In the main collectors in the North-West Caspian we have found the concentration of priority chemical elements: in water - Zn, Cu, Mn, Co, B, Mo, Cr, Ni, Pb; in sediments - Zn, Cu, Mn, Cr, Ni, Pb. It was found that a common and characteristic feature of drainage water is a low concentration of these elements investigated (except Mn, B, Pb). In the bottom sediments collectors content of gross forms of Zn, Cu, Mn, Ni, Pb and mobile forms of Zn, Cu was below the MRL and the content of the gross forms of Cr and Mn mobile forms was a little higher
In the article, the results of the researches of total evaporation, the modes of irrigation and the productivity of corn on grain in the conditions of a steppe zone of the Republic of Northern Ossetia-Alania are presented. The empirical dependences characterizing relationships of cause and effect in system: “hydroweather conditions - an irrigated agrobiocenosis”, allowing to improve methodology of irrigation planning and to increase accuracy of irrigation planning, taking into account existential variability of climatic factors are presented
There was described the history of rice growing branch formation on Kuban from thirties to eighties of XX century: from first sowings to the production of a million ton of rice. The role of academician E.P.Alyoshin in the development of Kuban rice growing was marked. There were shown the ways of rice harvest increase on Kuban at present time
The article presents the purposes and priority directions of development of improvement of water complex of agrarian and industrial complex according to Water strategy of agriculture of Russia for the period till 2020. It also analyzes water supplies of the Krasnodar region with planned development of improvement of water economic complex. It presents the conclusions for the further water economic works in a basin of Kuban river
The article describes two common methods for assessing the sustainability of the grape varieties to the harmful organisms: domestic [1, 4] and the international OIV [7]; the table of the comparative indicators of sustainability for these methods and the results of the evaluations of 24 varieties zoned in the Krasnodar region has been presented
Methodological aspects of conduction of researches on study of regeneration activity of grape cuttings by students of secondary schools including by members of Small Agricultural Academy of Kuban are cited in the article
The article presents results of studying total content
of titanium in both not fertilized and systematically
fertilized black leached soil. Science-based system of
fertilizer crop rotation allows solving problems of
sufficient balance of nutrients in the system of "soilplant-fertilizer",
increasing the quantity and
improving the quality of the crop. At the same time,
their application is active influence on the natural
environment. In the soil, there is an input of a large
set of chemical elements come along with fertilizers.
In addition, due to their physiological pH or
alkalinity, fertilizers are capable to affect the physical
and chemical properties of the soil. The use of
mineral fertilizers in scientifically based doses on the
fields of crop rotation for 33 years virtually has no
impact on the content of titanium in leached
Chernozem. In the arable layer its number increased
only by 2.1 %, and in subsurface - it is the same as in
the crop without fertilizer. Enrichment of topsoil with
titanium is due to desilication of rocks during
weathering. Due to the low solubility of titanium
minerals, they remain in the place longer, and
therefore, the content of the element in the soil
increases. As you know, fertilizers applied to the
fields of crop rotation, increase the intensity of the
biological cycle of substances and thereby enhance
the process of destruction of the parent rocks

The article presents the results of studying the ways to
preserve biologically active substances in raw
pumpkins
The article presents the results of obtaining functional feed additive based on secondary plants (tomato pomace and corn mash) in the preservation of their lactic acid bacteria strains
