BIOHUMATE EFFECTS ON SOIL BIOTA

abstract 1141510074 issue 114 pp. 978 – 987 30.12.2015 ru 1006
The article represents the results of the experiment on biohumate «Vermistar» (which was obtained by vermiculturing) and its effects on mycological soil composition. Humic preparations are interesting in the way of detoxication of soil. When humic compounds are active, herbicides and pesticide decompose faster and concentrations of heavy metals are lowered. Adding humic fertilizers affect the physical properties of water-Soil: increases capillary and light soil field capacity (an average of 20-30%) and heavy water permeability, improves the structure and its water stability, reduced soil density. It was noted, that low doses of humic fertilizer contributes to water-stable aggregates, and high - change the ratio of the structural units in favor of agronomically valuable fractions. This, in turn, is accompanied by changes in the humus state, and biological characteristics of the soil. Moreover, increased microbial activity was observed in the first year of application of fertilizers and as an aftereffect. The maximum total number of microorganisms established in the initial phases of plant development. The increase in the number of microorganisms is enhanced and the enzymatic activity of the soil which in turn increases the mobility of soil nutrients

BIOLOGICAL ACTIVITY OF URBAN SOILS (ON THE EXAMPLE OF ROSTOV-ON-DON)

abstract 0851301022 issue 85 pp. 291 – 305 28.01.2013 ru 1614
About 40 soil cuts were made in various parts of the city of Rostov-on-Don. The determinations of enzyme activity (catalase, invertase, polyphenoloxidase) were carried out in natural and antropogenic soils of a sub-urban park, residential and industrial areas of the city. The enzyme activity of soils in urban condition signif-icantly lowers than in non-urban soils. It is established, that significant impact on the biological activity has duration of sealing, and the longer the period, the higher the negative impact on the enzymes activity. However, a close relationship between humus state of soil and its enzyme activity kept in a condition of ur-ban pedogenesis. The high activity of investigated enzymes is typical to soil horizons which contain the highest amount of soil organic matter

BIOLOGICAL AND PRODUCTIVE RESOURCES OF LACTATING COWS AT DENITRIFICATION

abstract 1111507104 issue 111 pp. 1593 – 1605 30.09.2015 ru 861
The article presents the results obtained in the process of two scientific-practical experiments carried jut on two milk cows (Shvitskay breed) aimed at the antioxidants detoxication properties and mould inhibitor revealing. This factor is actual in the Republic of North Ossetia-Alania as the intensive technologies of the fodder crops cultivation using the nitrate fertilizers are widely applied in the region leading to the excess nitrates and nitrite penetration into the animals’ organism. During the first experiment, the antioxidants of epophen and vitamin C were added into the ration of the lactating cows with the subtoxic dosage of nitrates both separately and in complex. The complex feeding proved to increase the milk productivity, the fat mass and protein mass in milk while reducing the fodder expenditure per product unit. Beside, the lactating cows revealed the digestive and intermediate exchange betterment and the reduction of nitrates and nitrites level in blood. The second experiment helped to study Khadoks antioxidant and mould inhibitor called Mold-Zap efficiency use for the nitrates and aflotoxicin B1 detoxication. The researches showed that the complex admixtures of the said preparations introduction into the rations of the animals increased the milk productivity, fat and protein content and reduced aflatoxineM1 content. The cows activated the digestive and intermediate exchange, accompanied with the nitrates and nitrites level reduction in the organism

BIOLOGICAL CHARACTERISTICS AND COMMERCIAL STOCKS OF HUMPBACK WHITEFISH IN YAKUTIA WATERS

abstract 1181604100 issue 118 pp. 1530 – 1542 29.04.2016 ru 872
Humpback whitefish - Coregonus lavaretus pidschian (Gmelin, 1788), is spread in Siberia, in the Kara, Laptev and East Siberian seas and in the lakes of the Arctic and Subarctic. Objective: To assess the status of fish in the waters of Yakutia, to make ecological forecasts and determine the possibility and prospect of economic use of whitefish, as a fish-breeding material in the present conditions. Methods: The analysis was carried out on the fresh material as described I.Pravdina (1966), taking into account the recommendations of Y. Reshetnikov (1980). Collection and processing of materials were carried out in 1969-2015 by standard methods. Results. Reaching sexual maturity at the sixth (in weight - the eighth and ninth) year of life, whitefish begin to move to the main breeding groundsin the early fall. Absolute fecundity of eggs 2500-140000. Spawning is common in late September-early October. The food spectrum usually consists of the following objects: chironomid larvae, plants, mollusks, fish eggs and copepods. By the nature of power - benthophage, but often becomes planktonic organisms. Conclusions. Important food fish, but its reserves significantly reducedunder the influence of anthropogenic factors in recent years. The catch of whitefish can be increased as a result of the development of aquaculture
