FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. The method of producing fertiliser from lignocellulose material, which involves treatment of starting material by crushing with simultaneous exposure to heat and pressure of 3-50 MPa, wherein treatment is carried out in a mixer with shearing stress of 0.03-3 N/mm2 at temperature 130-150°C in the presence of lime Ca(OH)2, which is fed in amount of 2-10% of absolutely dry lignocellulose material and at least one layer in amount of 3-10% of absolutely lignocellulose material, with moisture content of the lignocellulose material not less than 20%, wherein the lignocellulose material used is bulrush and/or grass and/or straw and/or sawdust and/or peat.
EFFECT: invention enables to obtain organomineral fertiliser with different content of humic substances and widens the raw material base.
