SYSTEM FOR DECREASING THE DROUGHT IMPACT IN THE PERFORMANCE OF A CULTURE, METHODS FOR PREPARING THE COMPONENT I OF THE SYSTEM, METHOD FOR DECREASING THE DROUGHT IMPACT ON THE PERFORMANCE OF A CULTURE USING SUCH SYSTEM AND THE AGRICULTURAL TOOL BEING USED THEREIN

System for decreasing the impact of drought on the performance of a culture, comprising: a component I that is a liquid fertilizer of radicular or foliar absorption that provides protons (H+), enzymatic, activator micro elements and, optionally, nitrogen (N) or nitrogen and phosphorus (N, P) or nitrogen, sulphur, glucose, and L-tirosine as metabolic activator (N, S); and a component II which is a group of electrodes that generates an electric current that provides electrons (e^-) of radicular absorption. Methods for preparing the component I, the component I (N), the component I (N, P) and the component I (N, S). Method for decreasing the impact of drought on the performance of a culture using the system previously described and the agricultural tool to be used in the step a) of said method.
