Abstract
A method for production a new fertilizer was proposed. This method is based on the impregnation of a substrate from pine bark with a water solution of ammonium nitrate, and containing 20.0 wt. % nitrogen. The physicochemical properties of a pine bark substrate and prepared fertilizers were studied. A field experiment was conducted on growing wheat of the variety “Krasnoyarskaya 12”. The yield of wheat when fertilized with pine bark was applied to the soil increased by 2.9 centners/ha compared to blank experiment without fertilizer. The use of this fertilizer results in an increase in the quality (higher nutritional value) of the grains in comparison blank experiments with ammonium nitrate and without fertilizer
