The present invention concerns to a fertilization system that allows spraying a second product simultaneously with the first one, not requiring to repeat the process； with this purpose the system presents a mechanical support structure and a set of tanks (1, 2), taps and nozzles (4), which allow spraying of two products to be carried out simultaneously, although using different nozzles spaced a short distance from each other, in the order of centimeters. In addition to this double-spray, and in order to solve the lack of certain substances in specific land spots, the present invention allows the spraying being carried out in a heterogeneous way, through an intelligent system having as input georeferenced information of the land to be treated and by parameters entered by the user, i.e., in a certain area of the land it is possible to spray a certain amount of product, which may be different in another area.
