Аннотация: The possibility of preparation of biocomposite fertilizer with a long-time action by impregnation of porous support from larch bark by water solution of K2HPO4 was shown. The conditions of alkali treatment of a larch bark which can provide porous supports with a low content of the soluble substances toxiferous for plants. The growtПоказать полностьюh stimulate action of porous supports from a larch bark depending on the soluble substances contain into them was revealed at vegetation tests. Effect of salt natural, temperature of an impregnated support drying and conditions of her acid treatment on the phosphates and potassium leaching by water from biocomposite fertilizers was studied. Choice of the preparation conditions providing the greatest resistant of phosphorus-potassium fertilizer for active components leaching by water was held. It was determined, that the fertilizer based on larch bark is able to slow release of active components in long time. In experiments were find that 43,6 % phosphates and 53,3 % potassium are leaching by water due 10 days from the fertilizer obtained at optimum conditions, that provides their effect of a long-time action. It was shown, that the developed biocomposite phosphorus-potassium fertilizer surpass in resistant to phosphates and potassium leaching a commercial granulated fertilizer.
