Abstract:
1. Chemical injection apparatus for use with an irrigation assembly of the type having a main water supply line with a plurality of zone lines, the zone lines having spray heads, a valve coupling each zone line to the main water supply line, a solenoid coupled to each valve, a first electronic processor for individually controlling the solenoids, the chemical injection apparatus comprising: a plurality of reservoirs for fertilizer chemicals and pest control chemicals; chemical lines coupling the reservoirs to the main water supply line; a chemical pump for each reservoir to feed chemicals from the reservoirs to the main water supply line; and a second electronic circuit board and programmable microprocessor for individually controlling the chemical pumps and for individually controlling the solenoids with their valves for chemical injection purposes, the first programmable irrigation electronic processor being coupled to the second electronic circuit board, whereby control signals from the first programmable irrigation electronic processor pass through the second electronic circuit board and then connect to the irrigation solenoids, the apparatus takes control of the irrigation system and runs it by controlling the irrigation zonal solenoids and simultaneously running chemical pumps.
