In the article there were analyzed the different approaches of Soviet and Russian authors to the assessment of soils regarding to agro-ecological factors. There was given the characteristic of natural-economic zones territorially entering the Azov-Kuban lowland by main soil-climatic indexes. There was considered the valuation of soils which determines their relative value and suitability on main factors of natural fertility or their groups, it serves as a criteria of unification of soils into agro-ecological groups. There were shown the main indexes and order of grouping of soils under unification of different soils into agro-ecological groups. There was calculated the “normative” productivity of main agricultural crops on natural-economic zones of Azov-Kuban lowland which defines the agro-productive value of soil. There were revealed the disadvantages of soil assessment method used in the course of state cadastre valuation of agricultural lands asserted by the order of the Ministry of Economic Development from 20.09.2010 № 445. There were cited the specific rates of cadastre cost (SRCC) of agricultural lands on municipal entities of Krasnodar region. There was given the assessment of obtained data regarding to natural-climatic factors of the region, there were made proposals on optimization of trends of further researches on claimed problem
Urban trees can provide multiple environmental
benefits. The study of the state of the street tree and
shrubby vegetation from the analysis of inventory data
and environmental conditions is purpose the article.
The structure of 11 types of street roadside vegetation,
which determines about 93% of the greenery
composition of the city of Ekaterinburg is considered.
The structure of the examined tree-shrub vegetation
and all vegetation, which is part of the greening of
Ekaterinburg, is compared. For each tree (shrub) was
measured: species, number of stems, diameter of stem
at 1,3 m, tree height, height to base of live crown,
crown width, percent of branch dieback in crown,
percent of canopy volume devoid of leaves, number of
sides of the tree receiving sunlight from above,
distance and direction to building, distance to road. As
a result, homogeneity of illumination of various plant
species is received. Ash ordinary has the largest of all
plants values of the percent of the missing crown
(61.3%) and closest distance to the road. The effect on
the plants (by average distance) of urban buildings (7-
30 meters) and the proximity of the roadway (3-7
meters) was observed
An analysis of the state of contamination of rice crops
with red-grained forms was carried out, as well as
impurity was found both in the seed material and in
the soil. It was shown that there is a need to switch to
non-weeding seed growing technology when
conducting elite and reproductive seed production.
Various variants of soil cultivation in combating the
red rice forms are considered, both in the main and in
the pre-sowing treatment. It has been found that after
harvesting rice on heavily foul areas, it is better to
burn straw, and not to carry out autumn tillage of the
soil, the seeds of red-grained forms die mostly when
wintering on the soil surface. The most effective
method of soil cultivation for controlling of red rice
forms in seed crops has been identified, in which the
yield is increased, and the contamination of crops and
the resulting rice grain is significantly reduced. The
work carried out will allow reducing manual labor
costs in the production of seeds, improving their
quality and assortment, speed up variety changing and
variety updating
We have presented opportunities to improve the nutritional value of wine production: improvement of biogenetic soil, using organic fertilizers. The nutritional value is ensured by not only high-quality biochemical diversity of berries, but also the safety of products that do not contain toxic inclusions. Bio-fertilizer stimulates the biotransformation of toxic soil residues to replenish soil nutrients for the plant, providing grape raw material with biologically active substances and improves the nutritional value of wine products. Food safety of grapes is ensured by reducing it residues of hazardous chemicals migrating from the soil into the plant and the grapes. It has been established, that after 3 years of application of biofertilizers we significantly improved food safety and quality in the biochemical parameters, especially important for the classic wine grape varieties. The soil content of toxic residues in grape raw material is reduced to 50%, the amount of organic acids increases by: 4,22 mg/dm3(Gallic, coffee acid, chlorogenic; 0.7 g/cm3 amber; of 1.33 mg/dm3 ascorbic; 0.25 mg/dm3 nicotinic
The article scientifically substantiates and
experimentally confirms the high efficiency of the
nano biological feed supplement "NaBiKat" in diets of
broiler chickens of the "Cobb-500" cross. The
supplement is a new complex with a mixture of rice
germ films, green tea gallocatechin in chelated form,
and forty-nine trace elements in chelated form,
including biosoluble form of silicon. The main
function of silicon is to be involved in a variety of
intermediate exchange reactions as a catalyst and to
ensure normal flow of vital mechanisms as a coupler
helping to combine cellular molecules into a whole
functioning structure. Silicon begins to act on the body
when getting into the lumen of the gastrointestinal
tract with the feed. It activates the enzyme system of
the body and in ionic form is absorbed by kind of
ordinary diffusion along almost the entire small and
large intestine beginning from the jejunum. The
supplement studied has been proved to improve the
morphological structure and biochemical properties of
blood, to enhance metabolism, redox processes, and
the level of natural resistance. The broilers fed the
supplement "NaBiKat" in the experimental groups
have been found to have a higher concentration of
macro- and micronutrients in blood. The nano
biological silicon-containing supplement as a
compound of in the composition of feed for chickens
had a positive effect on their growth and development
In peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)
Currently, due to the risk of global warming because
of increased concentrations of greenhouse gases in the
atmosphere, carbon-deposit function of forest
ecosystems, thanks to which stabilization of gas
composition of the atmosphere takes place, has great
importance [1]. Forest is one of the main components
of the biosphere. Forests protect soil from erosion,
provide stability hydrological regime of rivers, supply
atmosphere with oxygen, biologically active
substances, purify of harmful impurities, create
optimal environmental conditions and play an
important environmental role. However, because of
intensive anthropogenic influence (unregulated
logging, technogenic environmental pollution
recreation) forest ecosystems are experiencing stresses
at which irreversible processes of degradation of
communities of economically valuable main forestforming
species of both natural and artificial origin
take place [6]. Evaluating carbon-deposit function of
forest plantations, CO2 emissions to the atmosphere
through the soil respiration must be taken into account,
which can vary within wide limits. Productivity of
forests is largely driven by carbon dioxide, released
from the soil. Soil carbon dioxide provides demand of
forest plants for photosynthesis. With increasing
intensity of soil respiration, positive balance is
maintained [2]. Based on the method of V.I. Tarankov
for evaluation of carbon-deposit and oxygen-producing
functions of wood cenoses [2], similar research is
carried out in RSI "Kuban forestry", the KarachayCherkessia
Republic
The steady development of modern pig farming
dictates the need for new priorities, opportunities and
requirements, such as reducing harmful environmental
impacts, more efficient use of resources, and provision
of comfortable conditions for the pig housing. The
creation of an appropriate ITS BAT in the branch will
optimize the activity of agricultural pig breeding
enterprises due to the transition to performance of
requirements based on BAT technological parameters,
to solve the problem of energy efficiency, import
substitution and increase of competitiveness. Their
integration will have an effect not only on improving
the ecological state of the environment, but also on the
economy of agricultural enterprises providing a new
approach to agricultural activity
The results of the study farm «Zavet Ilyicha» JSC,
Leningrad district of Krasnodar region, are presented
in article to study the role of rolling phosphorus in soil
samples, organic fertilizers and grain output of winter
wheat. We examined the relationship between the
content of phosphorus in the soil and fertilizers are
introduced and subsequently with the quality of the
harvest of grain. To receive high harvests of crops,
primarily need adequate amounts of phosphorus in
soils in an accessible form. The next important step is
the use of different fertilizers (mineral and organic)
under crops. Without the use of fertilizers cannot
return key for plants of nutrients, such as phosphorus,
nitrogen and sodium in the soil, since agricultural
products makes the nutrients. What dose of fertilizer
use and profitable forms of these fertilizers, solves
every household depending on culture, soil, climate
and economy. We received during the research the
following results: for 4 year average contents of
phosphorus in soils of agro-landscape in General, au
pairs amounted to 27.2–31.4 mg/kg. Average levels of
phosphorus in the soils crop rotation fields amounted
to 26.9 and 30.9 mg/kg. Maximum values amounted to
115.0 mg/kg, while the minimum is about 3.0 mg/kg.
Also conducted analyses on the contents of rolling
phosphorus in manure polupereprevshem pigs and
cattle. Marked by a very significant gap in content of
phosphorus, which is associated with significant
differences in their feeding. In grain of winter wheat
for 4 years, phosphorus content accounted for at an
average of 3.41 g/kg; minimum and maximum
performance from 2.35 to 4.47 g/kg, in 2012.
Compared with 2012 phosphorus concentrations in
grain of winter wheat has gradually increased to 2015,
and accounted for 3.47 g/kg with minimum and
maximum thresholds ranging from 2.05 to 4.89 g/kg
An experiment has been carried out on the effect of
germination of seeds with perlite on the improvement
of the growth force of rye Vyatka-2. The purpose of
the experiment was to study the effect of perlite on
the growth force of seeds under the conditions of
additional fertilizers and changing the volume water
during irrigation. The task of the work was to
determinate the growth force of seeds with perlite.
The growth force of the seeds was determined after
10 days in sprouted seeds in five samples in glass
vessels with three different moisture conditions. It
was proved that germination of seeds with perlite
increased the seed growth force up to 28% in
comparison with seeds grown in sand (a control
sample). The result also depended on decreasing of
humidity rate up to 30-40%
