The present invention provides a system and method for calculating the water flow rates applied by corner arm sprinklers. According to a first embodiment, the present invention provides a system and method for controlling and balancing the flow rates of corner arm sprinklers to provide targeted discrete, controlled uniform and non-uniform water distribution rates across a given field.

Embodiments for crop-specific automated irrigation of an environmental medium and management of nutrients therein. In one aspect, operation of an irrigation apparatus can be regulated according to specific water demand of a crop. The water demand can be assessed by evaluating water content conditions of the environmental medium comprising the crop, medium characteristics, and/or nutrient delivery and transport characteristics at the medium. Regulation of operation of the irrigation apparatus can comprise control of one or more of water supply to the apparatus, positioning and/or movement of the irrigation apparatus, or configuration of sensing devices for collection of information suitable for such regulation.

A greaseless pivot center swivel and bearing device includes an outer housing having a sidewall with top and bottom portions, a top plate coupled with the top portion that includes an opening therein, and a bottom plate coupled with the bottom portion that includes an opening therein. The sidewall cooperates with the top and bottom plates to define an interior volume. A single, unitary bushing member formed of a low-friction material is positioned within the interior volume and includes a surface cylindrically curved about an axis extending between the top and bottom plates of the housing. The cylindrically curved surface cooperates with the openings in the top and bottom plates to define a cylindrical passage through the interior volume sized and shaped for receiving a cylindrical tube that rotates therein, e.g., a tube configured to connect with a water supply column of a mechanized irrigation system.

A mobile tower for use with an irrigation system comprises a frame, first and second spindles, a first height adjustment assembly, and a second height adjustment assembly. The frame is configured to support a fluid-carrying conduit of the irrigation system. The first and second spindles each include a generally upright beam. The first height adjustment assembly is rigidly connected to a first side of the frame and movably coupled to the first spindle. The first height adjustment assembly includes a first mechanism configured to raise or lower the first side of the frame relative to the first spindle. The second height adjustment assembly is rigidly connected to a second side of the frame and movably coupled to the second spindle. The second height adjustment assembly includes a second mechanism configured to raise or lower the second side of the frame relative to the second spindle.

According to a preferred embodiment, the system of the present invention may include a gearbox which includes a worm drive and a reduction assembly. According to a preferred embodiment, the worm drive preferably includes a worm shaft, a worm, a first gear wheel, and a first wheel shaft. Preferably, the worm shaft and the first wheel shaft are oriented orthogonally to each other. According to a further preferred embodiment, the worm drive of the present invention is preferably a double enveloping worm drive with the worm and the first gear wheel each being throated, mated and fully enveloped gears.

A system and method for determining specific prescriptions for targeted areas/plants within given irrigation areas. According to preferred embodiments, the system may use imaging data in combination with other sensors and analysis modules to identify selected pests and diseases affecting given crops. Preferably, the system may use machine learning/AI modules to analyze the data and to provide targeted prescriptions for targeted groups of identified crops based on identified conditions of infestation and/or disease within the identified crops.

The present invention relates generally to a system and method for detecting and adjusting the position of an irrigation span. More particularly, the present invention provides a system and method for detecting and removing deflection stresses from irrigation spans caused by corner arm positioning.
