The 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

The ecological state of soil on the globe is unstable. Intensification of agricultural production is accompanied by negative trends in changes in soil fertility. One of the most important indicators of soil fertility is its structural state. With a long time cultivation of grapes in one place, the physical properties of the soil deteriorate. The purpose of our research is to study the process of destruction of soil structure during the cultivation of vineyards. The object of research is the soils of plots of various agricultural uses (vineyards, field crop rotation, forest belts). The research methods used in the work are route-field surveys, a laboratory study of the waterphysical properties of the soil. The article presents the data of the structural-aggregate composition of the soil from plots of various agricultural uses. From the data given, it can be seen that the soil occupied by the vine plantations is characterized by a poor structure and low structure of the arable horizon. The share of agronomically valuable aggregates is 40.4%, the structural coefficient is 0.68 units, while in the forest belt this figure is 5.7 units. The increased mechanical load on the soil during the cultivation of vineyards leads to a deterioration in the physical properties of the soil. Soil with low indicators of physical condition is more susceptible to erosion processes, such as water and wind erosion. Water erosion annually causes great damage to agricultural lands throughout the world. The article clearly demonstrates and scientifically substantiated the negative effect of the system of soil content of vineyards on the type of black steam. Also proposed are ways to reduce the mechanical load on the soil and prevent the development of degradation processes in the soils of vineyards

Grapes are product of areas. Grape plant is very plastic and can grow on almost all types of soils except highly saline, fusion and wetlands. In studies of many authors, it was indicated the influence of different soil types and their properties on the growth of the vine plants, the quality of berries and their products. The object of study is soils and vines growing on them, laws and processes affecting the formation of grape production. Research methods are expeditions, field and laboratory. The article presents data on the effect of agrochemical soil properties (pH, solid residue, the amount of aqueous extract ions, chlorine ions, alkalinity (НSO3¯), calcium ion, magnesium ion, total carbonate, active carbonates, nitrate nitrogen, mobile phosphorus, exchangeable potassium , humus, humus reserves) on the formation of the harvest of grapes and wine products (tasting score, the extract, the amount of phenolic compounds, the amount of organic acids, the amount of amino acids, metal ions, potassium ions, sodium metal, magnesium ions, calcium ions, the amount of metal ions). With the help of statistical data, we can establish the effect of weather conditions on the formation of 2009-2011 qualitative wines of Cabernet Sauvignon

In the article the effects of examinations on influence of a vascular necrosis on a survival of shanks of grapes of breed Saperavi inoculated on stock RхR 101-14 are introduced

One of the limiting factors to obtain high yields of grape plantations in Anapa-Taman subzones with good quality is moisture. Grape plant adapts well to a limited amount of moisture in the soil. The penetration of roots deep into the soil horizons may reach 5-6 meters, provided with a moderate density of the soil and the lack of limiting factors such as the presence of ground water and limiting the content of toxic soluble salts. In the course of mathematical data processing we have established a trend of increasing average annual rate of precipitation in the period from 1932 to 2015. In the years when the amount of precipitation for the year exceeds the average long-term performance, the key amount of precipitation in the summer months in a downpour and in a limited area. Average annual amount of precipitation in the period from 1932 to 2015 was 519 mm, the minimum was recorded in 2002 (324 mm), the maximum - in 1981 (800 mm). Despite the general trend of increasing average annual rainfall over the years, moisture deficit is in the soil. Accounting of moisture saving dynamics in the soil in the 2015-2016's indicates the absence of moisture reserves. Optimal soil moisture values were observed only in May and June, and only half meter layer of soil. In the phase of growth and ripening berries (July, August, September) soil moisture content was much lower than the permissible value, which is comparable with the level of wilting point. For the stable-quality grape raw materials it is necessary to pay more attention to the water and the air regime of the soil
