Soil quality measurement device
Systems, methods and apparatus are provided for soil testing. In some embodiments, a soil sample quality criterion is determined and associated with the soil sample. In some embodiments a soil characteristic measurement is additionally taken and associated with the soil sample. In some embodiments, the soil sample and its associated data are associated with a container in which the soil sample is placed.
1. A method for soil testing, comprising:
positioning a soil probe above a region of soil;
obtaining, by the soil probe, a soil sample when the soil probe is extended at a first depth into soil in the region of soil;
obtaining, by a soil characteristic sensor coupled to the soil probe, soil characteristic measurements of the soil sample to determine sample quality criterion for the soil sample;
determining, by a computing device communicatively coupled to the soil probe, whether the sample quality criterion exceeds a first threshold;
after determining that the sample quality criterion exceeds the first threshold, determining a location of the region of the soil using a global positioning receiver of the computing device; and
associating, by the computing device, an identifier of the soil sample with the location of the region of the soil.
2. The method of claim 1 , wherein the step of determining sample quality criterion for the soil sample is performed in response to identifying a threshold sample capture criterion.
3. The method of claim 1 , wherein the step of determining sample quality criterion comprises measuring an angle of orientation of the soil probe.
4. The method of claim 1 , wherein the step of associating an identifier of the soil sample with the location of the region of the soil is performed in response to an indication to accept the soil sample.
5. The method of claim 1 , further comprising:
applying a force to the soil probe to cause the soil probe to obtain the soil sample;
using the computing device, determining whether the force exceeds a second threshold; and
upon determining that the force exceeds the second threshold, automatically obtaining a photographic image of the region of the soil using a camera communicatively coupled to the computing device.
6. The method of claim 1 , further comprising automatically obtaining a photographic image of the region of soil using a camera communicatively coupled to the computing device.
7. The method of claim 1 , further comprising:
transferring the soil sample to a container; and
associating, by the computing device, the identifier of the soil sample with the container.
8. The method of claim 7 , wherein the step of associating the identifier of the soil sample with the container comprises:
receiving a container code; and
associating the container code with the identifier of the soil sample.
9. The method of claim 8 , wherein the container code is stored on a near-field communication device.
10. The method of claim 1 , further comprising:
transferring the soil sample to a container; and
transmitting soil sample data to a wireless communication device affixed to the container.
11. The method of claim 10 , wherein the wireless communication device comprises a near-field communication device.
12. The method of claim 10 , wherein the soil sample data comprises one of the sample quality criterion, sample identification data, and soil characteristic data.
13. The method of claim 1 , further comprising associating, by the computing device, the identifier of the soil sample with the sample quality criterion.
14. The method of claim 1 , wherein the step of determining sample quality criterion comprises measuring a sample depth.
15. The method of claim 1 , further comprising providing an alert when the sample quality criterion does not exceed the first threshold.
16. The method of claim 1 , wherein the step of determining a location of the region of the soil is in response to an acceptance of the soil sample.
17. The method of claim 1 , further comprising automatically obtaining a photographic image, using a camera communicatively coupled to the computing device, of one or more depth markers along the soil probe.
