FIELD: agriculture.
SUBSTANCE: inventions relate to agriculture. Solid fertilizer in the form of discrete particles, where each particle of solid fertilizer contains an inorganic material containing at least one of the nutrients N, P, K or S, where the inorganic material is selected from one or more liquid and solid inorganic fertilizers, including ammonium sulfate, APP (ammonium polyphosphate), NPP (nitrogen, phosphorus, potassium), NO3 PK, SOA (ammonium sulfate), MAP (monoammonium phosphate), DAP (diammonium phosphate), urea, CAN (ammonium calcium nitrate), MOR (potassium chloride), SOP (potassium sulfate), and heated organic material or torrefied organic material, while inorganic material and the heated organic material is evenly distributed over each of the particles, or the inorganic material and organic material are formed as a homogeneous mixture, and the carbon in the fertilizer is predominantly labile carbon, the fertilizer essentially does not contain carbon of biochar. A method for producing solid fertilizer in the form of discrete particles. A method for fertilizing a field in one pass during the growing season.
EFFECT: present inventions enable to produce an improved composition of fertilizer.
