ABSTRACT:
The present invention relates to a method for producing fertilizer from softwood bark and/or tree waste in which the softwood bark is decomposed at a temperature of 70.degree. . . . 140.degree. C., when the protective substances detrimental to plants can be eliminated. Bark or tree ash is added to the ground bark mass in high pressure along with urea and, if necessary, with phosphorus and the product is finally granulated. Peat is added to the bark mass at the first stage of the process in order to increase granulation capacity and nutrient storage capacity. The decomposition temperature depends on the age of the mass. All urea is added in the end of the process in order to avoid the danger of toxicity.
