The aerator device includes a manifold including an interior channel, a connector aperture, and a plurality of nozzles configured to discharge a pressurized fluid stream. A cover plate is disposed on an upper side of the manifold. A first connector includes a first open end in fluid communication with the interior channel and a second end extending through a connector aperture disposed on an upper side of the cover plate. A second connector is configured to receive a hose connection to a pressurized fluid supply. A wheel including a wheel height adjustment mechanism is affixed to each side portion of the cover plate. In one embodiment, the manifold is configured to rotate when the wheels of the device rotate via a drive roller. A handle extending rearwardly from the cover plate includes a trigger mechanism configured to activate the flow of fluid from a pressurized fluid source.

Electric fluid flow monitoring apparatus, and agricultural fluid application systems and methods including the same are described. The fluid flow monitoring apparatus generally includes an outer housing defining a cavity. The outer housing includes an inlet for fluid to enter the cavity and an outlet for fluid to exit the cavity. Fluid flows through the cavity from the inlet to the outlet. The flow monitoring apparatus also includes an inner housing defining an interior cavity and positioned within the outer housing cavity such that fluid flows through the interior cavity. The inner housing is removably connected to the outer housing such that the inner housing is interchangeable with another inner housing having a different cross-sectional profile. The flow monitoring apparatus further includes a traveler movably disposed within the interior cavity.

Systems and methods for suppressing vaporization of a volatile fluid dispensed from a pressure vessel are provided. The system includes an evaporator coupled in thermal communication with a first flow of volatile fluid from the pressure vessel and in fluid communication with a second flow of volatile fluid from the pressure vessel. The evaporator includes at least one channel therein for channeling the second flow of volatile fluid therethrough. In addition, the system includes a compressor coupled in fluid communication with and downstream from the at least one channel. Moreover, the system includes a return line coupled in fluid communication with an outlet of the compressor. The compressor is configured to compress the second flow of volatile fluid and channel the compressed second flow of volatile fluid to the pressure vessel via the return line.

A plant watering system includes an irrigation mat that can be placed around a plant on top of the soil. The irrigation mat includes a water reservoir that holds water, and a slow-pass water permeable membrane that releases the water in the water reservoir in a slow manner so the soil around the plant is watered at a controlled rate. The irrigation mat may optionally include a threaded port where a container of liquid fertilizer can be placed so the liquid fertilizer is mixed with the water in the reservoir, allowing easily fertilizing the plant as it is watered. The plant watering system may also optionally include a dryness sensor that provides an alert indicating the water reservoir in the irrigation mat needs to be refilled.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

In one aspect, a planter row unit is provided an includes a frame, a first opener disc configured to open a seed trench, and a second opener disc configured to open a second trench different than the seed trench. The second opener disc is rotatable relative to the frame and is vertically moveable relative to the frame. In one aspect, an opener assembly is provided and includes a bracket, an opener disc coupled to the bracket and rotatable relative to the bracket and vertically moveable relative to the bracket, and a biasing member coupled to and between the bracket and the opener disc. The biasing member biases the opener disc vertically downward. In one aspect, a planter row unit is provided and includes an applicator support member made of a resilient material to allow movement of the applicator support member and inhibit deformation of the applicator support member.

Systems, methods and apparatus for monitoring soil properties and applying fertilizer during a planting operation. Various sensors are disposed in ground engaging components for monitoring soil properties. The ground engaging components may have structure for opening a side trench in the sidewalls of the seed trench and may include liquid application conduits for injecting liquid into the sidewalls of the resulting side trenches.

A calibration device that utilises sensor data from an optical sensor to develop one or more calibration parameters for controlling operation of a sprayer utilising itself optical sensors and transmitting the calibration parameters to said sprayer. A method of calibrating a sprayer utilising the calibration information is also disclosed. A method of pasture or crop management for a region of interest in which a composite representation of cumulative substance applications is used to developing a representation in which sub regions of the region of interest having prescribed characteristics are visually differentiated from other regions. The spatial distribution of calibration values may also be recorded and used to analyse substance application against calibration values to develop a report of apparently anomalous calibration values.

Seed sensors are present for determining seed placement in a furrow to then target at least one of fluid and solid application with respect to the seed. Plant sensors are present for determining location of plants within a field and then targeting at least one of fluid and solid application with respect to the plant.

A bracket for use with an agriculture planter including a trailing arm frame defining a pivot point thereon may include an arm bracket assembly with first and second arms. Each arm may extend from a middle portion of the bracket. First and second implements may be rotatably mounted on mounting ends of two of the arms. The middle portion of the bracket may be pivotally coupled to the trailing arm frame at the pivot point.
