Abstract

In one aspect, a system for determining soil parameters of a field across which an agricultural implement is being moved may include a sensor mounted on a ground engaging member. As such, the sensor may be configured to capture data indicative of a soil parameter of soil within the field. Furthermore, the system may include a controller configured to receive an input indicative of a selected planting depth for the field. Moreover, the controller may be configured to control an operation of an actuator in a manner that adjusts the penetration depth of the ground engaging member such that the sensor is positioned at the selected planting depth. Additionally, the controller may be configured to determine the soil parameter of the soil within the field at the selected planting depth based on the data received from the sensor.

First claim

The invention claimed is:

1. A system for determining soil parameters of a field across which an agricultural implement is being moved, the system comprising:
a ground engaging member configured to penetrate soil within the field;
an actuator configured to adjust a penetration depth of the ground engaging member;
a sensor mounted on the ground engaging member, the sensor configured to capture data indicative of a soil parameter of soil within the field;
a controller communicatively coupled to the sensor, the controller configured to:
receive an input indicative of a selected planting depth for the field;
control an operation of the actuator in a manner that adjusts the penetration depth of the ground engaging member such that the sensor is positioned at the selected planting depth; and
determine the soil parameter of the soil within the field at the selected planting depth based on the data received from the sensor;
wherein the controller is further configured to monitor the soil parameter relative to a threshold soil parameter value and initiate a control action when the monitored soil parameter has exceeded or fallen below the threshold soil parameter value;
wherein the control action comprises adjusting an operating parameter of the agricultural implement;
wherein the operating parameter comprises a ground speed of the agricultural implement.

2. The system of claim 1 , wherein the soil parameter comprises at least one of an amount of soil aggregates at the selected planting depth, a degree of aeration at the selected planting depth, a presence of residue at the selected planting depth, an amount of residue at the selected planting depth, an amount of organic matter at the selected planting depth, a moisture content of the soil at the selected planting depth, or a temperature of the soil at the selected planting depth.

3. The system of claim 1 , further comprising:
a ground engaging tool configured to penetrate the soil in a manner that performs an agricultural operation on the soil within the field, wherein a penetration depth of the ground engaging tool is independent of the penetration depth of the ground engaging member.

4. The system of claim 1 , wherein the control action comprises notifying an operator of the agricultural implement that the monitored soil parameter has exceeded or fallen below the threshold soil parameter value.

5. The system of claim 1 , further comprising:
a ground engaging tool configured to penetrate the soil in a manner that performs an agricultural operation on the soil within the field, the operating parameter comprising a penetration depth of the ground engaging tool.

6. The system of claim 1 , further comprising:
a disc gang, the operating parameter comprising an angle of the disc gang.

7. The system of claim 1 , wherein the controller is further configured to generate a field map illustrating the soil parameter at one or more locations within the field.

8. The system of claim 1 , wherein the sensor comprises at least one of a multispectral sensor, an optical sensor, or a dielectric sensor.

9. A method for determining soil parameters of a field across which an agricultural implement is being moved, the agricultural implement including a ground engaging member and a sensor mounted on the ground engaging member, the method comprising:
receiving, with a computing device, an input indicative of a selected planting depth for the field;
controlling, with the computing device, an operation of an actuator in a manner that adjusts a penetration depth of the ground engaging member such that the sensor is positioned at the selected planting depth;
determining, with the computing device, a soil parameter of soil within the field at the selected planting depth based on data received from the sensor;
monitoring, with the computing device, the soil parameter relative to a threshold soil parameter value; and
when the monitored soil parameter exceeds or falls below the threshold soil parameter value, imitating, with the computing device, a control action;
wherein the control action comprises adjusting an operating parameter of the agricultural implement;
wherein the operating parameter comprises a ground speed of the agricultural implement.

10. The method of claim 9 , wherein the soil parameter comprises at least one of an amount of soil aggregates at the selected planting depth, a degree of aeration at the selected planting depth, a presence of residue at the selected planting depth, an amount of residue at the selected planting depth, an amount of organic matter at the selected planting depth, a moisture content of the soil at the selected planting depth, or a temperature of the soil at the selected planting depth.

11. The method of claim 9 , wherein the control action comprises notifying an operator of the agricultural implement that the monitored soil parameter has exceeded or fallen below the threshold soil parameter value.

12. The method of claim 9 , wherein the operating parameter comprises a penetration depth of a ground engaging tool of the agricultural implement.

13. The method of claim 9 , wherein the operating parameter comprises an angle of a disc gang of the agricultural implement.

14. The method of claim 9 , further comprising:
generating, with the computing device, a field map illustrating the soil parameter at one or more locations within the field.
