Summary:The method of preparation of phosphorus organo-mineral fertilizers with the increase resistanceto leaching of mineral components by waterbased on the impregnation of aspen bark by water solution of КН2РО4 and its transformation into low soluble compound Са(Н2РО4)2 was developed. The optimal condition of fertilizers preparation, ensuring minimum leaching of phosphates and potassium were selected. The possibility of enrichment of fertilizers by microelements (Mg, Cu, Zn, Fe) without the loss of their water resistance was shown. The increased resistanceof designed fertilizers on the basis of aspen bark to leaching of mineral components by water determines their prolonged action. As a result of vegetation growth experiments the stimulating effect ofphosphateorgano-mineral fertilizers on the basis of aspen barkwas shown.
