A retrospective analysis of the literature data on the production of phosphorus-containing fertilizers by decomposition of apatite concentrate using mineral acids and industrial waste-spent sulfuric acid of petrochemical synthesis, including molybdenum acid solution of electric lamp production. It was determined that the decomposition of apatite concentrate with spent sulfuric acid of petrochemical and organic synthesis increases the shelf life of phosphorus fertilizer, since the acid contains organic substances that inhibit the process. It has been established that the decomposition process of apatite concentrate with a mixture of spent sulfuric acid and molybdenum acid solution, at a certain ratio, reduces the shelf life of phosphorus fertilizer, while simultaneously enriching it with a trace element-molybdenum. Appropriate laboratory experiments were carried out, the physico-chemical and analytical characteristics of the obtained phosphorus fertilizer enriched with the trace element molybdenum were studied. The results obtained have been confirmed by X-ray, electron microscopic studies. It has been established that it is possible to obtain a phosphorus fertilizer enriched with a trace element-molybdenum by the proposed method. This method meets the existing regulatory and technical standards
