Seed research plot planter and field layout system

A seed planter, comprising:

• a seed chamber for receiving seeds to be planted;
• a rotating seed plate that cooperates with the seed chamber to pick up and transport individual seeds from the seed chamber to a release point, where the seeds fall to the earth;
• a sensor that detects the rotational position of the rotating seed plate;
• a controller that receives a first signal from said sensor and uses said first signal to control a function of the planter;
• and
• a distance measuring device associated with the planter for measuring a distance traveled by the planter, and wherein said controller receives a second signal from said distance measuring device and uses said second signal to control the rotation of the rotating seed plate;
• wherein said distance measuring device comprises an encoder associated with a ground engaging wheel of the seed planter.

• and
• a speed sensor and a timer, wherein said computer algorithm uses the GPS signal together with an output from said speed sensor and said timer to generate and output said location signal at a pulse frequency that varies with the speed of the planter.

• wherein said controller comprises a programmable means for using said first signal and said second signal to control said planter function based on the rotational position of said rotating seed plate and the location of the planter within a field;
• wherein said programmable means comprises a means for programming a plurality of planter functions to occur in a predetermined sequence based on the position of the planter in the field, and wherein said controller ensures that the rotational position of the rotating seed plate is precisely matched to the position of the planter in the field;
• and
• wherein said seed planter is a seed research plot planter for planting multiple plots of seeds with each plot having a different seed type, and wherein said plurality of planter functions comprises:
• a seed staging function in which seeds are placed in a staging area just above the seed chamber;
• a seed loading function in which seeds are dropped from the seed staging area into the seed chamber;
• a seed singulation function in which seeds in the seed chamber are picked up on the rotating seed plate and dropped off of the rotating seed plate at said release point;
• an evacuation and restaging function in which a wiper element prevents additional seeds from being picked up on the rotating seed plate and excess seeds in the seed chamber are evacuated;
• and
• an alley narrowing function in which the rotating seed plate is rotated faster when the planter is in an alleyway to advance new seeds picked up on the rotating seed plate to the drop off point quicker to shorten the alleyway to a predetermined width.

• a rotating seed plate that cooperates with the seed chamber to pick up and transport individual seeds from the seed chamber to a release point, where the seeds fall to the earth;
• a sensor that detects the rotational position of the rotating seed plate;
• a controller that receives a first signal from said sensor and uses said first signal to control a function of the planter;
• and
• an alley wiper that can be activated to wipe seeds from the rotating seed plate to create an alley with no planted seeds in the field between plots, and a means for activating said alley wiper once the last seed on the rotating seed plate needed for a plot clears the alley wiper.

• a rotating seed plate that cooperates with the seed chamber to pick up and transport individual seeds from the seed chamber to a release point, where the seeds fall to the earth;
• and
• a controller that controls a function of the planter to start and stop planting, said controller using a planter setback parameter corresponding to a distance between a GPS receiver and a predetermined location on the planter to determine when to start and stop planting at a predetermined location within a field, and further comprising an algorithm that adjusts the planter setback parameter based on the ground speed of the planter.
