Abstract: An automatic or semiautomatic device for the controlled metering and mixing of a plurality of active liquid substances for plants, includes elements for selectively sampling the substances in corresponding containers and moreover includes a fluid transfer element and, elements for metering, mixing, and diluting the sampled or transferred amounts of the liquid substance(s). The device also includes a controlling and managing unit that controls the sampling and transferring element and is associated with measurement elements and an element for controlling the flow of fluids within the valve-type device. The measurement elements include an element, advantageous for sequential use, for measuring a basic volume of a sampled concentrated liquid substance, the volume needing to be mixed and/or diluted.
