Abstract
The possibility of preparation of phosphorus fertilizers with prolonged time of action by impregnation of porous supports from birch bark and inner birch bark by water solution of К2НРО4 was shown. Influence of the preparation conditions of the fertilizers on the phosphates leaching by water was studied. The conditions which allow to obtain the fertilizers with minimal phosphates leaching at a long time were determined.
