Abstract: A crop modeling system includes an irrigation system and a user input device coupled to the irrigation system. The irrigation system and the user input device are configured to communicate with a processor and non-transitory memory storing executable instructions. The executable instructions are configured to cause the processor to open a crop modeling graphical user interface for a geospatial location of a field associated with the irrigation system, move a crop graphical user interface element to a mapped location on the crop modeling graphical user interface responsive to one or more user inputs received via the user input device, generate an in-season crop model by applying the one or more user inputs to the crop model via the moving of the crop graphical user interface element, and generate one or more control signals based on the in-season crop model.

Abstract: A method of optimizing water applications of a center pivot irrigation system. The field is mapped to determine the yield potentials of various parts of the field. The field map is divided into sectors or zones and the yield potentials of those sectors or zones are determined. The number of sectors or zones to be irrigated is dependent upon the water flow available to the irrigation system. Only those sectors or zones which can receive adequate irrigating water to achieve the predetermined water application depth will be irrigated.

Abstract: A method is described for automatically adjusting the water application rate of an irrigation system which is movable over an agricultural field, comprising the steps of: (a) processing one or more main field layers of geospatial data; (b) generating variable irrigation management zones dependent on the irrigation system in the field; and (c) adjusting water application from the irrigation system dependent on the spatial location of the irrigation system in the field and the underlying processed geospatial field data previously determined. The method may also use the step of utilizing one or more of the field layers to identify at least one optional crop sensor location within the field. The water application rate is adjusted by increasing or decreasing the speed of the irrigation system or by turning the irrigation system on or by turning the irrigation system off.
