The article describes the methods of phosphate-thermal decomposition of phosphate rock S.K. The conversion of phosphorus as a result of heat treatment under conditions of reduced conditions of a reduced rate of phosphoric acid is given.Condensed phosphates are highly concentrated fertilizers and have advantages over conventional low percent fertilizers in terms of savings in transport, storage and use. They are less susceptible to degradation in the soil, are distinguished by a long aftereffect and a higher coefficient of phosphorus utilization by plants.
