A soil disinfector comprising an insulating endless belt with at least one row of positive electrodes and at least one row of negative electrodes mounted on the endless belt. The electrodes are mounted with their heads on the inside of the belt and their bodies pointing outward from the belt, the electrodes being configured to penetrate the soil. The electrodes take their power from a power source, the power source being connected to the electrodes via sets of rows of rollers and sets of rows of stationary conductive contact plates, at least one set of each being positive and at least one set of each being negative. The soil disinfector also has sensors to detect soil conditions and a processor to alter power applied to the soil based on the soil conditions.

An agricultural planting or seeding implement that includes a ground engaging tool that forms a trench in a field. The ground engaging tool includes a blade that forms the trench. A first conduit couples to the blade. The first conduit deposits agricultural product in the field. A sensor couples to the ground engaging tool. The sensor generates a signal indicative of a soil property of the field.

An agricultural planting or seeding implement having a ground engaging tool that forms an opening along an axis in the soil, a sensor disposed aft of the ground engaging tool, and a row unit disposed aft of both the ground engaging tool and the sensor relative to a direction of travel of the agricultural planting or seeding implement. The sensor engages with the ground at a depth within the opening and generates a signal indicative of a soil property of the ground.

In one aspect, a system for monitoring soil composition within a field using an agricultural machine may include a ground-engaging tool configured to rotate relative to soil within a field as the agricultural machine is moved across the field. The ground-engaging tool may, in turn, include a tooth defining a cavity therein, with the cavity including an opening. Furthermore, the system may include a sensor positioned within the cavity, with the sensor configured emit an output signal through the opening for reflection off of the soil within the field. The sensor may also be configured to detect the reflected output signal as a return signal, with a parameter of the return signal being indicative of a soil composition of the soil within the field.

A system for sensing characteristics of a trench in a soil surface during planting operations. A trench opening assembly opens a trench in the soil surface as the trench opening assembly moves in a forward direction of travel. A trench closing assembly disposed rearward of the trench opening assembly closes the opened trench with soil. One or more sensors may be disposed on an appurtenance disposed in said trench configured to provide characteristics of an area of the open trench or an area of the trench closed with soil by the trench closing assembly or a sensor may be disposed outside of said trench configured to provide characteristics of an area of the trench closed with soil or a combination of the sensors may be disposed in the trench and outside of the trench.

A soil imaging system having a work layer sensor disposed on an agricultural implement to generate an electromagnetic field through a soil area of interest as the agricultural implement traverses a field. A monitor in communication with the work layer sensor is adapted to generate a work layer image of the soil layer of interest based on the generated electromagnetic field. The work layer sensor may also generate a reference image by generating an electromagnetic field through undisturbed soil. The monitor may compare at least one characteristic of the reference image with at least one characteristic of the work layer image to generate a characterized image of the work layer of interest. The monitor may display operator feedback and may affect operational control of the agricultural implement based on the characterized image.

A soil measurement system is provided, comprising a soil surveying device, a radio receiver, a plurality of subterranean antennas, and a processor. The soil surveying device comprises a wireless radio transmitter configured to emit a wireless signal at a predetermined bandwidth in a predetermined spectrum. The plurality of subterranean antennas are in an array electronically connected to the radio receiver and configured to be mounted in a subterranean environment at different depths in the subterranean environment. Each of the plurality of subterranean antennas is configured to receive the wireless signal at a respective point in time. The processor is configured to determine a relative time of flight of the received wireless signal between the plurality of antennas at the respective point in time, and estimate a soil permittivity based on the determined relative time of flight. The measurement system may be applied to materials other than soil, in some examples.

A system for measuring soil properties on-the-go uses soil-engaging components of an existing farm implement as electrodes for a soil conductivity measurement system. The soil-engaging components can be: electrically isolated shanks and/or replaceable points or sweeps on a tillage implement; a row cleaner or coulter device on the front of a planter row unit, the closing wheels on the back of the planter row unit, or an entire planter row unit; or an additional soil contacting component added to an existing implement shank. A soil engaging component serving as an electrode is electrically isolated from other components of the implement. A soil conductivity measurement is made by passing current between a first pair of soil-engaging electrodes and measuring voltage resulting from the current between a second pair of soil-engaging electrodes. A narrow profile sensor unit can be attached to the implement to measure additional soil properties.

In one aspect, a system for controlling the operation of an agricultural implement may include an agricultural implement configured to perform an agricultural operation on a field as the implement is moved across the field. A controller of the system configured to receive data indicative of a plurality of field characteristics of the field. The controller may also be configured to determine first and second soil moisture content values of the soil within the field at first and second depths below a field surface of the field based on the received data, respectively. Additionally, the controller may be configured to initiate adjustment of an operating parameter of the agricultural implement based on the determined the first soil moisture content value and the determined second soil moisture content value.

The present invention relates to a potential difference-based diversion electrode arrangement and field intensity compensation method, comprising the following steps: the arrangement positions of paired diversion electrodes are determined according to the difference of potential around a position of field intensity to be compensated and the direction of an electric field line, and the paired diversion electrodes are inserted; and the field intensity enhancement rate of the position of field intensity to be compensated and the compensated field intensity value are calculated according to the difference of potential and arrangement positions of the paired diversion electrodes. In the present invention, the paired diversion electrodes are arranged in the direction of the electric field line by using the spatial difference of potential in the electric field, and the compensation of local field intensity is implemented, thereby beneficial to improving the overall efficiency of electrokinetic remediation for organic contaminated soil, and reducing the spatial difference of remediation efficiency.
