1. Multi-functional plant fertilization programmer, containing a microprocessor circuit with an 8035 central unit in standard configuration, characterized in that to the microprocessor circuit (1) are connected two input and output ports (2, 3) of which one port (2), which serves the circuits for communication with the user, is coupled to informational segments (4-4e) which have digital displays and are activated by means of a changer (5) and driver (6), and that port is also coupled via a matrix (7) to informational buttons (8-8e) and functional buttons (9-9e) used for the implementation of the entire fertilization programme, while the second port (3) is coupled to the controller of the container valves (10), to a circuit (11) of demultiplexers and control units for the valves of particular fertilization functional sections, to the controller (12) of an injection pump, to a blocking system (13) for salt and acidity regulators, to a system of switches (14) for control of the dosing valve, to converters (15, 16) of the calibration signal translators (15a, 16a) of the salt and acidity regulators, and to the extractor (17) of the alarm control and blocking signal.<IMAGE>
