It is shown that this negative effect extends to all elements of the environment: soil, atmosphere, hydrosphere. The perspective of the application of encapsulated mineral fertilizers that allow prolonged release of plant nutrients is outlined. The appliccation of modified polyethylene terephthalate (PETF) as a capsule-forming material for encapsulated mineral fertilizers is proposed. PET modification and fertilizer encapsulation technologies have been tested. The dynamics of the release of nutrients from fertilizers encapsulated by PET has been studied. The kinetics of watercress salad growth with the use of granular and encapsulated fertilizers has been investigated.95-101engranulated mineral fertilizersencapsulated mineral fertilizersenvironmentnutrientspolyethylene terephthalatereleaseArticle© Національний університет “Львівська політехніка”, 2029© Synelnikov S., Malovanyy M., Nahurskyy O., Luchyt L., Petrushka K., Tymchuk I., Stokaliuk O., 20207doi.org/10.23939/ep2020.02.095Theoretical and practical aspects of the efficiency of application of mineral fertilizers encapsulated with polyethylene terephthalate / Serhiy Synelnikov, Myroslav Malovanyy, Oleh Nahurskyy, Liubov Luchyt, Kateryna Petrushka, Ivan Tymchuk, Oleh Stokaliuko // Environmental Problems. — Lviv : Lviv Politechnic Publishing House, 2020. — Vol 5. — No 2. — P. 95–101.
