The invention relates to a complex solid biostimulant, to a process for preparing it and to a method for applying the same. According to the invention, the product comprises the following microelements: 11.1...20% nitrogen in ammonium, nitric, amidic and organic form, 11.1...15% phosphorus pentoxide, 10.5...11.5% potassium oxide, 27...44.7% organic substances, 8.5...15% organic carbon, 1.1...2.8% sulphur and 1.7...1.9% chelated microorganisms, the percentage being expressed by mass. The process, as claimed by the invention, consists in grinding, mixing and homogenizing the mono-ammonium phosphate, mono-potassium phosphate, potassium nitrate together with urea, an ethylenediaminotetraacetic acid salt, organic acids, organic substances with biostimulating effect and soluble salts of the following microelements: iron, copper, zinc, manganese, magnesium, molybdenum and boron. The claimed method consists of the foliar and/or radicular administration of the biostimulant product, as claimed, as aqueous solution in a concentration of 0.01...10%, by spraying, fertigation or drip irrigation, depending on the crop, vegetation stage and agrochemical characteristics of the soil. Invenţia se referă la un biostimulant complex solid, un procedeu de obţinere şi o metodă de aplicare a acestuia. Produsul, conform invenţiei, este constituit în procente masice din microelementele:11,1...20% azot sub formă amoniacală, nitrică, amidică şi organică, 11,1...15% pentaoxid de fosfor, 10,5...11,5% oxid de potasiu, 27...44,7% substanţe organice, 8,5...15% carbon organic, 1,1...2,8% sulf şi 1,7...1,9% microorganisme chelatate. Procedeul, conform invenţiei, constă în măcinarea, amestecarea şi omogenizarea fosfatului monoamoniacal, fosfatului monopotasic, azotatului de potasiu împreună cu uree, o sare a acidului etilendiaminotetraacetic, acizi organici, substanţe organice cu efect biostimulant şi săruri solubile ale microelementelor fier, cupru, zinc, mangan, magneziu, molibden şi bor. Metoda constă în administrarea produsului biostimulant, conform invenţiei, foliară şi/sau radiculară sub formă de soluţie apoasă de concentraţie 0,01...10% prin pulverizare, fertigare sau udare. cu picătura, în funcţie de cultură, fazele de vegetaţie şi caracteristicile agrochimice ale solului.
