module configured to send commands to the seed meter drive module and conveyor module to adjust, based on said signals (1810, 1820) for said at least one of the plurality of row units, a rate at which said seed meter dispenses said dispensed seeds and a conveyor speed. a respective first seed sensor mounted to said forward side of each of said seed conveyors, each of said first seed sensors generating a respective first signal corresponding to each said flight and dispensed seed descending past said first seed sensor; a respective second seed sensor mounted to said rearward side of each of said seed conveyors, each of said second seed sensors generating a respective second signal corresponding to each said flight ascending past said second seed sensor without said dispensed seed; said monitor in data communication with each of said first seed sensors and each of said second seed sensors to respectively receive each of said generated first and second signals; and a row control module (200, 202) in data communication with said monitor and with said seed meter drive module and said seed conveyor module of at least one of the plurality of row units (500; 500'), said row control module configured to send commands to the seed meter drive module and conveyor module to adjust, based on said signals (1810, 1820) for said at least one of the plurality of row units, a rate at which said seed meter dispenses said dispensed seeds and a conveyor speed.
