Zusammenfassung:The invention relates to a composition of foliar liquid fertilizer and to a process for its preparation. According to the invention, the composition comprises, as macroelements: 70...112 g/l total nitrogen, 31...80 g/l soluble phosphorus, 36...80 g/l water-soluble potassium, 5...20 g/l glycyl betaine from natural sources, as microelements: 0.35...0.45 g/l iron, 0.33...0.40 g/l manganese, 0.15...0.22 g/l copper, 0.10...0.15 g/l magnesium, 0.04...0.08 g/l zinc, 0.018...0.023 g/l molybdenum, 0.04...0.07 g/l selenium, conditioning adjuvants: 10...150 g/l glycerine and/or polyols and water-soluble and fat-soluble surface-active substances, as well as 0.35...0.7 g/l salicylic acid and deionized water. The claimed process consists in preparing a microbiogically-stable solution by diluting, with deionised water, a standardized vinasse resulting from bakery yeast production or molasses resulting from sugar production, having a content of 5...20% glycyl-betaine and adding salicylic acid, preparing the macroelements solution and the microelements solution, whereto conditioning adjuvants are added, after which it is added over the macroelements solution, while continuously stirring, to result in a solution of liquid fertilizer which is recirculated through a homogenization system under pressure for stabilization. Invenţia se referă la o compoziţie de îngrăşământ lichid foliar şi la un procedeu de obţinere a acesteia. Compoziţia, conform invenţiei, conţine ca macroelemente: 70...112 g/l azot total, 31...80 g/l fosfor solubil, 36...80 g/l potasiu solubil în apă, 5...20 g/l glicil-betaina din surse naturale, ca microelemente: 0,35...0,45 g/l fier, 0,33...0,40 g/l mangan, 0,15...0,22 g/l cupru, 0,10...0,15 g/l magneziu, 0,04...0,08 g/l zinc, 0,018...0,023 g/l molibden, 0,04...0,07 g/l seleniu, adjuvanţi de condiţionare: 10...150 g/l glicerină şi/sau polioli, respectiv substanţe tensioactive hidrosolubile şi liposolubile, precum şi 0,35...0,7 g/l acid salicilic şi apă deionizată. Procedeul, conform invenţiei, constă în realizarea unei soluţii microbiologic stabile prin diluarea cu apă deionizată a vinasei standardizate rezultată la producerea de drojdie de panificaţie sau melasă rezultată la producerea zahărului având un conţinut de 5...20% glicil-betaină şi adăugarea de acid salicilic, realizarea soluţiei de macroelemente, respectiv, de microelemente în care se adaugă adjuvanţi de condiţionare şi se adaugă peste soluţia de macroelemente, sub agitare continuă, rezultând o
