Abstract

A soil detection and planting apparatus. The apparatus includes a vehicle and a controller coupled to the vehicle. The apparatus further includes a planting device coupled to the vehicle, the planting device configured to plant seeds or plants into a soil material. The apparatus includes a ground penetrating radar sensor coupled to the vehicle. The ground penetrating radar soil sensor is configured to scan the soil material up to a designated depth beneath a surface of the soil material, wherein the ground penetrating radar soil sensor is further configured to provide a sensor feedback signal to the controller with respect to an intrinsic characteristic of the soil material. The controller is configured to instruct placement of a seed or a plant into the soil material based on the feedback signal.

Claims

1. A soil detection apparatus comprising:

a housing;

a controller;

a non-contact soil sensor coupled to the housing, the non-contact soil sensor configured to scan a soil material and to provide a sensor feedback signal to the controller with respect to a characteristic of the soil material; and

a location sensor configured to provide a location feedback signal to the controller;

wherein the controller is configured to create a map of the soil material based on the sensor feedback signal and the location feedback signal.

2. The apparatus of claim 1, wherein the soil characteristic is an intrinsic characteristic of the soil material comprising at least one of a composition of the soil material, a water property of the soil material, a presence of humus in the soil material, a density of the soil material, and a soil material porosity.

3. The apparatus of claim 1, wherein the controller analyzes the location feedback signal to determine a specific location of the soil characteristic.

4. The apparatus of claim 3, wherein the controller indicates the soil characteristic on the map at the specific location.

5. The apparatus of claim 1, wherein the characteristic is an extrinsic characteristic of the soil material.

6. The apparatus of claim 5, wherein the extrinsic characteristic comprises a presence of the soil material.

7. The apparatus of claim 5, wherein the extrinsic characteristic comprises a depth of the soil material.

8. The apparatus of claim 5, wherein the extrinsic characteristic comprises a presence of an object beneath the surface of the soil material.

9. The apparatus of claim 8, wherein the controller identifies the object based on the sensor feedback signal.

10. The apparatus of claim 5, wherein the controller analyzes the location feedback signal to determine a specific location of the extrinsic soil characteristic.

11. The apparatus of claim 10, wherein the controller updates the map with an indication of a location of the extrinsic soil characteristic.

12. The apparatus of claim 1, wherein the housing is configured to be mounted in a bed of a pickup truck.

13. The apparatus of claim 1, wherein the housing is part of the ground-driven vehicle.

14. An air-based soil detection apparatus comprising:

an aircraft;

a controller;

a soil sensor coupled to the aircraft, the soil sensor configured to locate at least a portion of an irrigation system contained within a soil material or on a surface of the soil material, wherein the soil sensor is further configured to provide a sensor feedback signal relating to the detected portion of the irrigation system to the controller; and

a location sensor coupled to the aircraft, the location sensor configured to provide a location feedback signal to the controller;

wherein the controller is configured to create a map of the soil material including a location of the portion of the irrigation system based on the sensor feedback signal and the location feedback signal.

15. The apparatus of claim 14, wherein the soil sensor is a ground penetrating radar unit that emits electromagnetic radio waves into the soil material.

16. The apparatus of claim 14, wherein the soil sensor is a reflection seismology sensor that transmits acoustic waves into the soil material.
