The main purpose of this study was to explore the effects of the recommended usage level and twice the recommended usage level of the long-acting herbicide fomesafen on the soil enzymes and microbial community structure in chernozems of soybean fields. Culturable microbial biomass and phospholipid fatty acids (PLFA) were used as the main references for this evaluation. The digestion curve of fomesafen in soil conforms to the law of a single exponential function. The activities of four soil enzymes decreased significantly when exposed to twice the recommended amount, and then returned to the control level. The inhibition of the fungal and bacterial biomass section of culturable microorganisms in soil at twice the recommended usage level was greater than that under the recommended usage level, and this dosage also stimulated the rapid recovery of the initial level of fungal biomass before the application of fomesafen. The PLFA analysis showed that the ratio of GN/GP decreased significantly, and soil pressure increased significantly. Compared with the recommended usage level, the effect of twice the recommended usage level of fomesafen on soil microbial community structures was more significant. This provides a reference for environmental location recommendations, environmental safety assessments, and the rational use of herbicides.

Purpose. The article is aimed at analyzing the general theoretical principles and the essential characteristics of legal restrictions in environmental law; defining category of “environmental legal restrictions”, their content, system and the status of the respective legislation. Methodology. The methodology consists in carrying out a comprehensive analysis of the provisions of environmental legislation and formulating relevant conclusions on this basis. During the research, the following methods of scientific research were used: terminological, systemic and structural, comparative legal, structural and functional. Results. The objectively determined necessity of unconditional adherence to the legally established environmental requirements, prohibitions and restrictions as well as their potential scientifically substantiated enhancement in order to achieve environmentally significant goals oriented towards the priorities of sustainable development is substantiated. Restrictive mechanisms are scattered across statutory and regulatory acts of different legal force and even different branches of law, therefore, the need for their systematization and unification as well as generalization of the experience of their practical implementation in order to establish a comprehensive system of environmental restrictions is discussed. In our opinion, the conceptual basis and general essential characteristics of public environmental requirements and restrictions should be reflected in the future Environmental Code of Ukraine. Scientific novelty. In the course of the research, the author defines restrictions in environmental law as a specific sectoral imperative mechanism for regulating relations in the field of environmental safety, which consists in systematically introducing legislation on imperative provisions of environmental law as well as establishing specific legal regimes and mechanisms for their application and implementation. Practical significance. The main conclusions can be used in law-making and law-enforcing activities, as well as in further theoretical and legal research and in the educational process.
