ABSTRACT OF THE DISCLOSURE The production of a fertilizer from tree bark is im- proved by a process wherein crushed waste bark is treated toge- ther with waste molasses under elevated pressure and at a tem- perature of 75 to 140°C for a time of 10 min to 2 hours, said time being dependent on the treatment temperature. The improve- ment comprises adding yeast to the waste molasses, and maintain- ing its temperature at 30 to 40°C for 35 to 45 hours, whereby its pH value decreases to 3-4, before it is mixed with the ground waste bark.
