Novelty: method for the nutrition control of the trunk 26 and root region 12 of plants via electric current applied to the cultivated soil 17 or artificial soil substrates. Constitution: electronic circuit 6 for the control and generation of electric voltage and current, the lines (18, 10, 19) for the conveyance of the electric voltage and current, the switches 7, the control lines of these last (8,9) , the electrodes (11,12) and the groundings (3,4,5). Purpose: plant nutrition control; creation of useful elements from insoluble compositions; increase of the temperature of the root 12 and trunk 26; control of pathogenic micro-organisms; improvement of the breathing of the roots 12; upgrade of the properties of the soil 17 or substrate 20 and of the nutritional solution as well. Advantages: minimization of chemical fertilisers and toxic substances. Embodiment: in plant cultivations of great or small number of plants cultivated on soil 17 or on artificial substrates 20. |
