The article discusses the prospects for the development of environmental management in the disposal of livestock waste, in particular liquid manure, as part of an industrial approach to it. The data on the concentration of nutrients in liquid manure depending on its moisture are presented. Based on the analysis of empirical data and the results of previous studies, an exponential dependence is derived that indicates the relationship between the initial moisture content of liquid manure and its final volume. Criteria of effective utilization of liquid manure are formulated taking into account environmental and technological specifics.

Introduction. A perspective method of the livestock wastes disinfection is considered. The key point of the method is in complex physical and chemical impact of the variable magnetic field coupled with a chemical reagent. The device for implementing the proposed technique is an inductor. Electric energy intensity is selected as a parameter characterizing the energy efficiency of the of livestock wastes disinfection process. To increase the efficiency of investigating the livestock wastes disinfection process, it is proposed to use the mathematical experimental design theory. Materials and Methods. In the course of this research, the following techniques were used: instrument, direct and indirect methods of measurement, statistical processing technique, and mathematical experimental design theory. Research Results. The effect of technological factors on the energy efficiency of the livestock wastes disinfection process is experimentally investigated. On the basis of the data obtained, the strength effect ranking of the technology factors on the specific electrical energy capacity of the process is performed. A noncritical degree of impact of evaluating the pair-wise interaction coefficients is established. Their absence in the mathematical model suggests this. Discussion and Conclusions. A mathematical model of the livestock wastes disinfection process which allows evaluating the effect of the technology factors on the specific electrical energy intensity...
A method for intensifying environmentally friendly biotransformation of a liquid fraction of pork liquid manure into a bioorganic fertilizer based on a structural information model, which is the initial data for the development of digital solutions, is described. The theory of potential efficiency is used as the basic tool of the structural and information model. An information model of a digitalized control system is proposed as a basis for the development of software systems and intelligent control solutions.
The inductor which allows the usage of the magnetic field in the agriculture technological processes is considered. The measuring technique of the electromagnetic field vector characterization - magnetic induction that evaluates the quality of the technological process in the inductor chamber - is offered. Intensity, directivity, and uniformity of the magnetic field in the inductor working chamber are investigated. The techniques of the instrumental, direct and indirect measurements, and statistical data processing, as well as methods of analog-to-digital data conversion are used. A cybernetic model of the experimental research to assess the inductor performance quality is developed. The distribution of the radial and axial components of the magnetic induction in the working chamber is determined; the area with the most uniform magnitude and the magnetic-field direction which forms the inductor working area is identified. The most significant component of the magnetic induction vector for this process and the type of inductor is revealed. The results obtained are important for the development of new inductor constructions.
