Method of obtaining a liquid organic biofertilizer for soil and/or plants, the biofertilizer and methods of using the same

A method of obtaining a liquid organic biofertilizer for soils or plants that is colonized by natural soil microorganisms, the method comprising:

• a) preparing, sorting and crushing a portion of a starting humus-containing soil or soil mixture, the starting humus-containing soil or soil mixture having an organic carbon in an amount greater than 10% and an organic nitrogen in an amount greater than 1% and having colonies of natural soil microorganisms, the colonies of natural soil microorganism having a concentration in the starting humus-containing soil or soil mixture being equal to or greater than 104 CFU/ml;
• b) mixing the crushed portion of the soil or soil mixture with water to produce a water suspension;
• c) creating a running flow of the water suspension within a closed circuit with restricted access to oxygen;
• d) cyclic processing of the running flow of the water suspension within the closed circuit with restricted access to oxygen by using a turbulence effect so as to preclude cavitation and to provide crushing solids in a processed medium of the running flow of the water suspension, and uniform heating of an entire volume the processed medium with a temperature growth rate not exceeding 2° C./min;
• the cyclic processing comprising at least a first stage and a second stage, wherein:
• the first stage includes providing an initial heating of the processed medium, extracting of carbon- and nitrogen-containing substances from the processed medium, transiting the substances into water-soluble forms with simultaneous crushing solids in the processed medium and obtaining a homogeneous processed medium with carbon- and nitrogen-containing substances in water-soluble forms causing a growth of colonies of natural soil microorganisms being present in the homogeneous processed medium, and by reaching a predetermined final temperature upon the initial heating the growth of colonies of the natural soil microorganisms present in the starting humus-containing soil is achieved with a concentration exceeding 108 CFU/ml and a uniform colonization of the homogeneous processed medium with carbon- and nitrogen-containing substances in water-soluble forms by these microorganisms is achieved;
• second stage includes providing a further heating of the homogeneous processed medium and a further crushing solids in the homogeneous processed medium to result in a hardening of the natural soil microorganisms present in the homogeneous processed medium, transiting the microorganisms into a state of anabiosis and spore form, and crushing solids in the homogeneous processed medium to a size ranging between 10 and 50 microns;
• and
• e) removing the homogenous processed medium from the closed circuit after finishing the second stage followed by a cooling of the medium to obtain a liquid organic biofertilizer, the liquid organic biofertilizer containing carbon- and nitrogen-containing substances in water-soluble forms, solids with a size of 10-50 microns and the hardened natural soil microorganisms present in the state of anabiosis or spore form and in the concentration exceeding 107 CFU/ml.
