A mobile irrigation system comprising: a conduit for carrying and dispensing water; at least one mobile tower for supporting and moving the conduit; and a computer for receiving information from a user and for controlling operation of the irrigation system, the computer programmed to: receive water application amount information from the user, receive water application pattern information from the user, automatically determine an irrigation plan using the amount information and the pattern information, operate the mobile irrigation system according to the irrigation plan by: moving the mobile irrigation system from a first position to a second position along a path, as the irrigation system moves from the first position to the second position, applying water from the irrigation system at a first application level at the first position and gradually decreasing the application level between the first position and the second position such that the water is applied at a second application level at the second position, the second application level being less than sixty percent of the first application level, moving the mobile irrigation system from the second position to the first position along the path, and as the irrigation system moves from the second position to the first position, applying water from the irrigation system at the first application level at the second position and gradually decreasing the application level between the second position and the first position such that the water is applied at the second application level at the first position. a conduit for carrying and dispensing water; at least one mobile tower for supporting and moving the conduit; and a computer for receiving information from a user and for controlling operation of the irrigation system, the computer programmed to: receive water application amount information from the user, receive water application pattern information from the user, automatically determine an irrigation plan using the amount information and the pattern information, operate the mobile irrigation system according to the irrigation plan by: moving the mobile irrigation system from a first position to a second position along a path, as the irrigation system moves from the first position to the second position, applying water from the irrigation system at a first application level at the first position and gradually decreasing the application level between the first position and the second position such that the water is applied at a second application level at the second position, the second application level being less than sixty percent of the first application level, moving the mobile irrigation system from the second position to the first position along the path, and as the irrigation system moves from the second position to the first position, applying water from the irrigation system at the first application level at the second position and gradually decreasing the application level between the second position and the first position such that the water is applied at the second application level at the first position. receive water application amount information from the user, receive water application pattern information from the user, automatically determine an irrigation plan using the amount information and the pattern information, operate the mobile irrigation system according to the irrigation plan by: moving the mobile irrigation system from a first position to a second position along a path, as the irrigation system moves from the first position to the second position, applying water from the irrigation system at a first application level at the first position and gradually decreasing the application level between the first position and the second position such that the water is applied at a second application level at the second position, the second application level being less than sixty percent of the first application level, moving the mobile irrigation system from the second position to the first position along the path, and as the irrigation system moves from the second position to the first position, applying water from the irrigation system at the first application level at the second position and gradually decreasing the application level between the second position and the first position such that the water is applied at the second application level at the first position. moving the mobile irrigation system from a first position to a second position along a path, as the irrigation system moves from the first position to the second position, applying water from the irrigation system at a first application level at the first position and gradually decreasing the application level between the first position and the second position such that the water is applied at a second application level at the second position, the second application level being less than sixty percent of the first application level, moving the mobile irrigation system from the second position to the first position along the path, and as the irrigation system moves from the second position to the first position, applying water from the irrigation system at the first application level at the second position and gradually decreasing the application level between the second position and the first position such that the water is applied at the second application level at the first position.
