    Abstract: An apparatus and method is disclosed for the automatic injection of a liquid additive into a horticultural liquid dispensation system. The invention includes a programmable controller (20) and an injection assembly (50) comprising at least one solenoid valve (52, 54) and injector (70). The controller senses which of a plurality of watering zones is currently being watered, and effects the transmission of electrical pulses to the solenoid valve, causing the valve to open/close and thereby produce stroking of a spring-loaded piston (72) within the injector.

    Abstract: Disclosed is a proportioner for a fluid flow ( DOLLAR g(f)) from the inlet in a first proportioning element (10) to the outlet of a second proportioning element (10), characterized in that the first and second proportioning elements comprise a membrane (12) with one or more apertures (16) for detecting a pressure difference between the proportioner (10) inlet and outlet. The proportioner has a pressure transmitter for applying a pressure at the fluid inlet. The first and second proportioning elements (10) are mounted one after the other to allow a congestion or blocking of the resistance to flow provided at each membrane (12) to be detected due to the pressure fall in the membranes (12).
