Abstract

In one aspect, a system for dispensing agricultural products into a field using an agricultural machine may include a metering device configured to control a rate at which an agricultural product is dispensed into the field. Furthermore, the system may include a controller configured to determine a density of a cover crop present within the field as the agricultural machine is moved across the field. Moreover, the controller may be configured to determine an adjustment to be made to the rate at which the agricultural product is being dispensed for use in growing a primary crop within the field based on the determined density. Additionally, the controller may be configured to control the operation of the metering device to execute the adjustment of the rate at which the agricultural product is being dispensed.

First claim

The invention claimed is:

1. A system for dispensing agricultural products into a field using an agricultural machine, the system comprising:
a metering device configured to control a rate at which an agricultural product is dispensed into the field; and
a controller configured to:
determine a density of a cover crop present within the field as the agricultural machine is moved across the field;
determine an adjustment to be made to the rate at which the agricultural product is being dispensed for use in growing a primary crop within the field based on the determined density; and
control the operation of the metering device to execute the adjustment of the rate at which the agricultural product is being dispensed.

2. The system of claim 1 , wherein the controller is further configured to:
access a field map indicative of the density of the cover crop within the field; and
determine the density of the cover crop present within the field based on the accessed field map as the agricultural machine is moved across the field.

3. The system of claim 2 , wherein the field map comprises a field map generated based on data collected during a previous agricultural operation.

4. The system of claim 1 , wherein the controller is further configured to:
determine a species of the cover crop present within the field; and
determine the adjustment to be made to the rate at which the agricultural product is being dispensed into the field based on the determined density and the determined species.

5. The system of claim 1 , wherein the agricultural product comprises a fertilizer.

6. The system of claim 1 , wherein the agricultural product comprises at least one of a herbicide or an insecticide.

7. The system of claim 1 , wherein the agricultural product comprises primary crop seeds.

8. The system of claim 1 , further comprising:
a sensor configured to capture data indicative of the density of the cover crop present within the field as the agricultural machine is being moved across the field, the controller being communicatively coupled to the sensor, the controller further configured to:
receive the captured data indicative of the density of the cover crop present within the field from the sensor; and
determine the density of the cover crop present within a field based on the received data.

9. The system of claim 8 , wherein the sensor has a field of view directed in front of the agricultural machine relative to a direction of travel of the agricultural machine.

10. The system of claim 8 , wherein the controller is further configured to generate a field map based on the determined density.

11. The system of claim 8 , wherein the sensor comprises a vision-based sensor.

12. A method for dispensing agricultural products into a field using an agricultural machine, the agricultural machine including a metering device configured to control a rate at which an agricultural product is dispensed, the method comprising:
determining; with one or more computing devices, a density of a cover crop present within the field as the agricultural machine is moved across the field;
determining, with the one or more computing devices, an adjustment to be made to the rate at which the agricultural product is being dispensed for use in growing a primary crop within the field based on the determined density; and
controlling, with the one or more computing devices, the operation of the metering device to execute the adjustment of the rate at which the agricultural product being is dispensed.

13. The method of claim 12 , further comprising:
accessing, with the one of more computing devices, a field map indicative of the density of the cover crop within the field, wherein determining the density of the cover crop comprises determining, with the one or more computing devices, the density of the cover crop present within the field based on the accessed field map.

14. The method of claim 13 , wherein the field map comprises a field map generated based on data collected during a previous agricultural operation.

15. The method of claim 12 , further comprising:
determining, with the one or more computing devices, a species of the cover crop present within the field, wherein determining the adjustment comprises determining, with the one or more computing devices, the adjustment to be made to the rate at which the agricultural product is being dispensed into the field based on the determined density and the determined species.

16. The method of claim 12 , wherein the agricultural product comprises a fertilizer.

17. The method of claim 12 , wherein the metering device comprises at least one of a pump or a valve and the agricultural product comprises at least one of a herbicide, an insecticide, or a fertilizer.

18. The method of claim 12 , wherein the metering device comprises a seed meter and the agricultural product comprises primary crop seeds.

19. The method of claim 12 , further comprising:
receiving, with the one or more computing devices, captured sensor data indicative of the density of the cover crop present within the field, wherein determining the density of the cover crop comprises determining, with the one or more computing devices, the density of the cover crop present within a field based on the received sensor data.

20. The method of claim 19 , further comprising:
generating, with the one or more computing devices, a field map based on the determined density.
