A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump has a frame, a fluid conduit coupled to the frame, a housing located at a bottom end of the liquid manure pump configured to be immersed in a liquid manure reservoir, a combiner for creating a liquid manure connection between at least two liquid manure outlets of the housing and the fluid conduit. an impeller located within the housing, a drive shaft connected to the impeller, and an agitator nozzle, in fluid communication with at least one of the liquid manure outlets, for directing a portion of the liquid manure outwardly from the pump.

A nozzle for dispersing liquids having a housing with a liquids inlet, an exit chamber, and first, second and third exit ducts which proceed from the exit chamber. A longitudinal axis of the first exit duct lies in a central plane of the housing, a longitudinal axis of the second exit duct is disposed at a second angle to the central plane, and a longitudinal axis of the third exit duct is disposed at a third angle to the central plane. The third angle in terms of the value being identical to the second angle but in terms of the algebraic sign being different therefrom. A free cross section of the second exit duct and a free cross section of the third exit duct are dissimilar such that in the operation of the nozzle dissimilar quantities of liquid are discharged from the second exit duct and the third exit duct.

In an example, an agricultural slurry is applied to a field, for instance to change a constituent profile of the soil. For instance, a slurry application system includes a slurry applicator configured to apply the agricultural slurry. In another example, characteristics of the agricultural slurry are determined with a sensor. The characteristics of the agricultural slurry are compared with corresponding application thresholds. In yet another example, a slurry application controller cooperates with the slurry applicator or a prime mover to apply the agricultural slurry based on the comparison.

A fertigation system comprises: a controller that transmits sensor data to a fertigation control server, and that controls a water supply valve, a culture stock solution supply valve, and a discharge valve on the basis of received data; and a fertigation control server that, on the basis of the sensor data received from the controller, calculates control amounts for the water supply valve, the culture stock solution supply valve, and the discharge valve, and returns the control amounts to the controller.

A robotic sprayer for optimizing application of crop related materials, comprising one or more imaging sensors, one or more nozzles configured for spraying one or more materials, one or more actuators configured for moving the one or more nozzles, and one or more controllers. The controller(s) is configured for receiving imagery data captured by the imaging sensor(s) depicting one or more plants, computing a foliage model modeling a foliage of the plant(s) based on analysis of the imagery data, identifying, based on analysis of the foliage model, one or more access courses to one or more underlying parts of the plant(s) which are at least partially covered by the foliage, operating the actuator(s) to adjust in real-time a position of the nozzle(s) according to the access course(s), and operating the nozzle(s) to spray the material(s) over the underlying parts.

A work vehicle includes an implement coupled to the work vehicle. A global positioning system is communicatively coupled to the work vehicle and is configured for generating a location signal indicative of a location of the work vehicle. At least one sensor is communicatively coupled to the work vehicle and configured for generating first and second sentinel plant characteristic signals indicative of first and second sentinel plant characteristics. A control system is communicatively coupled to the work vehicle and configured to receive the location signal, the first and second sentinel plant characteristic signals, determine an implement action based on a function including the first and second sentinel plant characteristics as variables, and control the implement to execute the implement action in the field.

In one embodiment, a method includes metering agricultural product to a first header of an agricultural implement via a first meter module of a metering subassembly, receiving, at a processor, a first signal indicative of a first amount of agricultural material at the first header, and determining, via the processor, a first time relative to activation of the first meter module when the first amount reaches a target amount of agricultural product based at least in part on the first signal.

An automated steering system for an agricultural vehicle operating in a row crop field. The automated steering system includes a correction system having a controller and an alignment sensor. The alignment sensor is disposed between two adjacently spaced crop rows and generates output signals indicative of the alignment sensor's lateral position relative to the two adjacently spaced crop rows as the vehicle advances in the forward direction of travel. The controller receives the generated output signals from the alignment sensor and determines an offset distance of said alignment sensor from a centerline between the two adjacently spaced crop rows. The controller outputs a modified vehicle position signal corresponding to the latitude and longitude position received from said GPS receiver shifted by the offset distance. The vehicle's on board navigation controller causes the vehicles on-board steering control system to steer the vehicle based on the modified vehicle position signal.

A pump is provided for immersion in a fluid reservoir, such as a pit or lagoon containing liquid manure, from a position at an edge of the reservoir. The pump may be adapted for connection to a farm vehicle, such as a tractor, positioned at the edge of the reservoir. The pump comprises an extensible body, fluid conduit and drive means in order that a length of the pump may be varied in order to accommodate a variety of reservoir fluid heights. In addition, the pump may be pivotable relative to at least a portion of a frame in order that the entrance angle may be adjusted. The pump may comprise a housing with an inlet and an outlet, the outlet in fluid communication with the fluid conduit. An impeller within the housing may direct fluid from the inlet to the outlet in the housing.
