An irrigation system and method of controlling operations of the irrigation system are provided. The method includes determining, via a control system, a soil water depletion at a first location based on soil data captured via a sensor; determining, via the control system, a difference in irrigation amounts at the first location and a second location; determining, via the control system, a difference in precipitation amounts at the first location and the second location; determining, via the control system, a difference in evapotranspiration values of crops at the first location and the second location; calculating an estimated soil water depletion at the second location based, at least in part, on the soil water depletion at the first location, the difference in irrigation amounts at the first location and the second location, the difference in precipitation amounts at the first location and the second location, and the difference in evapotranspiration values of crops at the first location and the second location; and directing, via the control system, the irrigation system to apply an amount of water at the second location based, at least in part, on the estimated soil water depletion at the second location. The irrigation system may comprise a fluid-carrying conduit, a plurality of support towers with one or more controllable motors, water emitters, a controllable valve, and a control system that performs one or more of the aforementioned method steps.
