ABSTRACT
Traditional use of products of chemical synthesis derived from nonrenewable natural resources leads to excessive and increasing accumulation of non-recyclable wastes, coming into conflict with environmental protection activities and posing a global environmental problem. Research performed to implement the project has produced new data on degradable polyhydroxyalkanoates (PHA) as material for constructing slow-release formulations of agrochemicals. Positive evaluation of the effectiveness of using the slow-release chemical formulations in laboratory conditions: in soil ecosystems with known properties containing higher plants infected by plant pathogens and weeds. The chapter examines chemical composition of the soils and the structure of soil microbial communities and revealed the dominant microbial species, including primary degraders of PHAs of different chemical compositions. The composition of the matrix had a substantial effect on the release of the agrochemicals. By varying the composition of the matrix and by coating nitrogen fertilizer with a polymer, one can regulate release rates of the active ingredient within a wide range.
