The invention relates lo a method for producing sulphurous nitrogen fertilizer, said method being characterized in that calcium nitrate is reacted with a sulphurous compound in a mixing device, and the fertilizer is obtained by the granulation of the gypsum-containing suspension formed. The invention also relates to a device for carrying out said method. In this way, a technically simple method for producing sulphurous nitrogen fertilizer can be provided due to the fact that the gypsum-containing suspension formed by the reaction is highly fluid and thus easy to pump, and can be treated in conventional granulation devices. The inventive method can also be earned out without the technically complex separation of precipitated gypsum. |
