P.A. Chekmarev, S.V. Lukin, Yu.I. Siskevich, N.P. Yumashev, V.I. Korchagin, A.N. Khizhnyakov
Summary. On the basis of a solid agrochemical survey of arable soils, carried out by agrochemical service in Belgorod, Voronezh, Kursk, Lipetsk and Tambov regions, it was analyzed patterns of changing of mobile potassium content (according to Chirikov, State Standard 26204-91) in arable soils in Central Chernozem region over the past 45 years. Within CCR western and northern regions are the poorest in mobile potassium forms. The lowest weighted average content of mobile potassium forms (73.1 mg/kg) was fixed in soils  in Pichaevsk district of Tambov region, located on the North-East of CCR. In this district the percentage of middle supplied (41…80 mg/ kg) with potassium soil is the highest – 62.3 %. As a whole, the lowest weighted average content of mobile potassium forms is noted in Kursk (96 mg/kg), Lipetsk (101 mg/kg) and Tambov (102 mg/kg) regions, where the percentage of soils, middle supplied with this element, is 40.2, 33.0 and 23.8 % respectively, though soils with raised content of its mobile forms (81…120 mg/kg) dominate. Arable soils in Belgorod and Voronezh regions are characterized by the highest weighted average content of mobile potassium (127 and 123 mg/kg respectively). In Belgorod region the high content of mobile forms of this element (121…180 mg/kg) is characteristic for 36.1 % of inspected soils, and a very high one (more than 180 mg/kg) – for 11.0 % of inspected soils. In Voronezh region these indices are 43.9 and 6.8 % correspondingly. Such soils generally predominate in steppe zone, located on the East and South-East of those regions. In spite of enough stable content of mobile forms of potassium intake of this element in agricultural landscapes should be increased.

Yu. G. Сhendev, L. G. Smirnova, A.N. Petin, N.S. Kukharuk, L.L. Novykh
Summary. In the article by method of soil’s agrochronosequences results of humus content comparative analysis in chernozems with different ages of cultivation are given. Under the conditions of traditionally used agricultural engineering on the flat watersheds the maximum intensity of humus losses in Ap horizon (0,03-0,04 % of absolute contents annually) is observed for the first 50-70 years of plowing. Subsequently the intensity of dehumification reduces; however, losses of humus continue. For the prolongedly mastered (140-240 years) chernozems is revealed the tendency of reduction in speed of agrogenic dehumification of arable horizons and soil profiles in a number “leached chernozem – typical chernozem – ordinary chernozem”. In the south of Central Russian Upland the relationship of rates and volumes of average losses of humus in the arable soils of slopes with the same index on absolutely flat surfaces is evaluated as 3:1.

The influence of biologicals on the level of crop yield and quality of barley and clover depending on application of phosphoric and calcareous fertilizers
N.A. Kirpichnikov, A.А. Volkov
Summary.Influence of biopreparations on a productivity and quality of barley and clover depending on the phosphorus and lime fertilizers application Influence of phosphate mobilizing mycorrhizal biopreparation mycophil on the barley and nitrogen-fixing biopreparation rhizotorphin on the clover was investigated against the background of sod-podzol loamy soil. Plants were sown against the background of natural soil fertilization, as well as with liming and without it against the nitrogen-potassium background (N30K60) and on the back of complete mineral fertilizer application. In the latter case phosphorus fertilizers (P30) were applied in the form of double superphosphate and ground phosphate rock. In average for two years the effect of biopreparation mycophil for barley was 13…24 %, the most effect was observed in combination with ground phosphate rock and lime. Usage of rhizotorphin increased clover hay yield in all versions except control and nitrogen-potassium background, the effect was 8.4…17.9 %. The most influence of the preparation was also observed when using ground phosphate rock separately and in combination with liming (13.6 and 17.9 % respectively). The highest productivity of barley grain (41.3 c/ha) and clover hay (64.6 c/ha) under condition of experiment formed with superphosphate application with biopreparations usage against the background of limed soil. Nitrogen and phosphorus carry-over depending on the studied factors increased more than productivity, which is connected with a certain increase in the content of these elements in major and sideline products. So, when one applied mycophil in variant NK with ground phosphate rock, barley productivity increased by 24 %, nitrogen intake – by 32 %, phosphorus intake – by 40 %. Values of these indices for clover against the background of NK with lime with application of rhizotorphin increased by 12.3, 16, and 18 % correspondingly. The content of crude protein in grain changed from 9.1 % in control to 11.4…11.9 % when studied preparations used together; the content of protein in hay varied from 11.9 to 18.5 % against the limed NK-background. Biopreparations did not influence sufficiently barley and clover plants in control and NK-variant (without liming).

I.V. Rusakova, N.I. Vorobyev
Summary. In the laboratory (incubative), vegetal and field experiences were studied the influence of treatment the straw of different cultures (winter wheat, barley and lupine) by the biological preparation Barkon on the dynamics of the processes of its transformation in the soddy-podzolic sandy loam soil, the productivity of agricultural crops. In the incubative and field experiences is established the stimulating influence of the biological preparation on the microbiological processes of the transformation of the straw: an increase in the number of ammonifying microorganisms - to 10-58%, amylolytic - by 13-47%, aerobic microorganisms, which destroy cellulose tissue - to 33- 83%, the index of summary biological activity - into 1, 3 times, the coefficient of the humification of straw - to 52- 66%, the carbon content extracted by hot water - to 13-15, microbial biomass - on 115-130 mg/kg. The increase in the number of heterotrophic microflora was not accompanied by an increase in the summary emission CO2 in comparison with the version without Barkon, which can testify about the more active inclusion of organic carbon, introduced in the composition of straw into the microbial biomass and the humus substances. The addition of mineral nitrogen created the more favorable conditions of nitric nourishment for the soil microbiota, which participates in the decomposition of straw and ensured the maximum indices number of proteolytic and amylolytic microorganisms -respectively into 1,89-1,37 and 1,68 times higher than with the introduction of the straw of barley Barkon without the additions of nitrogen. In the vegetal experience Barkon inoculation of straw contributed to the elimination of its phytotoxicity. Thus, with the introduction into the soil of the straw, inoculated of Barkon the addition of the overground phytomass of barley composed 12- 13% with respect to the analogous versions without the biological preparation. The application of the biological preparation – gumifikator Barkon for treating the after-harvest remainders will make it possible to provide the condition for the more effective use of a noncommodity part of the harvest of cereal and leguminous crops (and also other withdrawals of plant growing) for the optimization of the humus state of arable soils.

L.I. Pusenkova, I.V. Maksimov, I.S. Mardanshin
Summary. In this article, we investigate the biological effectiveness of natural growth regulators with immonostimulant activity on potato plants. It was revealed that treatment plants with Fitosporin-M (biofungitsid), Gumi-20 (antistress preparation) and Borogum (bio-organic fertilizer) increase their adaptive capacity. The effectiveness of regulators increasing significantly under critical drought conditions. During the research a reliable increase in yield of tubers was noted in the variant of double treatment potato with biocomplex of Fitosporin-M and Gumi-20: 8.6% (2008), 29.5% (2009), 48.4% (2010). And, under drought conditions the effectiveness of drugs Fitosporin-M and Gumi-20 was higher when they were used separately. Inclusion of Borogum in the system of vegetative treatments of potato plants is most effective under stress conditions for plant growth. We studied biopreparations provided a significant yield increase (from 36.4 to 80.3%) under drought conditions. The highest biological effectiveness in protecting tubers from diseases (72%) was observed in the variant of double treatment potato with Fitosporin-M and its composition with Gumi-20.

A.S. Zubkov
Summary. As result of tree-year studying of zero,surface, shallow and medium depth subsoil methods of tillage and conventional plowing under barley on a private farm when the tillage methods were used once in a crop rotation with the application of herbicides and mineral fertilizers as the background it has been established that their effect is not of unequivocal character. Surface, shallow and medium depth subsoil methods of tillage as compared with conventional plowing has not any essential effects o the content of effective moisture in a 50 cm soil layer (maximum difference is eight mm), mobile forms of nutrients in the arable layer, grain protein content, grain coarseness, germinating ability in the mass of 1000 grains. Maximum difference in a number of indexes was observed between the treatments without primary tillage and plowing. The use of the first tillage method leads to the in-crease of plant residues amount on the soil surface three times, increase of weed infestation of crops, first of all perennial weed infestation, 0.43 times, decrease of plant stand density by the harvest time by 13 % , drop of grain natural weight by 7 %. However such influence when the tillage method is used once does not always tell negatively on grain yield, especially in unfavourable by weather conditions years, and naturally on economical and energy efficiency of the method. The conducted studies allow to recommend widely for the conditions of the Central Chernozemic Region besides plowing surface, shallow and medium depth subsoil methods of tillage as primary soil tillage.

DNA-technology in selection of agricultural animals 
A.F. Jakovlev, M.G. Smaragdov, V.S. Matjukov
Summary. The estimation of breeding value was and remains the most difficult stage in cultivation of agricultural animals and, in particular, dairy cattle. The problem of an estimation of breeding value of an animal consists that for its definition it is necessary to compare and analyse communication between selection signs at ancestors, lateral relatives, descendants and the animal. The analysis of polymorphism of single nucleotides of DNA of all genome gives the chance to reveal communications of loci of quantitative signs with thousand markers and to raise reliability of an estimation of breeding value of animals from 30-40 % to 60-90 % and at the expense of reduction of an interval of generations and cost of check of bulls on quality of posterity to accelerate genetic progress. Technologically molecular genetics, biometry, cybernetics, and biotechnology have given keys to fast hereditary transformation of breeds and populations of agricultural animals. However the understanding of the remote genetic consequences of revolutionary change of population gene pool while lags behind rough progress of technical possibilities. Therefore it is necessary to aspire to receive the qualitative information on intraspecific genetic differentiation and the differentiated selective value of population gene pool by means of new means.

Stimulative and inhibitive effect of the natrium hypoclorite on the microbiom and somatic cells of the mice organism 
D.D. Gomboev
Summary. The aim of the research was to determine the conditions of predominance of stimulatory and inhibitory action of sodium hypochlorite on the microbial and somatic cells of animals. With insufficient amounts of protein (peptone) - breeding in 5 and 10 times the standard environment MPA hypochlorite inhibited the growth of test culture E.coli. Constant hypochlorite watering of mice by the end of 1.3 weeks influenced on the weight which decreased from 25 to 19,1 ± 0,5 g. The muscle strength and functional activity of the intestinal microflora also decreased. Watering hypochlorite twice a week did not affect the microflora, but increased the secretion and activity of lymphoid cells of submucosal layer of the intestine. Thus, the basic condition for the small increase of microorganisms by the action of sodium hypochlorite, is a small concentration of protein in the culture medium. After constant hypochlorite watering the inhibition of normal intestinal microflora occures, disbiotic phenomenon develops. Twice a week hypochlorite watering helps to increase the functional activity of intestinal microflora and intestinal syncytium.

Method of calculation and detection for closing-to-land mode with phase wire breakaway in countryside 10 kv networks 
A.N. Klochkov
Summary. In countryside 10 kV networks one-phase-closing-to-land mode can be dangerous for human and animals and often transforms into two phase short circuit mode. Usually one-phase-closing-to-land mode calculating with symmetrical components but this method is useless for modes with several unlike damages. The goal of our research is to increase reliability of countryside 10 kV networks by improving calculation methods and signal devices for one-phase-closing-to-land modes. In research modeling of networks with isolated neutral using method of phase coordinates was made. For calculation of asymmetrical network modes electric scheme divides on some parts. All parts represents as 2K-pole elements in H or Y form where K is number of phases or wires. According to calculation principles which were made in Kostroma agricultural academy it is recommended to consider ground as fourth wire not connected to current source. In that way potential of ground will depend on connection order in scheme and current in ground will be restricted by line capacity. Results of calculation for branchy network are determine dependence of null sequence voltage 3U0 and network parameters in form of regression: 3U0(Zt,Ld,Zz,Ls)=55,2093–0,0014⋅eZt–0,11224⋅eLd–0,00074⋅ eZz–0,08276⋅eLs, where Zt, Zz, Ls and Ld – real factor meanings. In summary to increase reliability of countryside 10 kV networks it is necessary to decrease threshold of closing-to-land signalization and use new protection devices.
