Published: April 2021

Abstract
The article addresses the problem of processing organic waste from the agro-industrial complex. To solve the problem of processing biomass, it is proposed to use gas-generating units that convert the resulting biomass into biogas. Particular attention is paid to the principles of operation of gas generators, the description of the stages of gasification, and the ongoing chemical processes. The scientific novelty lies in the proposal for the introduction of intelligent technology based on artificial neural networks to predict product quality and control the gasification process at each stage. As a result of the study, it was revealed that the use of information technology contributes to the optimization of the production process.

Abstract
Variants of developing a mathematical model for predicting pasture fertility based on the use of remote sensing data from the Earth and ground based measurements on test field plots are presented. The NDVI data, which is a time series with pronounced seasonal features in the form of one or two maxima, are the basis for obtaining the vegetation index forecast model (NDVI) from the currently available measurements. To predict the parameters of this maximum, we used the position on the time axis, width, amplitude, and its shape. Using various model regressions over the entire available time interval, it is possible to obtain models, for example, in the form of rational and polynomial functions. As model, in addition to the rational and polynomial ones presented above, we used the following functions with characteristic impulse behavior: Cauchy, arctg (x)’, Verhulst, Gompertz differential functions (derivatives) with left and right asymmetries, as well as the sum fs and the product fp of logistic functions Verhulst. Of all the options on the evaluation interval [56 and 180] days, the model in the form of the sum of the Verhulst logistic functions with 7 evaluated parameters turned out to be more effective. The results show that all parameters are statistically significant, and the corrected determination coefficient is large enough: 0.9545. However, to parameterize the model, observations are needed “on the decline” of the time series - 150-180 days from the beginning of the year. The use of mathematical models is necessary for managing pasture plots and the need for timely management decisions of various kinds - alternating corrals, mowing terms for grass stands, and fertilizing. To generate reliable information about the state of pastures, the use of remote monitoring is relevant.

Published: April 2021

Abstract
As you know, modern farms equipp many technological devices, the operation of which directly affects the volume of agricultural products, the period of readiness, their quality, shelf life, etc., in this regard, the issues of assessing the response time and reaction to information flows are relevant. The article presents the results of constructing a model based on real-time systems for assessing system stability and the response time of a subject (farmer) to information messages from IoT devices to the subject’s smartphone, depending on the time of performing current, priority and critical technological operations, their relevance, as well as on the level of information noise and the availability of resources. The analysis of the model revealed that an increase in the number of control objects and information messages increases the system response delay time from 0 to 36.5 hours which will especially depends on the receipt of priority and critical messages. The article offers solutions to reduce the response time, in particular by dividing the message flow into production and personal, resource optimization, using digital technologies (IoT), databases and improving the information skills of farmers.

Abstract
Currently, in Russia, the North American technology of keeping pigs with a combined rearing and fattening area (CFSWP) is becoming widespread. It is essentially a two-phase technology for keeping pigs. Many years of research conducted by the authors of the article have shown that the most effective technology is a stress-free methods of keeping pigs. However, it usage is limited by the capacity of the pig farm and the size of the pigsties. A new technology with elements of stress-free pig housing has been developed for a pig farm for the reproduction, rearing and fattening of 12000 pigs per year with a combined sow farrowing and weaning piglet rearing area (CFSWP) in order to form piglets nests at the stages of the suckling period and rearing. Thus, the usage of the new technology is appropriate for pork production industrial enterprises. The usage of this solution allows you to limit the impact of stress on piglets at the most vulnerable stages of cultivation – the suckling period and rearing. The new technology is compared with a standard project that is widely used in Russia according to the developed author’s methodology. The evaluation criteria are the following indicators: the usage of the area of the main purpose and the payment of the area by the production of meat. Despite the fact that the marketable weight of pigs on a farm with the new technology is only 3.8% higher, the payment criterion for the main purpose area is 1.39-1.4 times more effective in comparison with the basic technology. The use of the new three-phase technology with CFSWP will reduce the total area of suckling sows, weaned pigs and fattening pigs by 9.5 %, and increase the productivity of weaned pigs and fattening pigs to 10%.

Published: April 2021

Abstract
Artificial irradiation in protected ground structures is use for growing seedlings and for breeding purposes. Despite the increase in the cost of seedlings, additional lighting is effective, since it increases the yield by 20 … 30% and accelerates its production by 10 … 15 days [1]. Electrostimulation of plants of this development is carried out by intensifying plant growth by creating an optimal spectrum and regulating lighting depending on the actual natural illumination, automatic spectrum control for various plants, and irrigation system. The effectiveness of the development is to improve the useful properties of plants, reduce the cost of caring for them, which allows you to engage in a family business. The disadvantage of this installation is the need for high labor costs due to growing plants without taking into account the objective need for timely watering with foliar spray with a nutrient solution or timely feeding of the nutrient solution directly into the ground, depending on the soil moisture. In addition, the method does not provide for the cultivation of tomato seedlings in the presence of objective control of insufficient illumination in winter, requiring additional illumination for the required period of time with a certain duration for the effectiveness of the process.

Published: April 2021

Abstract
The article discusses the methodology for determining the cadastral value of the permitted use first type agricultural land, used in the assessment in 2012 in the Samara region conditions. It was based on the income valuation method. The considered method made it possible to more accurately determine the cadastral value in comparison with the methods used earlier. The purpose of the study is to improve the methodology for the agricultural land cadastral valuation, taking into account the potential yield, soil varieties, plots individual technological properties and other factors. The average cost of one square meter of the use first type agricultural land, calculated according to the proposed methodology, is more than the average indicator determined in 2006 by 1.35 times (by 35%). The study results indicate that the method for determining the cadastral value of the use first type agricultural land works quite correctly. It effectively fulfills the most important task: a land plot with the worst fertility and having a minimum indicator of agroclimatic potential costs less than a land plot with a fertility higher level and the value of an agroclimatic potential indicator. In addition, the proposed methodology is based on data from the Federal State Statistics Service, which ensures their reliability. These factors determine the merits of the proposed methodology for the state agricultural land cadastral valuation.

Published: April 2021

Abstract
The article presents the results of a study of natural-anthropogenic complexes of rural areas, which are formed in the process of production of grain crops, as active systems. The features of the management of active systems in the subject-subject paradigm of relationships are shown, the necessity of using network management based on communication links and reflexive processes as a basic type of management of natural-anthropogenic complexes of rural areas is substantiated. The natural-anthropogenic complex as a subject of management is presented in the form of four active subsystems interacting with each other and with the environment external to the complex. This interaction is based on the formation and development of networks in the field of technological support for the functioning of the natural-anthropogenic complex, formal and informal social networks formed by the population of rural areas, networks that include elements of the economic subsystem and ecological networks of rural areas, formed as under the influence of economic activity a person, and regardless of its presence in a particular territory. In the conclusion, data are presented that indicate the need for further development of ideas about the management of natural-anthropogenic complexes of rural areas at the methodological level within the framework of the post-non-classical type of scientific rationality and environmental management of complex self-developing systems, into which natural-anthropogenic complexes of rural areas are gradually transformed.

Published: April 2021

Abstract
The structural parameters of plankton, benthos and macrophytes after large-scale technogenic transformation of the mouth area of the river were studied. Pregolya. A decrease in the species richness and area of growth of macrophytes, a simplification of the structure of communities was noted. The renewal of plant communities in the places of their origin was recorded, primarily due to the species resistant to biogenic pollution. A decrease in the abundance of submerged species with wide leaves was revealed, which is an indicator of an increase in water turbidity. The species were found in the phyto- and zooplankton community, living in conditions of an increased content of nutrients and suspended matter. There was no significant decrease in the species diversity of summer plankton and benthos, and the quantitative indicators are comparable with the data before the work. A feature of the restoration of the zooplankton and benthic community was the appearance of brackish-water species in the river branches, which were not previously recorded there, incl. alien species of mollusks and polychaetes.
