Urea phosphate as a component of complex NPCa-fertilizers


  • Yu. I. Vetsner National Technical University "Kharkiv Polytechnic Institute"


The use of mineral fertilizers is one of the main criteria for increasing yields in agriculture. Complex fertilizers, which contain both nitrogen and phosphorus, are of particular importance. To provide agriculture with complex fertilizers, technologies based on the use of phosphorus-containing raw materials, which are located in Ukraine, are promising. Of particular practical interest is the use of carbamide due to its ability to form complex fertilizers with almost all inorganic acids and salts. This contributes to the production of complex fertilizers with various forms of nutrients, which slowly decompose under the action of soil solutions or water, which leads to the transition of phosphates fixed in the soil to assimilable ones.
