A module for measuring and monitoring an inlet and outlet pressure is described herein. The module includes an inlet pressure port for fluid communication to a fluid line before a filter and the inlet pressure port comprising a first pressure sensor. The module includes an outlet pressure port for fluid communication to a fluid line after the filter and the outlet pressure port comprising a second pressure sensor. At least one signal port is disposed in the module. The first pressure sensor and the second pressure sensor during operation are in signal communication with the at least one signal port.

A ball valve assembly having a valve body with a single inline fluid passage therethrough along a central longitudinal axis. A ball valve is sealingly seated in a valve seat within the valve body. The ball valve includes at least two through-bores, each of the at least two through-bores having a central axis intersecting one another, whereby the ball valve is rotatable between a fully open position and a fully closed position. In one application, the ball valve has two bores intersecting one another such that an angle α between adjacent bore openings of the ball valve are less than 90 degrees and an angle β between other adjacent ends of the ball valve are greater than 90 degrees for applying liquid product in a seed furrow before and after each seed in the furrow but not onto the seed.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

A system (100) for testing an agricultural implement includes a frame (106) configured to receive a device (104) to be tested. The frame carries a filter (108), a pump (112), a pressure relief valve (116) in fluid communication with the pump outlet, a frame output tube (122) to deliver the flow of fluid from the pump outlet to the device to be tested, a frame return tube (124) to receive the flow of fluid from the device to be tested, and a recycle flow outlet (128). A method of testing includes connecting a device to the frame output tube and the frame return tube, pumping a fluid from the frame output tube to the frame return tube through the device, and measuring a flow rate of the fluid through the device.

The invention relates to a distribution device (1) for a slurry containing liquid and solid constituents, comprising: a housing (2) with an inlet (6) for the slurry, an end wall (4) at the driving side, an opposite further end wall (5) and multiple outlets (7) at at least one of the two end walls (4, 5) for distributing the slurry, a rotor (40), which is arranged in the housing (2) and rotatable about a rotation axis (10) and comprises at least one blade arrangement (60) for sweeping over the outlets (7) at the inside of the housing and an air distribution chamber (45) for distributing compressed air to the blade arrangement(s) (60), a driving unit (20) with a motor (26), which is arranged outside of the housing (2), and a driving shaft (22), which is coaxial to the rotation axis (10), passes through the end wall (4) at the driving side and is connected to the rotor (40) in a rotationally fixed manner, and an annular air transmission chamber (51), which passes through the end wall (4) at the driving side and is arranged coaxially with the rotation axis (10) and radially outside of the driving shaft (22), wherein the air transmission chamber (51) is connected to an air inlet (27) at the outside of the housing for compressed air and to the air distribution chamber (45) at the inside of the housing in an air-conducting manner.

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.
