The invention relates to a foliar fertilizer, a process and an installation for preparing the same. According to the invention, the fertilizer comprises an extract from Coriandrum sativum and Foeniculum vulgaris, nutritive elements: N, K, P, Ca, Mg and S, oligoelements: B, Cu, Fe, Mn, Zn, S and phytohormones, as well. The process, as claimed by the invention, comprises the successive stages of plant grinding, dosing and multiple extraction with an ethanol/water solution, separation by centrifugation resulting in a residue to be used as a fertilizer and an ethanolic extract to be conditioned in a manner known per se. The claimed installation comprises a zone () consisting of a conditioning reactor () provided with a stirrer () in which the dosed organic and inorganic components are introduced together with the water heated to 20...25°C taken from a zone (), the ethanolic extracts taken from two symmetrical zones () connected in cascade, measuring apparatuses, buffer vessels, vessels for storing the extraction residue and for discharging the fertilizer to a packing unit. |
