Abstract

Disclosed herein are methods, systems, and devices for rhizosphere imaging. Methods include applying a signal to a portion of a plant and its roots via at least one first electrode, receiving the signal via at least one second electrode placed a designated distance from the plant, and generating, using one or more processors, a rhizosphere model based, at least in part, on the received signal, the generating of the rhizosphere model being implemented based, at least in part, on one or more frequency characteristics of the received signal.

Claims (38)

1 . A method comprising:

applying a signal to a portion of a plant and its roots via at least one first electrode, the roots having a physical parameter;

receiving the signal via at least one second electrode placed a designated distance from the plant; and

generating, using one or more processors, a rhizosphere model based, at least in part, on the received signal, the generating of the rhizosphere model being implemented based, at least in part, on one or more frequency characteristics of the received signal.

2 . The method of claim 1 , wherein the rhizosphere model comprises a rhizosphere metric representing the physical parameter of the roots of the plant.

3 . The method of claim 1 or claim 2 , wherein the physical parameter is an estimated length of the roots of the plant.

4 . The method of claim 1 , wherein the at least one first electrode is included in a plurality of first electrodes, and wherein the at least one second electrode is included in a plurality of second electrodes.

5 . The method of claim 1 or claim 4 , wherein the rhizosphere model comprises a rhizosphere tomography.

6 . The method of claim 5 further comprising:

generating a rhizosphere display object based, at least in part, on the rhizosphere tomography, the rhizosphere display object being capable of being displayed in a display device.

7 . The method of claim 1 further comprising:

generating a data object based on the rhizosphere model, the data object capable of being transmitted via a communications network.

8 . The method of claim 7 further comprising:

transmitting the data object via a communications interface.

9 . The method of claim 8 , wherein the communications interface is compatible with a WiFi communications protocol.

10 . A system comprising:

at least one first electrode coupled to a portion of a plant and its roots;

at least one second electrode placed a designated distance from the plant; and

a rhizosphere modeler comprising one or more processors configured to:

generate a signal applied to the at least one first electrode;

obtain a plurality of measurements based on a signal received via the at least one second electrode; and

generate a rhizosphere model based, at least in part, on the received signal, the generating of the rhizosphere model being implemented based, at least in part, on one or more frequency characteristics of the received signal.

11 . The system of claim 10 , wherein the rhizosphere model comprises a rhizosphere metric representing a physical parameter of the roots of the plant, and wherein the physical parameter is an estimated length of the roots of the plant.

12 . The system of claim 10 , wherein the at least one first electrode is included in a plurality of first electrodes, and wherein the at least one second electrode is included in a plurality of second electrodes.

13 . The system of claim 10 or claim 12 , wherein the rhizosphere model comprises a rhizosphere tomography.

14 . The system of claim 13 , wherein the one or more processors are further configured to:

generate a rhizosphere display object based, at least in part, on the rhizosphere tomography, the rhizosphere display object being capable of being displayed in a display device.

15 . The system of claim 10 , wherein the rhizosphere modeler is included in a portable housing.

16 . A device comprising:

a signal generator configured to generate a signal applied to at least one first electrode coupled to a plant and its roots; and

one or more processors configured to:

obtain a plurality of measurements based on a signal received via at least one second electrode; and

generate a rhizosphere model based, at least in part, on the received signal, the generating of the rhizosphere model being implemented based, at least in part, on one or more frequency characteristics of the received signal.

17 . The device of claim 16 , wherein the rhizosphere model comprises a rhizosphere metric representing a physical parameter of the roots of the plant, and wherein the physical parameter is an estimated length of the roots of the plant.

18 . The device of claim 16 , wherein the at least one first electrode is included in a plurality of first electrodes, and wherein the at least one second electrode is included in a plurality of second electrodes.

19 . The device of claim 16 or claim 18 , wherein the rhizosphere model comprises a rhizosphere tomography.

20 . The device of claim 19 , wherein the one or more processors are further configured to:

generate a rhizosphere display object based, at least in part, on the rhizosphere tomography, the rhizosphere display object being capable of being displayed in a display device.
