DescriptionIn 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

DescriptionIn the conditions of middle valley of the Lena River on the cryogenic, inundated, cespitose and chernozemic soils different steppe communities differently react on dietary regime. Herb-grass phytocenosis at organic dietary regime is reformed in cereal phytocenosis with the contents of cereals to 76% and bean types 19% of dry basis with productivity to 20 centner of hectare of dry basis. At the same time the efficiency of the improved phytocenosis was on charge exchange energy of 17,3 mega joule of hectare, feed units 1032 and a crude protein of 247 kilo of hectare. The whetgrasses phytocenosis has provided productivity to 19,4 centner of hectare and the content of perevarimy protein in 1 feed unit up to 118 gram. So the most effective for the steppe meadows is using complex fertilizer (humus of 20 tons of hectare + N60P60K60), increasing the productivity twice with a high quality of food

DescriptionThe optimal rations have been found. We have conducted a research on the assessment of meat productivity, biochemical blood tests. The chemical composition of blood and meat has been found. We have empirically chosen a content area for both chicks and adults of black African ostriches. The article shows a selection of optimal rations for feeding of ostriches; we have also determined the live weight of ostriches in groups, keeping the chicks safe in groups, hematological studies of ostriches blood, the chemical composition of the meat, the efficiency of premixes of Vitafel S
