## Abstract

Systems and methods for scheduling and coordinating applications of fertilizers, pesticides, and water to fields while avoiding interferences between vehicles and other equipment may be implemented with a mobile irrigation system, a fertilizer applicator, a pesticide applicator, and a processing system. The processing system schedules and coordinates applications of fertilizers, pesticides, and water and prevents interferences between the machines primarily with data received from an irrigation schedule implemented by the irrigation system and data received from the fertilizer and pesticide applicators.

## Claims

### Claim 1

A method of scheduling and coordinating applications of fertilizers, pesticides, and water on crops in a field, the method comprising:
accessing data from an irrigation schedule with a processing system in communication with a control system of an irrigation system, the irrigation schedule including instructions for scheduling applications of water to the field;
accessing data from a fertilizer schedule with the processing system;
accessing data from a pesticide schedule with the processing system;
determining with the processing system a coordinated water/fertilizer/pesticide application schedule that indicates when to apply water, fertilizers, and pesticides to the field based on the data from the irrigation schedule, the fertilizer schedule, and the pesticide schedule;
receiving at the processing system location data representative of a location of the mobile irrigation system;
receiving at the processing system location data representative of a location of a fertilizer applicator;
receiving at the processing system location data representative of a location of a pesticide applicator;
determining with the processing system when the fertilizer applicator may enter the field and apply fertilizers to the field based on the coordinated water/fertilizer/pesticide application schedule, the location of the mobile irrigation system, and the location of the pesticide applicator; and
determining with the processing system when the pesticide applicator may enter the field and apply pesticides to the field based on the coordinated water/fertilizer/pesticide application schedule, the location of the mobile irrigation system, and the location of the fertilizer applicator.

### Claim 2 (depends on 1)

The method as set forth in claim 1, wherein the fertilizer schedule includes data representative of a planned route of the fertilizer applicator in the field while applying fertilizers to the field.

### Claim 3 (depends on 1)

The method as set forth in claim 1, wherein the pesticide schedule includes data representative of a planned route of the pesticide applicator in the field while applying pesticides to the field.

### Claim 4 (depends on 2)

The method as set forth in claim 2, further comprising determining with the processing system whether the location of the fertilizer applicator or the planned route of the fertilizer applicator will interfere with operation of the mobile irrigation system; and instructing the fertilizer applicator to not enter the field or to exit the field if the processing system determines the location of the fertilizer applicator or the planned route of the fertilizer applicator will interfere with operation of the mobile irrigation system.

### Claim 5 (depends on 3)

The method as set forth in claim 3, further comprising determining with the processing system whether the location of the pesticide applicator or the planned route of the pesticide applicator will interfere with operation of the mobile irrigation system; and instructing the pesticide applicator to not enter the field or to exit the field if the processing system determines the location of the pesticide applicator or the planned route of the pesticide applicator will interfere with operation of the mobile irrigation system.

### Claim 6 (depends on 1)

The method as set forth in claim 1, further comprising determining with the processing system whether the fertilizer applicator and the pesticide applicator are likely to interfere with one another based on the location of the pesticide applicator and the location of the fertilizer applicator.

### Claim 7 (depends on 6)

The method as set forth in claim 6, further comprising instructing the fertilizer applicator and the pesticide applicator to both stop if the processing system determines the fertilizer applicator and the pesticide applicator are likely to interfere with one another.

### Claim 8 (depends on 1)

The method as set forth in claim 1, wherein the mobile irrigation system is a center pivot irrigation system or a lateral move irrigation system.

### Claim 9 (depends on 1)

The method as set forth in claim 1, wherein the fertilizer schedule is stored in memory accessible by a control system of the fertilizer applicator.

### Claim 10 (depends on 1)

The method as set forth in claim 1, wherein the pesticide schedule is stored in memory accessible by a control system of the pesticide applicator.

### Claim 11 (depends on 1)

The method as set forth in claim 1, wherein the fertilizer applicator is an autonomous or semi-autonomous tractor, sprayer, spreader, or truck.

### Claim 12 (depends on 1)

The method as set forth in claim 1, wherein the pesticide applicator is an autonomous or semi-autonomous tractor, sprayer, spreader, or truck.

### Claim 13 (depends on 1)

The method as set forth in claim 1, wherein the processing system is incorporated in the control system of the irrigation system.

### Claim 14 (depends on 1)

The method as set forth in claim 1, wherein the processing system and the control system of the irrigation system are mounted on the mobile irrigation system or mounted remotely from the mobile irrigation system.

### Claim 15

An irrigation system comprising:
a series of mobile towers each having wheels and a motor for driving the wheels;
support structure for connecting the mobile towers to each other;
a water-carrying conduit supported by the support structure;
a plurality of water emitters connected to the conduit for delivering water to a ground surface;
a plurality of valves for controlling water flow to the water emitters;
a control system for controlling operation of the motors and the valves in accordance with an irrigation schedule to move the irrigation system over a ground surface and to apply selected amounts of fluids to the ground surface; and
a processing system in communication with the control system, the processing system programmed to
access data from the irrigation schedule;
receive data from a fertilizer schedule;
receive data from a pesticide schedule;
determine a coordinated water/fertilizer/pesticide application schedule that indicates when to apply water, fertilizers, and pesticides to the field based on the data from the irrigation schedule, the fertilizer schedule, and the pesticide schedule;
receive location data representative of a location of the mobile irrigation system;
receive location data representative of a location of a fertilizer applicator;
receive location data representative of a location of a pesticide applicator;
determine when the fertilizer applicator may enter the field and apply fertilizers to the field based on the coordinated water/fertilizer/pesticide application schedule, the location of the mobile irrigation system, and the location of the pesticide applicator; and
determine when the pesticide applicator may enter the field and apply pesticides to the field based on the coordinated water/fertilizer/pesticide application schedule, the location of the mobile irrigation system, and the location of the fertilizer applicator.

### Claim 16 (depends on 15)

The irrigation system as set forth in claim 15, further comprising a wireless data transceiver coupled with the processing system for wirelessly receiving the fertilizer schedule, the location data from the fertilizer applicator, the data from the pesticide schedule, and the location data from the pesticide applicator.

### Claim 17 (depends on 15)

The irrigation system as set forth in claim 15, wherein the processing system is incorporated in the control system of the irrigation system.

### Claim 18 (depends on 15)
