Abstract
A chemical distribution system for use with a mobile irrigation system comprising a liquid chemical supply line vertically adjustably supported on the irrigation system and which is in operative communication with a pressurized source of liquid chemical. A liquid chemical distribution line is positioned beneath the chemical supply line between each pair of the drive towers for the irrigation system and which is in fluid communication with a remotely controlled, electrically operated solenoid valve which is in fluid communication with a chemical supply line. A plurality of spaced-apart emitter valves, having a sprinkler associated therewith, are provided on each of the distribution lines with the associated solenoid valve being operated by a control for activating selective distribution lines whereby liquid chemical may be applied to preselected portions of the area over which the irrigation system moves. An adjustable hydraulic accumulator is associated with each of the emitter valves to meter the amount of liquid chemicals being applied to the field.
