Abstract: An agricultural implement including a frame, a plurality of ground engaging tools connected to the frame, a fertilizer device configured for applying at least one liquid fertilizer and including a plurality of fluid lines and a plurality of fertilizer applicator assemblies fluidly connected to the plurality of fluid lines. Each fertilizer applicator assembly includes an applicator connected to the frame and a valve fluidly connected to the applicator. The valve is configured for varying a rate of the at least one liquid fertilizer through the applicator. The agricultural implement also includes an electronic control unit operably connected to the valves of the plurality of fertilizer applicator assemblies and configured for automatically adjusting the valve of at least one fertilizer applicator assembly of the plurality of fertilizer applicator assemblies to vary the rate of the at least one liquid fertilizer, dependent upon a fertilizer requirement characteristic.
