The invention relates to a fertiliser that has a mass fraction of ammonium sulphate, a mass fraction of ammonium nitrate and a mass fraction containing calcium carbonate, a carbonate or a hydrogen carbonate of magnesium or calcium. The mass fraction of calcium carbonate or a carbonate or a hydrogen carbonate of magnesium or calcium is at least 1,5 mass % and the mass fraction of ammonium sulphate is at least 5 mass % of the fertilizer. The invention also relates to a method for producing a fertilizer, wherein a melt or solution of ammonium nitrate and ammonium sulphate is mixed with calcium carbonate in a mixing device and subsequently, the fertilizer is obtained by granulating the suspension containing the calcium carbonate. |
