Abstract

For the purpose of having it licensed in Romania, the Folhum fertilizer was tested in the vegetation house and in field, with the result of a distinctly significant yield increase. The liquid fertilizer was obtained by neutralizing phosphoric acid of 85% concentration with potassium carbonate of 98% concentration. The reaction took place under permanent stirring at the temperature of 250- ���E&�� DQGE\� JUDGXDOO\� DGGLQJDVRXUFHRIQLWURJHQ� �DPLGLF�� QLWULFDQGDPPRQLDFDO��� DVROXWLRQRI� microelements (Fe, Cu, Zn, Mg, Mn, B) chelated with Na2EDTA and a solution of potassium humate. Potassium humate was extracted from lignite with a potassium carbonat solution. Experiments were organized in three climatic areas, vegetation house, greenhouse and field, in the Teleorman and Iasi districts. The experimental fertilizer application provided increases of the yield by 45.5% in the Dacia Pontica tomato and 49.2% in the Justin sunflower in vegetation house, as compared to the control to which foliar fertilizer was not applied. The application of Folhum in field increased by 14.4% the yield of sunflower with basic fertilization 80 kg N/ha, 80 kg P2O5 /ha, as compared to the control alternative to which foliar fertilizer was not applied. It increased the yield of tomato hybrid ADI 7 grown in the greenhouse with drip irrigation on a non-fertilized soil by 38.5%, and by 34.9% WKHJUDSH�\LHOGLQD�&KDVVHODV�'RUpYDULHW\�YLQH� culture. All yield increases were statistically significant at P<5%. Based on these increases, the fertilizer was authorized as RO-FERTILIZER and it may be used in Romania.
