Liquid nitrogen fertilizer (28%) + Sulfur (5%) Being guided by innovative thinking and trying to impose liquid nitrogen feeding in Bulgaria as the main one, we would like to present to you another product of the range of liquid fertilizers, which will fully change your idea of precise nitrogen feeding of plants. This is liquid nitrogen fertilizer with sulphur (UAN (urea and ammonium nitrate) + S). Liquid nitrogen feeding This product combines the positive qualities of three various nitrogen fertilizers – ammonium nitrate, urea and ammonium thiosulfate; all the advantages of the liquid nitrogen fertilizer in combination with sulphur. This makes it a unique product which may provide the best start for each crop. It is applicable not only in mass field crops but also at the vegetable production, the perennial plants, the vineyards and so on. The availability of the three forms of nitrogen in the combination with sulfur is not its main advantage. Ammonium thiosulfate acts as an inhibitor of the nitrification processes and in this manner the release of nitrogen is delayed and may last from 8 to 12 weeks. This makes it the best solution for pre-sowing fertilization of field crops.
