Abstract
Abstract A global positioning planter system for planting of seeds by a seed planter. A population control controls the seed planter. A global positioning system computer with digitized maps connects to the population control. The population control connects to the seeder for planting of seeds such as corn or beans or to seed drills for controlling the seed drill, and plants the seeds according to the population control which receives and transmits data with the global positioning system computer.
