Agricultural input selection systems, methods and apparatus

1. A system for selecting an agricultural input, comprising: a first input source of a first seed;

a second input source of a second seed;

a meter having a seed disc, said meter in communication with said first input source of said first seed and said second input source of said second seed;

a selection apparatus which constrains said meter to deposit only said first seed or said second seed at one time;

processing circuitry in electrical communication with said selection apparatus, said processing circuitry configured to send a command signal to said selection apparatus in order to modify a configuration of said selection apparatus from a first configuration to a second configuration, wherein in said first configuration said meter deposits said first seed, and wherein in said second configuration said meter deposits said second seed;

wherein said selection apparatus includes:

a first segregated pool of said first seed;

a second segregated pool of said second seed; and

a central seed pool in communication with said seed disc;

a first gate separating said first segregated pool of said first seed from said central seed pool;

a second gate segregating said second segregated pool of said second seed from said central seed pool;

a first gate actuator configured to raise and lower said first gate; and a second gate actuator configured to raise and lower said second gate;

wherein said processing circuitry alternately commands said first and second gate actuators to respectively raise said first gate and said second gate, whereby said seed disc is selectively placed in communication with one of said first and said second segregated pools.

2. The system of claim 1 , wherein said first seed pool and said second seed pool are disposed on a conveyor, said conveyor movable between a first position in which said first seed pool is in communication with said seed disc and a second position in which said second seed pool is in communication with said seed disc.

3. The system of claim 1 , further comprising:

a seed level sensor in electrical communication with said processing circuitry.

4. The system of claim 3 , wherein said seed level sensor is disposed to generate a signal when an amount of said first or said second seed in said central seed pool is less than a threshold amount.

5. A system for selecting an agricultural input, comprising: a first input source of a first seed;

a second input source of a second seed;

a meter in communication with said first input source of said first seed and said second input source of said second seed;

a selection apparatus whereby said meter is constrained to deposit only said first seed or said second seed at one time, and whereby said meter is capable of alternating between depositing said first seed and said second seed;

processing circuitry in electrical communication with said selection apparatus, said processing circuitry configured to send a command signal to said selection apparatus in order to modify a configuration of said selection apparatus from a first configuration to a second configuration, wherein in said first configuration said meter deposits said first seed, and wherein in said second configuration said meter deposits said second seed;

wherein said meter includes a seed disc, said seed disc having a first array of seed apertures and a second array of seed apertures, said second array concentrically arranged with respect to said first array;

wherein said selection apparatus includes:

a first seed pool of said first seed, said first seed pool in communication with said first array of seed apertures;

a second seed pool of said second seed, said second seed pool in communication with said second array of seed apertures; and

a key having a first position and a second position, wherein in said first position said key prevents said first seed of said first seed pool in communication with said first array of seed apertures from being deposited, and wherein in said second position said key prevents said second seed of said second seed pool in communication with said second array of seed apertures from being deposited; and

an actuator operably connected to said key, said actuator disposed to move said key between said first position and said second position.

6. The system of claim 5 , wherein said actuator is in communication with said processing circuitry, said processing circuitry configured to send a control signal to said actuator such that said actuator alternates between said first position and said second position.

7. The system of claim 5 , further comprising:

a first singulator disposed to remove excess seeds from said first array of seed apertures; and

a second singulator disposed to remove excess seeds from said second array of seed apertures.

8. The system of claim 7 , wherein said first singulator is disposed between said first seed pool and said key, and wherein said second singulator is disposed between said second seed pool and said key.

9. The system of claim 7 , wherein said key is disposed to knock said first seed from said first array of seed apertures into said first seed pool in said first position, and wherein said key is disposed to knock said second seed from said second array of seed apertures into said second seed pool.

10. The system of claim 5 , further including:

a motor for driving said seed disc at variable speeds, said motor in communication with said processing circuitry for receiving a speed command signal corresponding to a rotational speed of said seed disc, wherein said processing circuitry modifies said speed command signal based on a position of said key.
