Abstract

A system and method for controlling a planter comprises a boundary definer for establishing a boundary associated with a field. A location-determining receiver determines a position of a planter. A detector is capable of generating an activation signal if the location-determining receiver crosses the established boundary. An actuator is arranged for interrupting the dispensing of seed for a single planter row for a specified time duration or over a specified range of positions in response to the activation signal.

Claims

1. A system for controlling a planter, the system comprising:

a boundary definer for establishing a boundary associated with a field;

a location-determining receiver for determining a position of a planter;

a detector for generating an activation signal if the determined position of the location-determining receiver crosses the established boundary; and

an actuator for interrupting the dispensing of seed or another crop precursor for a planter row for a specified time duration or over a specified range of positions in response to the activation signal.

2. The system according to claim 1 wherein the planter row comprises at least one outer row of the planter.

3. The system according to claim 1 wherein the actuator disrupts the dispensing of the seed or the crop precursor for the specified time duration for an outer row of the planter to produce a visually observable notch or absence of crop plants in a planted row of crop.

4. The system according to claim 1 wherein the actuator disrupts the dispensing of the seed or the crop precursor over the specified range of positions for an outer row of the planter to produce a visually observable notch or absence of crop plants in a planted row of crop.

5. The system according to claim 1, wherein the actuator interrupts the dispensing of seed or the crop precursor for the specified time duration or over the specified range to produce a visually observable notch in the planted rows of crop when the dispensed seed matures.

6. The system according to claim 1 further comprising:

a user interface for allowing an operator of the planter to select at least one of a number of outer rows, the specified time duration and the specified range.

7. The system according to claim 1 wherein the boundary comprises a contour or linear segment spaced apart from an edge or external edge of the field.

8. The system according to claim 1 wherein the boundary comprises an internal boundary within the field, the internal boundary associated with a waterway, a grassland zone, a traversable zone, or a non-traversable zone that is not traversable by the planter.

9. The system according to claim 1 further comprising a data storage device for storing a position of the planter associated with the activation of the actuator, the deactivation of the actuator, or both.

10. The system according to claim 1 wherein the actuator further comprises:

a supply container for storing the seed or the crop precursor;

a dispensing valve having an inlet and an outlet, the inlet in communication with the supply container elevated above the dispensing valve; and

the actuator arranged for opening the dispensing valve to provide an open state to facilitate movement of the seed or the crop precursor, at least partially by gravity, from the inlet to the outlet.

11. The system according to claim 1 further comprising:

a seed supply container for storing the seed or the crop precursor;

a dispensing valve having an inlet and an outlet, the inlet in pneumatic communication with the supply container; and

the actuator arranged for opening the dispensing valve to provide an open state to facilitate movement of the seed or the precursor, at least partially by an air or gaseous pressure differential, between the inlet to the outlet.

12. A method for controlling a planter, the method comprising:

establishing a boundary associated with a field;

determining a position of a planter via a location-determining receiver;

generating an activation signal if the determined position of the planter crosses the established boundary; and

interrupting the dispensing of seed or another crop precursor for a planter row for a specified time duration or over a specified range of positions in response to the activation signal.

13. The method according to claim 12 wherein the planter row comprises at least one outer row of the planter.

14. The method according to claim 12 wherein the interrupting further comprises disrupting the dispensing of the seed or the crop precursor for the specified time duration for an outer row of the planter to produce a visually observable notch or absence of crop plants in a planted row of crop.

15. The method according to claim 12 wherein the interrupting further comprises disrupting the dispensing of the seed or the crop precursor over the specified range of positions for an outer row of the planter to produce a visually observable notch or absence of crop plants in a planted row of crop.

16. The method according to claim 12 wherein the interrupting further comprises interrupting the dispensing of seed or the crop precursor for the specified time duration or over the specified range to produce a visually observable notch in the planted rows of crop when the dispensed seed matures.

17. The method according to claim 12 further comprising:

allowing an operator of the planter to select at least one of a number of outer rows, the specified time duration and the specified range.

18. The method according to claim 12 wherein the boundary comprises a contour or linear segment spaced apart from an edge or external edge of the field.

19. The method according to claim 12 wherein the boundary comprises an internal boundary within the field, the internal boundary associated with a waterway, a grassland zone, a traversable zone, or a non-traversable zone that is not traversable by the planter.

20. The method according to claim 12 further comprising:

storing a position of the planter associated with the activation of an actuator, the deactivation of the actuator, or both.
