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
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
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
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
We have studied changes in flora, humus content, peroxidase activity and polyphenoloxidase in ordinary black soils in natural succession of different-age deposits. We have also selected stage successions in uneven deposits
The article presents the results of the researches of growth and fructification of grades and forms of the Chinese date (unaba) in the Prikubansky zone of fruit growing. The biological features of the varieties and forms of unaba which are selected during researches
on a research field of Kuban state agrarian university in the Prikubansky zone of fruit growing are considered. Novelty of work – such researches were conducted in Kuban for the first time
We have described the theoretical assumptions and methodological solutions in the present review. They are innovative possibilities in the development of laboratory methods for assessing biological features of grain during the selection process
The results of biological recultivation of disturbed lands are offered in the article. Silvicultural and taxation parameters of basic wood types of dumps and their role in stable ecosystem formation are presented
Results of the use of plant protein feed additives containing pumpkin paste and soybean seeds of different varieties for quail are presented in the article. It was established that the use of such
additives on the basis of Valens soybean allowed to receive higher growth parameters than groups treated with Vilan soybean additive
The article provides the data of studying the biological
properties of Newcastle disease virus isolates
NDV/Pigeon/Rus/Kursk/1/13 and NDV/Pigeon/Rus/Kursk/2/13 derived from pigeons in pigeon houses in the Kursk region in 2013 using virological and molecular genetic methods
