PROBLEM TO BE SOLVED: To provide a method capable of simply granulating black soil and further capable of obtaining a several kinds of granulated black soil by one production process and to provide black soil granulated by the method. SOLUTION: The method for producing the granulated black soil comprises a step for applying black soil to a first sieve, a step for drying the black soil, a step for adding 1-2 wt.% carbon to the dried black soil and mix both components under stirring, a step for adding 1-5 wt.% water-soluble polymer to the black soil to which carbon is added and mixing both components under stirring to granulate the black soil, a step for drying the granulated black soil, a step for applying granulated black soil passed through the drying step to a second sieve, a step for applying granulated black soil applied to the second sieve to a third sieve and a step for applying the granulated black soil applied to the third sieve to a fourth sieve.
