Abstract
The environmental impact of residual mineral
fertilizers not utilized by plants is analyzed. 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.
