PRODUCTIVITY FORECAST OF BROWN FOREST SOILS FOR TEA CULTIVATION IN ADYGEA BASED ON MODERN EVALUATION METHODS

abstract 1191605015 issue 119 pp. 227 – 237 31.05.2016 ru 925
Increasing of tea production in the foothills of Adygea should be based on potential soil properties suitable for tea plant. The goal was achieved using modern methods of soil evaluation of tea plantations. The evaluation criteria were the following agrochemical and agro indicators: soil acidity (pH KCl); hydrolytic acidity; the sum of exchangeable bases; bases saturation; granulometric composition. It was found that the soil under tea plantation in Adygeya classifies as brown forest poorly unsaturated with the level of potential fertility rated as satisfactory (bonitet rating 40-60). However, the low supply of nutrients in the layer 0-40 cm: phosphorus (19,04 ± 2,42 mg / 100 g soil), potassium (17,70 ± 1,60 mg / 100 g soil) and a sufficiently high degree of saturation of soil bases in the layer of 50- 100 cm (67,10 ± 11,67%) in combination with a soil moisture deficit determine their low productivity of 16,0 ± 5,0 kg / ha, whereas their potential productivity of 30-50 t / ha. The development of scientifically grounded, targeted ameliorative and agro-technical measures (irrigation, nutrition systems using physiologically acidic forms of nitrogen and potash fertilizers that reduce the degree of saturation of the soil bases) will help to increase the effective soil fertility and allow the tea plants reach its biological potential and achieve predicted productivity in Adygea region

ON IMPROVING THE ACCURACY OF FILLING GEODETIC NETWORKS OF QUADRANGLES

abstract 1021408009 issue 102 pp. 185 – 192 31.10.2014 ru 1097
The article considers the issue of increasing the accuracy of filling geodetic networks of quadrangles with measured by the parties by increasing the number of conditional equations. We have considered the three variants of placement of additionally measured diagonals of the squares. The results improve the accuracy in the determination of coordinates of points within the network, due to these additional measured elements

The chemical composition of neogen-quaternary, paleogene, cretaceous and paleozoic aquifer systems in the Ob-Tomskoye interfluves area is presented in the article. The water saturation with respect to secondary minerals is described. Authors show that the waters of all studied aquifer systems are saturated with respect to montmorillonites and calcite in a less degree. The geochemical water types are identified and their distribution is described

INTEGRATED ASSESSMENT OF COMPLEXITY OF ENGINEERING AND GEOLOGICAL CONDITIONS OF THE TERRITORIES OF THE KRASNODAR REGION

abstract 1211607129 issue 121 pp. 2031 – 2044 30.09.2016 ru 1997
One of the main problems at engineering-geological researches is the choice of the most suitable territory for construction of designed projects and constructions. The most dangerous threat to the economy and the security of the Krasnodar region are geohazards. The article provides an expert evaluation of engineering-geological conditions of the territory, the map-scheme of evaluation of engineeringgeological zoning of the region. The characteristic is given to the engineering-geological taxons allocated on degree of usefulness of conditions

INFLUENCE OF FEATURES OF ENGINEERING-GEOLOGICAL STRUCTURES ON PROBLEMS OF RESEARCHES AT ARRANGEMENT OF OIL AND GAS FIELDS

abstract 1061502054 issue 106 pp. 853 – 866 28.02.2015 ru 1398
Prospects of development of oil-extracting branch of the Krasnodar region are connected with continuation of prospecting works and search drilling in a zone of transit of the Kuban River and water areas of the Black and Azov seas. In the existing normative documents about technical researches we didn't find reflection of the rule of works on platforms of capital construction of wells on the earth and in transitional conditions. The technique of studying of engineering-geological features of territories of oil and gas fields is offered. Regional and zone factors of engineering-geological conditions of oil and gas fields are established. Engineering-geological structures are allocated. Additional types of technical researches are defined

HYPOTHESIS OF THE ORIGIN OF THE UNIVERSE, SOLAR SYSTEM AND EARTH

abstract 1181604013 issue 118 pp. 223 – 244 29.04.2016 ru 883
It is assumed that in the primordial state of the Universe was missing the elements of matter, it was submitted to electromagnetic photon field in a broad frequency band. Photons with energy ε=1,02 born MeV electrons and positrons, and photons with energy ε=1,87 born ÐœeV protons and antiprotons. The Association of protons, electrons and essential spectrum of photons created a sustainable hydrogen atoms and neutrons. Association of hydrogen atoms led to the creation of hydrogen clusters, and merging neutron – neutron creation of clusters (pulsars). As a result, the concentration of photons in the Universe decreased and the universe were compressed. The gravitational interactions between the hydrogen and neutron clusters was coming off of a mass of matter from both. The torn mass of hydrogen clusters were created on the planet. Separation of the mass from neutron clusters led to the neutron exposure of the main hydrogen clusters and loose parts from him (future planets). The latter, being closer to the main hydrogen accumulation, under the influence of neutron flux were redesigned to all elements of the periodic table. The article describes nuclear reactions convert one chemical element to another. After irradiation of the primary hydrogen clusters of neutrons and the emergence of the heavy and superheavy hydrogen, started fusion reactions with the release of photon energy and the transition of hydrogen clusters in Stellar condition. They began to glow. The selection of the photon energy of the Stars led to the increase in the concentration of photons in the Universe, the increase of the pressure and the expansion of the Universe, which is what happens at the present stage of its development. Combining antiprotons, electrons (positrons) with the required spectrum of photons created sustainable antihydrogen and antineutrons, and their clusters – clumps of antimatter in the Universe

HOW TO ESTIMATE THE ACCURACY OF DETERMINING THE COORDINATES IN THE APPROACH OF HANSEN

abstract 1171603010 issue 117 pp. 192 – 203 31.03.2016 ru 1106
Recently, there have been satellite-based methods widely used to determine the coordinates of points, which allow, without mutual visibility between points, to pursue their coordinates. However, in some cases, for example in forests, in urban buildings the application of these methods becomes a problem and it is easier to apply traditional methods. The article describes the case of using the method of calculation of coordinates for "the approach of Hansen" and held to evaluate the accuracy of determining the coordinates of the points. Some studies provide only recommendation guidelines that the most accurate results are obtained when the shape of the building is shaped similar to a square. In our case, on the basis of obtained formulae we had an analysis of the influence of the length of the corresponding base, and its distance from the source side on the accuracy of determination of coordinates of the original points. The conclusion is that the accuracy of determination of coordinates of required points depends on the ratio of the length of the original basis and the baseline. The optimal can be considered the distance equal to 0.3-0.6 of the length of the baseline. The holding data in the study can successfully be used for the drafting of geodetic reference polygonometries moves and thickening of networks
