Synthesis and study of properties of slow-discharge urea based on polivinyl acetate and bentonite. By analyzing IR, XRD, SEM, it is shown that the presence of polivinyl acetate and bentonite stabilizes the fertilizer structure, slows down the nitrogen release process of urea, reduces fertilizer losses and minimizes environmental pollution. The results showed that with the fertilizer sample, the proportion of urea bentonite PVAc in the mixture was 90: 10: 4, releasing about 60.15% of nitrogen in 12 hours in water and 71.12% of nitrogen in 28 days. in soil environment.
