In the article, we have studied the effect of lead contamination, an alternating magnetic field, their combination on such groups of soil microorganisms, as ammonifying, amylolytic, nitrogen-fixing bacteria, and micromycetes. The pollution had a significant and different effect on the number of soil microorganisms. The nature and extent of this effect varied depending on the level of impact of each factor, and they were not linear
We studied the resistance of the eight strains of oil-destructive actinomycetes, isolated from the oil-contaminated ecosystems to heavy metal salts when cultivatiwng with different carbon sources. Furthermore we researched feasibility to use those microorganisms for bioremediation of oil- contaminated sites with high level of heavy metals
The cost-effectiveness of animal husbandry in the conditions of Yakutia causes irreparable damage to viral diseases, such as salmonellosis, viral hepatitis, parvovirus enteritis and others. Based on this, in animal husbandry, increased attention is paid to the prevention of viral diseases. The work was carried out in the period from 2009 to 2012. in the conditions of LLC "Pokrovskoye animal husbandry" of the Khangalassky ulus of the Sakha Republic (Yakutia). Boning of young animals showed that all his indicators were higher for pups born in 2011. So body size and physique are rated higher by 15.15%, in males - by 20.58%. Hair color was better in females by 19.44%, in males by 22.66%. As a result, the classiness of the animals of the experimental groups was higher than that of pups born in 2010. The commodity properties of the animal products of experimental animals and its cost are consistent with the results of the valuation. The offset on the quality of the fur products of the experimental groups in 2011 was determined at 89.02%, which is higher than the 2010 results by 10.32%. The average cost of one fur of a silver-black fox in 2011 was 2225.62 rubles. Additional vaccination of the main herd of foxes in autumn against the viral diseases with the vaccine "Multikan-6" has a positive effect on the quality of the fur products. The economic effect amounted to 258.62 rubles per 1 skin of a silver-black fox (at 2020 prices)
Five-year data of the influence of direct affect and the post action of decomposed turkey droppings on the sunflower husk on crop productivity in three-level field crop rotation of spring barley - sunflower -spring barley and in a comparison of its action with the effect of fertilizers on crop yields were presented in the article. The affect of the droppings exceeded affect of mineral fertilizers on the productivity of field crop ro-tation link in a dose of N90P90K90 on 0,79 t/ ga or on 16%
Foundation of the advantages of small agricultural firms of large- and middle-size agricultural firms is considered in this paper. The functions and factors
of creation and development of small agricultural
firms are discussed.
The article demonstrates the results of therapeutic and preventive effectiveness of the use of lactic acid bacteria – Lactobacillus brevis and Lactobacillus parabuchneri in laboratory animals, in particular mice and rats. They were isolated from the gastrointestinal tract of a wild quail in experimental violation of the intestinal microbial background. Artificial imbalance of the intestinal microbiota of experimental animals was caused by the use of the antibiotic. As a result of tests it was established that the application of probiotic cultures improved microbial disorders of the gut, however, the use of their consortium in the probiotic promoted consistent clinical result characterized by an elevated level of representatives of the normal flora (lacto- and bifidobacteria) and reduction of the number of representatives of pathogenic and conditionally pathogenic microbiota, with subsequent achievement of a level characteristic of healthy animals

There was substantiated the economic reasonability of intraeconomic combined food production effectiveness with the use of extruding method allowing to decrease specific costs and to increase the production profitability of livestock produce
In the article we present the system of estimation of the efficiency of innovation activities; we have also conducted a comprehensive analysis of the current state of agriculture and market of fruits of Kabardino–Balkaria, we have studied modern technological level and proved the main directions of the introduction of modern innovative technologies in horticulture; we have made the analysis of existing system of state support innovation activities in the fruit–growing and identified the priority forms of its improvement of the sustainable development in multistructure production of horticultural products
It is important to use tank mixtures of chemical weed killers with the biological preparations straight after the compounding. The Difesan doesn’t affect negatively on the viability of the Azothobacter chroococcum and Bacillus musilagenosus bacteria. Biological preparations in mixture with weed killers improve the yield productivity a lot
