Abstract:
1. A portable lightweight low pressure soil treatment applicator for a home, lawn or garden irrigation system with predefined areas of soil to be irrigated using a pressurized water supply and pressurized water for irrigation, wherein the portable lightweight low pressure soil treatment applicator comprising: a. a housing comprising: b. a programmable logic circuit installed in the central cavity, comprising: c. a reservoir in the central cavity fluidly connected to the chemical inlet port for receiving a liquid soil treatment solution from a chemical source, the reservoir comprising: d. a suction check valve fluidly connected to the container outlet; e. a low pressure chemical pump electrically connected to the programmable logic circuit and fluidly connected to the suction check valve, the low pressure chemical pump increases pressure of the liquid soil treatment solution to form a pressurized liquid soil treatment solution, wherein the pressurized liquid soil treatment solution has a pressure which is at least 10 percent greater than the pressure of the pressurized water supply; f. a mixing chamber for receiving the pressurized liquid soil treatment solution from the low pressure chemical pump, and for mixing with pressurized water from the water inlet port until the pressurized liquid soil treatment solution is diluted to a preset ratio forming the diluted pressurized liquid soil treatment solution; and g. a discharge check valve between the mixing chamber and the low pressure chemical pump for directionally controlling flow of the pressurized liquid soil treatment solution to the mixing chamber and preventing pressurized water from moving into the low pressure chemical pump; and
