Abstract

Systems, apparatuses, and methods for agricultural monitoring of soil characteristics and determining soil color are described herein. In one example, a method of calculating soil color data includes obtaining, with sensors of a soil apparatus, soil measurements. The method further includes calculating soil color values in a visible spectrum including at least one of red, green, and blue color values based on the soil measurements and determining color data for at least one color image without false image artifacts based on the calculated soil color values and associated coordinates within an agricultural field.

Claims (30)

1. A method of calculating soil color data, the method comprising:

obtaining, with sensors of a soil apparatus that emit and detect one or more of non-red (R) green (G) blue (B) wavelengths of light, a sequence of subsurface soil color measurements including at least one of measurements for moisture, organic matter, porosity, type of soil, or furrow residue during an agricultural input of an agricultural implement having the soil apparatus;

calculating, with processing logic, soil color values in a visible light spectrum including at least one of red, green, and blue color values based on the soil color measurements from the one or more non-RGB wavelengths of light; and

determining color data for at least one color image without false image artifacts based on the calculated soil color values and associated coordinates within an agricultural field.

2. The method of claim 1 , further comprising:

presenting the at least one color image on a display device or monitor without any false image artifacts.

3. The method of claim 1 , wherein the soil measurements are obtained without measuring at least one of red, green, and blue wavelengths of light.

4. The method of claim 1 , wherein the blue color values are calculated based on measuring a 460 nm wavelength of light.

5. The method of claim 1 , wherein the green color values are calculated based on measuring a 460 nm wavelength of light and measuring a 589 nm wavelength of light for yellow.

6. The method of claim 1 , wherein the red color values are calculated based on measuring a 460 nm wavelength of light, measuring a 589 nm wavelength of light for yellow, and measuring a 850 nm wavelength of light.

7. The method of claim 1 , further comprising:

generating a signal in real time during an agricultural operation to actuate any implement on any agricultural implement in response to obtaining soil measurements.

8. The method of claim 7 , wherein the actuation of any implement causes one or more of a change in a population of planted seeds by controlling a seed meter, a change in seed variety, a change in furrow depth, a change in application rate of fertilizer, fungicide, and/or insecticide, or a change in applied downforce or upforce of an agricultural implement in response to obtaining soil measurements.

9. The method of claim 1 , wherein the soil apparatus comprises a seed firmer to obtain soil measurements including at least one of measurements for moisture, organic matter, porosity, type of soil, and furrow residue.

10. The method of claim 1 , wherein the sensors comprise reflective sensors positioned on an implement at a planting depth of soil.

11. A system for monitoring soil characteristics, the system comprising:

sensors to emit and detect one or more of non-red (R) green (G) blue (B) wavelengths of light to obtain subsurface soil color measurements including at least one of measurements for moisture, organic matter, porosity, type of soil, or furrow residue during an agricultural input of an agricultural implement;

a communication unit to receive data including the soil color measurements sensed from the sensors of the agricultural implement; and

processing logic coupled to the communication unit, wherein the processing logic is configured to receive the soil color measurements including at least one of measurements for moisture, organic matter, porosity, type of soil, or furrow residue,

to calculate soil color values in a visible light spectrum including at least one of red, green, and blue color values based on the received soil color measurements from the one or more non-RGB wavelengths of light, and

to determine color data for at least one color image without false image artifacts based on the calculated soil color values and associated coordinates within an agricultural field.

12. The system of claim 11 , wherein the processing logic is further configured to send the at least one color image to a display device or monitor.

13. The system of claim 11 , wherein the soil measurements are obtained without measuring at least one of red, green, and blue wavelengths of light.

14. The system of claim 11 , wherein the blue color values are calculated based on measuring a 460 nm wavelength of light.

15. The system of claim 11 , wherein the green color values are calculated based on measuring a 460 nm wavelength of light and measuring a 589 nm wavelength of light for yellow.

16. The system of claim 11 , wherein the red color values are calculated based on measuring a 460 nm wavelength of light, measuring a 589 nm wavelength of light for yellow, and measuring a 850 nm wavelength of light.

17. The system of claim 11 , wherein the processing logic is further configured to generate a signal in real time during an agricultural operation to cause actuation of any implement on any agricultural implement in response to obtaining soil measurements.

18. The system of claim 17 , wherein the actuation of any implement causes one or more of a change in a population of planted seeds by controlling a seed meter, a change in seed variety, a change in furrow depth, a change in application rate of fertilizer, fungicide, and/or insecticide, or a change in applied downforce or upforce of an agricultural implement in response to obtaining soil measurements.

19. The system of claim 11 , wherein the soil measurements are obtained from sensors of a seed firmer of the agricultural implement.

20. The system of claim 11 , wherein the sensors comprise reflective sensors positioned on the agricultural implement at a planting depth of soil.
