Abstract
A seeding control system and method to improve yield by minimizing overplanting and underplanting during planting operations. As the planter traverses the field, a precise seed placement map is created by associating the time of each seed pulse generated by the seed sensors with the location of a GPS unit. Based on the generated seed placement map, a stop-planting boundary is defined by previously planted seed or other field boundary such that when a swath of the planter crosses over the stop-planting boundary the swath controllers disengage the drivers of the corresponding seed meters to prevent planting of seeds. The swath controllers cause the drivers to reengage allowing planting to resume when the affected swaths pass out of the stop planting boundary.
