FIELD: mineral fertilizers. ^ SUBSTANCE: invention relates to a method for conditioning mineral fertilizers. Composition for conditioning mineral fertilizers comprises active component based on primary aliphatic amines, hydrocarbon solvent, modifying agent for fluidity loss representing solid hydrocarbons with melting point 50oC, not less. As active component the composition comprises product of partial or complete neutralization of primary aliphatic C10-C20)-amines with (C2-C30)-carboxylic acids wherein part of neutralized amine is varied, and hydrocarbon solvent represents purified distillate or residual mineral oils, or a mixture of distillate and residual mineral oils containing the main fraction 85%, not less, with the boiling point above 350oC in the their following content in the composition, wt.-%: active component, 10-25; hydrocarbon solvent, 40-80; temperature modifying agent for fluidity loss, 1-20. The composition of temperature 70-100oC, viscosity value at this temperature 5-50 mPa*c, temperature fluidity loss 20-60oC is applied on surface of granules in the amount 0.02-0.2% of fertilizer mass to be treated. Components of the composition provides preparing inexpensive and effective conditioning composition that doesn't form aerosol in its applying on fertilizer and not aggressive to material of transporting bands used in transport of treated product. ^ EFFECT: improved preparing method, improved and valuable properties of composition. ^ 6 cl, 5 tbl, 4 ex |
