The article deals with the development of new eco-innovative technologies, evaluation of their effectiveness and raising the widest possible awareness of those categories to the people who could effectively use the proposed technologies. It was found that the personal position of economic entities is the core of the structural organization of psychological readiness for ecologically oriented innovation and is manifested in the forms of free ecologically oriented will. The paper discusses the main methods of removal of nutrients from wastewater, as well as presents promising technologies and techniques. It contains the recommendations for optimal conditions for the precipitation of ammonia nitrogen from an ion exchange regenerator for further use as an ammonium fertilizer. The maximum efficiency of ammonium nitrogen removal was established. According to the results of the best options, the deposition of real ion exchange concentrates was carried out. The humidity level was set during the drying of mineral fertilizers. The moisture content determined the content of sediment, which is close to the number of water molecules to the formula of the fertilizer MgNH4PO4 · 5H2O. Complex phosphate fertilizer struvite was characterized. A comparative agronomic evaluation of synthetic struvite was performed. The influence of struvite on the processes of germination of cultivated plants was carried out. The results show that the method of obtaining struvite does not significantly affect the processes of wheat germination, and the determining factor in the effectiveness of fertilizers is the method of its application and dosage.
