DESCRIPTION OF CERTAIN ASPECTS OF THE PRODUCTION POTENTIAL OF SOILS TAMAN PENINSULA
DescriptionThe work presents the results of the scientific research in the Taman Peninsula soil properties. We carry out the historic review of the studies in the Taman Peninsula soils, and its geological structure. We present morphological characteristics of the soil profile for the southern, calcareous, ultra heavy loam chernozem developed from the loessial loams and forming genetic horizons. The studies of the humus content in the soils show the associations between its percentage and the type and intensity of the agricultural use. Studies of the soils structure and composition demonstrate marked aggravation of the soils physical properties caused by grape growing. The best results of the particle size analysis have been achieved for the woodland soils. In woodlands, after their establishment, the soils under the grass and crown layers develop free of the anthropogenic impact. We register self-supporting growth of organic matter and natural processes of soil fertility recovery; therefore, such soils are characterized with a greater content of organic matter as compared to the soils under grape plantings cultivated in the monoculture regime. Reduced soil organic matter (humus) content in vineyards results from the disturbed biological interchange of the matter and increased anthropogenic impact causing erosion processes

CHANGES IN ORDINARY CARBONATE CHERNOZEM CONDITIONS CONSIDERING MODERN HYDROMORPHISM
DescriptionThere are changes in almost all the properties of chernozems under locally overmoistening. In general, changes in the properties and conditions of chernozems under the development of local wetlands went in a particular way, regardless of the peculiarities of soil formation factors and causes waterlogging. The most noticeable change is the transformation of physical properties of soil and organic matter status. According to our research, more quickly and clearly excessive moisture causes a change in the physical properties of the soil. There are changes of the structural state, bulk density and amount of water-stable aggregates. The significant change is the transformation of soil organic matter. There is increasing of total humus content. In a group composition, the fraction of humic and fulvic acids increases the share. The humus profile is stretched. In the majority of cases in investigated soils was diagnosed secondary salinization. The periodic waterlogging of the soil also contributes to the change in the amount of soil carbonates and their distribution in the profile. Chernozems gradually lose calcium, the main structurant and humates maker. Among the most studied soil of Zernogradsky region in the cationic part of the prevailing spot goes sodium. In addition, the narrowing ratio of calcium to magnesium was observed. That is the hallmark of the aqueous extract of locally overmoistening soils

INTRODUCTION OF RHODIOLA ROSEA L. IN THE CENTRAL YAKUTIA
DescriptionThe flora of Yakutia is rich in medicinal plants. Many of these plants are not still studied totally. The species Rhodiola (Crassulaceae) is one of the most popular family which are widely used by the local population for therapeutic purposes. Medicals use the rhizome and roots of Rhodiola rosea as a source of medicinal raw materials. This means the removal and destruction of plants. The procurement should be carried out solely on the basis of plants grown in culture because of the rarity and few natural reserves of the species. R. rosea L. passes a full cycle of the sprouts, blossoming and bearing fruits during the introduction in the conditions of Central Yakutia. The weather conditions of the year influence on the rate of development and growth processes very strong. The experiments determination of the germination of local reproductions were negative. The sprouts grow very good. In this case, it is good possibility of intense vegetative reproduction of Rhodiola. The evaluation of stability of introduction may be attributed to the kind of group stability. The great potential and adaptive capacity of R. rosea significantly enhances the possibility of growing this species under conditions of the Central Yakutia. It is recommended to improve and elaborate of protection of natural populations and unique plant communities

PROPERTIES OF FOREST SEED SAMARA, WITHOUT PTERYGOID APPENDAGES, LEGUMES AND WITHOUT PERICARP
DescriptionProperties of forest seeds are the basic and initial data for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the legumes, and also to substantiate constructive, technological parameters and operating modes of seed-cleaning machines. So far, there are not enough full information about the technological and mechanical properties of forest seeds, this makes it difficult substantiation and developing new technologies and technical means, in particular, to separate the seeds from samaras hardwoods and extracting legumes from the leguminous trees. The article presents the results of studies of technological and mechanical properties of forest seeds with samara and without pterygoid appendages: Norway maple, ash and elm ordinary, as well as legumes: honey locust, white acacia, acacia yellow and pure seed. Were studied: weight of 1000 seeds, volume weight, mass and volume coefficients, angle of repose, the coefficient of static friction and the coefficient of dynamic friction of the various working surfaces, holding strength samaras to forest seeds and strength of legumes pods. The data obtained are used for substantiate technology and technical means constructions, to separate the seeds from the samaras and extraction them from the pericarp

PERSPECTIVES OF DEVELOPMENT OF AGROLANDSCAPES IN THE STEPPE ZONE OF EDGE
DescriptionStudies of ecosystems allow estimation of difficult processes (physical, chemical and biological), taking place in them and determine how to manage them. At the heart of the natural systems there are freely interacting populations of different taxons, productivity of their above-ground structures, details of which are quite limited, and as underground systems, the data have even less information. In the late 60s and early 70s in the XX century a lot of information appeared associated with problems of environment, its pollution, lack of energy of food resources, clean water; it determined the root cause of the reaction of the population of developed countries on the aggravation of relations between society of people and habitat. Existed for a long time the concept of the exploitation of nature, which reflected on using soils, forests, water and other sources and which showed the power of mankind and its technical power over nature. In reality, this concept was just a common strategy of aphids sucking their environment. Understanding the real situation on the different levels of consciousness of the population defined situation of practical and scientific research in the field of ecology of different directions - chemical, biological, mathematical and other sciences. Development of ecology today will evolve to meet conservation and sustainable development of the biosphere, which experiencing constant anthropogenic pressure. An important problem of agrolandscape systems is an objective assessment of their productivity. Among the issues that determine the development of agricultural systems there are the natural conditions and soil fertility, crop dynamics over the years, the duration of the growing season of individual taxons, as well as the possibility of create of mixed crops, different type of life form, ecological features, physiological diversity of biochemical characteristics. Sowings this type allow, under certain conditions, obtaining stable yields under any climate dynamics and significant reduction of soil erosion. Combined sowing that is practiced in South East Asia, particularly in China, where the main components are the soybean and corn. The usefulness of mixed crops is the stability of yields over the years and the ability to emphasize their resistance to dry weather conditions
