The paper is devoted to the study of the processes of heat and mass exchange, when drying ferrocene containing wastes of winemaking (FWW), and to the preparation of those wastes to be fed to dairy cattle. The goals of the article are: to determine the amount of energy costs for drying FWW that are necessary for calculating the net cost of feed additives, and to estimate the economic efficiency of the suggested technological and technical solutions; and also to justify and develop the methods for estimating quantitative parameters when removing liquid from the wastes of wine production. Moisture and heat exchange are studied in the “heat agent - drying object” system for convective and infrared drying. A combined method is proposed for drying winemaking waste, to substantiate the sequence of stages and parameters of the process, a graph-analytic model, that is dwelled on the basic principles of convective and infrared drying, is designed. Numerical calculations helped to obtain graphical dependences of the energy costs of the drying process on the air velocity in the drying chamber at different temperatures of the air (for convective and infrared). The model of drying in the form of comparative graphical dependences of the reduced value of the drying speed to the heat flux on the moisture content of the mass subjected to drying is presented. Given the above data, it is recommended to use combined two-phase drying: in the first phase, use infrared radiation, when in the second phase - convective way, in order to reduce the humidity of ferrocene containing winemaking wastes from initial moisture content of 80% to the required value of 18-20% with the further use as neutralizing additives in the feed of dairy cattle. It is also suggested to use the renewable energy sources for heating in order to cut the expenses in the phase of convective drying.

One of the promising directions in the fight against the emergence and spread of farm animal microbiota resistance factors is the development and search for feed additives that can inhibit the SOSresponse. SOS-response is one of the main mechanisms of the occurrence of mutations in bacteria. Plants used in traditional medicine can be a promising source of safe substances that reduce the SOS-response of bacteria. A screening of plants potentially containing substances with antiSOS activity was performed. During the initial screening, the E. coli MG 1655 pRecA-lux biosensor strain with ciprofloxacin as RecA inducer was used. Seven plants were identified whose extracts reduced the expression of the RecA operon. In further experiments on bacteria exposed to antibiotics, we identified four plants whose exstracts significantly reduced the mutagenesis rate of clinical E. coli strains: Austrian broom (Cytisus austriacus), greater celandine (Chelidonium majus), walnut (Juglans regia) and smooth sumac (Rhus glabra).

Territory marketing is a popular area in terms of developing directions for territorial development and practical steps for the implementation of this activity. The interest in this area has been updated due to the development of globalization and increased competition of territories with each other. However, in the scientific literature there are many similar concepts related to territorial marketing, territorial marketing and regional marketing, which requires understanding and understanding of their essential characteristics and relationships. Along with this, it is of objective interest to characterize the main approaches to territory marketing due to their high demand for Russian reality.

The development of new technologies and a complex of machines for applying mineral and liquid fertilizers is going on more and more intensively. Due to the warming climate, more frequent years with arid conditions during the ripening period of plants, the requirements for the complex of machines for applying fertilizers are changing. „Amazonen-Werke“ or „AMAZONE“ is a pioneer in precision farming, differentiated fertilization with the use of automation, electronics and telematics systems in agriculture. The article presents materials of new technical solutions for the introduction of both granular and liquid fertilizers. Especially the development and research of new machines in the arid regions of Russia, allow you to find the optimal solution in the application of liquid fertilizers.

The article presents an overview of perennial grain crops, gives a comparative characteristic of annual winter wheat and perennial grain crops such as Trititrigia (Trititrigia cziczinii Tsvelev), Thinopyrum intermedium, perennial rye (Secale cereale L) and perennial sorghum (Sorghum x derzhavinii Tzvel.). The study aims to consider the main perennial crops grown in Russia and in the world, to compare their quality indicators, sowing agrotechnical requirements, cultivation conditions, yields, and to justify the choice of perennial crops that meet the needs and climatic conditions of the Rostov region. Presented is the generalized information on the grain quality changes during maturation, ripeness phases of grain crops are considered. Based on the review, the optimal ripeness phases, at which it is advisable to harvest are presented. Literature review showed that in the phase of lactic (мoлoчнaя cпeлocть) and wax maturity (вocкoвaя cпeлocть) wheat grain contains the greatest amount of basic nutrients. It was found that perennial crops have a positive effect on the state of the soil: prevent its erosion and depletion; there is an accumulation of carbon, soil methane CH 4. Comparative characterization of perennial crops with annual crops shows increased protein content - on average 2-3% higher. Also considered are the green mass quality indicators of perennial crops as a source of nutrients in the feed-production technology.
