Studies in which new phosphorus fertilizers containing additional organic substances are a tool for regulating soil fertility are described in this paper. The fertilizers were developed in Institute of General and Inorganic of Uzbek Academy Sciences. Phosphate fertilizers were obtained by decomposition of ordinary phosphorite powder with acid effluent that is a waste from the soap production of Urganch yog'-moy JSC in various ratios. According to the developers, ordinary phosphate powder (OPP), due to the treatment with acid effluent (AE), acquires new qualities as slowly soluble properties, which allows for a more rational use of nutrients, in particular phosphorus, increasing its efficiency and reducing wasteful losses. In addition, the introduction of organic substances into the composition of the AE enriches the phosphorus fertilizer with biologically active compounds, and gives it valuable growth-stimulating properties. New fertilizers are intended for use in irrigated agriculture, which have long lasting properties. It is assumed that derived fertilizers contribute to the improvement of the physical and chemical properties of the soil, optimize the vital activity of the cultivated crop without a negative increase in the activity of soil microorganisms. |
