Electronic components are configured to measure the liquid agricultural product application rate between the first sensing plate and the second sensing plate.

An irrigation apparatus for dispersing liquid through a plant growing medium is disclosed. The apparatus includes a geometrically shaped container of variable size. The container has an outer wall with an inner surface, an open top, and a base portion configured to cover the plant growing medium. The base portion is configured with a plurality of holes for receiving liquid therethrough. The plurality of holes are configured as raised half-circles to block light and receive air, water, and nutrients. The container is configured with at least one center opening therethrough having an inner wall for receiving a plant. The center opening has at least one longitudinal opening extending therefrom to outer wall to allow placement of container on plant or to allow removal of container from plant. The container is configured with a plurality of geometrically shaped stakes of variable size extending therefrom the base portion for providing stability for apparatus to be secured in plant growing medium.

A system and method for irrigation, and managing irrigation of, a property or landscape. The system may include an irrigation management server (“IMS”) with the information for an irrigation system. The system may access the irrigation system that has been input into the IMS as well as access a third party map that may display the irrigation system over the map. The system may provide for a user's GPS location to be accessed through and identify the location of the user with respect to the map and irrigation overlay. The system display may provide information regarding the landscape to a user. The system may allow for manipulation of the irrigation system while overlaid on the map by the creation and manipulation of zones within the irrigation system as well as the creation and manipulation of other commands, including watering times and watering duration.

A sensor system includes a plant growth sensor, an environmental sensor device, and processing electronics. The plant growth sensor includes a strain sensor arranged on a first stretchable and flexible substrate. The environmental sensor device includes first and second environmental sensors arranged on a second stretchable and flexible substrate. The processing electronics are electrically coupled to the plant growth sensor and the environmental sensor device. The processing electronics include a wireless communication transceiver.

Soil moisture monitoring systems and methods for measuring mutual inductance of area of influence using radio frequency stimulus are disclosed herein. An example device includes a master element stacked vertically on top of one or more slave elements. The master element and slave elements can communicate through a 1-wire bus configuration. The master element can determine the presence and location of each of the one or more slave elements using an auto-discovery process. The master element can issue commands to the one or more slave elements to obtain moisture readings and/or temperature readings.

A submersible member can include an elongated body defining an outer body surface, the body defining a top end and a bottom end; a base electrode extending through the outer body surface; a first conductive member extending through the body from the top end to the base electrode, the first conductive member connected in electrical communication with the base electrode; an indicator electrode extending through the outer body surface, the indicator electrode positioned between the top end and the base electrode; and a second conductive member extending through the body from the top end to the indicator electrode, the second conductive member connected in electrical communication with the indicator electrode.

This application provides a dendrobium watering method and system, by way of imitation of wild cultivation of dendrobium on volcano, first on the volcano cant selection from the top 15 to 25 cm line code position, use a hard masonry nail line code insert to spray rod fixed to the fixed position of the line of code. The ground lance G-shaped nozzle is higher than the top of the volcano.

An approach to the prediction of soil density and subsoil crop growth may be provided. The approach may include subsoil sensor which can monitor changes in soil pressure and moisture conditions. The sensor data can be sent to a computer module which can process the data using a machine learning model predicting the soil density around a subsoil crop and the yield of the subsoil crop. A soil maintenance plan can be generated from the soil density prediction and/or the crop yield prediction. The soil maintenance plan can be sent to soil management robots, which can execute the soil maintenance plan.

Aeration and drying of subsurface soils with a subsurface irrigation system. An air inlet and bypass pressure regulator allow pressurized gas to be introduced into a zone of the system to aerate and dry a field. Pressurized gas or aerosolized agrochemicals are delivered through emitters integrated into the driplines within the system. Emitters integrated into the driplines allow aeration and drying of subsurface soils during times of season when high amounts of precipitation or localized flooding interfere with the systems use for irrigation.

An irrigation system and method of controlling operations of the irrigation system are provided. The irrigation system comprises a plurality of mobile support towers, a plurality of structural supports, a fluid-carrying conduit, water emitters, a sensor, and a control system. The plurality of mobile support towers are configured to move across a field. The plurality of structural supports extend between the mobile support towers, and the fluid-carrying conduit is supported above the field by the plurality of structural supports. The water emitters are coupled with the fluid-carrying conduit and emit water from the conduit onto the field. The sensor is supported on one of the structural supports or mobile support towers and is configured to capture data associated with a residue cover of a portion of the field. The control system is in communication with the sensor and is configured to receive the data associated with the residue cover of the portion of the field and determine a residue cover percentage for the portion of the field based on the data.
