Seeding control system and method

A method of monitoring and controlling seed placement by a planter during planting operations, wherein said planter comprises a plurality of swaths, each swath comprising at least one row unit, wherein each swath includes at least one drive, the at least one drive controlling dispensing of seeds from the at least one row unit of the swath, each row unit having a seed sensor configured to generate a seed pulse upon passage of each dispensed seed through a seed path, said method comprising:

• a) generating a start signal, said at least one drive responsive to said start signal to start dispensing of seeds from said at least one row unit;
• b) determining a start delay by measuring a time difference between said generation of said start signal until a first seed pulse is thereafter generated from said at least one row unit;
• c) storing in memory said start delay;
• d) generating a stop signal, said at least one drive responsive to said stop signal to stop dispensing of seeds from said at least one row unit;
• e) determining a stop delay by measuring a time difference between said generation of said stop signal until a last seed pulse is thereafter generated from said at least one row unit;
• f) storing in memory said stop delay;
• g) as the planter traverses said field during planting operations, associating a GPS location with each generated seed pulse;
• h) generating a seed placement map of said field by storing in memory a seed placement location of each seed, wherein each said seed placement location is associated with each said GPS location associated with each said generated seed pulse;
• i) during planting operations, engaging said at least one drive by accounting for said start delay to achieve a desired start seed placement location;
• and
• j) during planting operations, disengaging said at least one drive by accounting for said stop delay to achieve a desired stop seed placement location.
