Development of a flexible technological scheme for producing complex fertilizers

The safety of fertilizers in storage, transportation in various types of transport and the effectiveness of their use in agriculture depend on their physicochemical and commercial properties. On this basis, we studied the physicochemical and commercial properties of new types of phosphorus and nitrogen-phosphorus fertilizers obtained in the process of processing samples of Karakalpakstan phosphate by mineral salt solutions, with an incomplete rate of sulfuric and nitric acid with the introduction of ammonium sulfate and nitrate. A technological scheme was developed for obtaining new types of phosphate fertilizers by decomposing the bare Karakalpak phosphate with an incomplete rate of sulfuric and nitric acids, as well as in the presence of their ammonium salts.
