In this article, an anthropogenic influence on natural
ecosystem such as an excavation of sand is discussed.
Investigations were done in Kuyar Forest District of
the Mari El Republic on a sandpit. The adjacent plot
of natural forest was taken as a control. For evaluation
the degree of environment transformation as a result of
sand excavation several indicators were used. As
indicators of physical soil degradation - thickness of
organogenic horizon and soil density; for assessment a
chemical degradation – content of main nutrients and
humus; as an indicator of biological degradation – the
level of active microbial biomass. Besides, a potential
phytotoxicity was estimated. The study proved:
physical and chemical parameters corresponded with
the fourth degree of soil degradation, at the same time,
biological parameters approximated to parameters of
soil from natural territory
The article presents the results of studying the peculiarities of growth and fruiting of trees of sweet cherry with varying density. It is established that the average yield for the years of fruiting does not depend on tree planting schemes, and higher profitability of production is marked with the scheme of 5,0×3,0 5,0×2,5 m
The article gives an overview of the current
developments of scientists of the Russian Federation in
the field of production of feed concentrates and
premixes for cattle. A critical analysis of feed
concentrates and premixes of preventive and
compensatory action for the control of mycotoxicoses
was carried out, and their brief characteristics were
given. The characteristic of biologically active
substances and fillers, declared in the recipes of feed
concentrates and premixes, is given. It is shown that
the alternative to existing feed concentrates and
premixes on the market is vitamin-mineral fodder
concentrate "Tetra +", developed by the authors. Based
on the analysis, a conclusion was made about the
relevance of studies to identify the effectiveness of
vitamin-mineral fodder concentrate "Tetra +" in
livestock
In the article we have presented the results of cultivation of apple-tree gardens with the application of Buton and Mival-agro growth regulators and their efficiency on grades of all terms of maturing. Positive action of preparations on grades of all terms of maturing has been noted
The article presents the biological growth of above-ground parts in a nursery open ground. It gives the economic evaluation of the production of seed species and varieties of juniper, depending on the category of the source material
In the article we have studied the exterior of golshtinizaited animals. The increase in number of measurements for specific dairy type and increase of productivity has been established
In the article we present the results of the researches
on the study of the different systems of basic treatment
of soil on the plants of sunflower, as well as its
infestation by one-year and perennial weeds and its
productivity on usual black soils of the Krasnodar
region
The article presents the results of studies on the influence of predecessors and funds of intensification on the yield of spring wheat in the field crop rotations. Studies carried out in the long stationary experiment in crop rotations over the past seven rotations. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
The article deals with the problem of growing geese and explores the possibility of feeding young geese with rapeseeds of 00-type and their products
The problem of industrial poultry farming is the emergence of a growing birds’ arthritis. Inflamed joints are usually seen in poultry and accompanied by the inability to take food and water. The most characteristic of this problem in broiler chickens, young chickens of egg cross, i.e. birds of a short period of use. This is the reason for their rejection of the herd. Culling chickens are 10%, which furthermore reduces the total amount of livestock and leads to a reduction in the cost-effectiveness of growing birds. The analysis of our data gives a reason to believe that the main reason for culling poultry is acute inflammation of the joints or arthri-tis. According to the authors to ensure optimal rearing program, which should include the prevention of premature retirement of birds not only due to infectious diseases, but also the prevention of metabolic disorders and the exclusion of factors that could cause disruption of immunological reactivity. Currently, this program needs to be improved, which is particularly important in relation to vaccine pre-vention
