ABOUT ABILITY OF KUBAN LEACHED BLACK SOIL TO DEACTIVATE ESPECIALLY DANGEROUS HEAVY METALS

abstract 0611007004 issue 61 pp. 31 – 44 24.09.2010 ru 1998
The results of studying of the maintenance of lead and cadmium in soil and agricultural crops at use of various agrotechnologies are presented in the article. The negative tendency of accumulation of heavy metals in winter wheat grain is noted

ABOUT DISTRIBUTION OF CONNECTIONS OF Mn, Cu, Zn, Co, Pd AND Cd IN THE SOIL PROFILE OF THE BLACK LEACHED SOIL OF THE AZOV-KUBAN LOWLAND

abstract 0951401047 issue 95 pp. 854 – 873 30.01.2014 ru 1136
In this article the influence of agrotechnologies of cultivation of field cultures on soil indicators and distribu-tion of heavy metals on the horizons of the black leached soil is considered. Regularities of distribution of gross and mobile forms of manganese, zinc, lead, cobalt, copper and cadmium on the genetic horizons of the black leached soil of the Azov-Kuban lowland are revealed

ECOLOGICAL AND AGRONOMIC EVALUATION OF THE INFLUENCE OF CHEMICAL FARMING MEANS ON YIELD AND QUALITY OF WINTER WHEAT GRAIN

abstract 1311707115 issue 131 pp. 1405 – 1424 29.09.2017 ru 385
The proposed agro technology for the cultivation of soft winter wheat contributes to the reproduction of fertility of leached Chernozem of the Western Ciscaucasia. As a result of application of fertilizers in the arable layer of soil hydrolytic acidity decreased by 21.8%, humus content increased by 10.3%, mobile phosphorus - by 54.8%, mineral nitrogen by 10.3% and potassium - by 9.6% compared to the control. Studied agricultural technology allowed to increase the yield of winter wheat to 81.8 kg/ha and protein to 15.3 per cent, of gluten, to 27.8%. We have noticed exceeded concentration of mobile phosphorus in the upper soil horizon (1.5 MРС) in the cultivation of wheat after alfalfa, which contributed to reduced grain yield. Under conditions of prolonged application of fertilizers and pesticides reduced the content of mobile forms of trace elements - copper and zinc. The content of mobile forms of Mn, Cu, Zn, Cr, Ni, Co, Pb and Cd below the limit values of environmental and Toxicological regulations clayey and loamy soils for agricultural purposes. The trend of accumulation of cadmium in the green mass of plants (~ 1.2 MPC) and winter wheat grain up to 1.5 MPC for baby food

INTERRELATION OF VARIOUS FORMS OF COMPOUNDS HEAVY METALS IN AN ARABLE LAYER OF EARTH AND THEIR ACCUMULATION IN GRAIN OF WINTER CROPS

abstract 1111507042 issue 111 pp. 737 – 757 30.09.2015 ru 644
In the article we consider the influence of agricultural technologies of cultivation of winter crops on existence of various forms of heavy metals in an arable layer of earth in the conditions and their accumulation in grain production. The gross content of compounds of copper in an arable layer of black leached soil is above background values (maximum concentration limit 1,5-1,7), a share of the fixed connections makes 75 %. The gross content of zinc exceeds background value for chernozems (1,25 clark). The correlation of the water mode of the soil and the content of mobile compounds of heavy metals in an arable layer - a straight line for Cu and the return for Mn , Pb, Cd and Co. Supplement of an arable layer of earth with mobile forms of copper, zinc and cobalt low, manganese - corresponds to the average level. Speaking of the degree of actual mobility the studied elements settle down in sequence: Cd> Mn> Co> Pb> Zn> Cu. Degree of potential availability decreases among: Zn> Mn>Pb> Co> Cu. The existence of Mn, Cu, Zn and Co in grain of wheat is lower than maximum concentration limit, and accumulation of Pb and Cd is higher than maximum concentration limit in grain production for baby food for 10-15 %, that increases individual risk of death to the maximum permissible level
