Standards improvement for determination of winter wheat requirement in the mineral fertilizers

Method of nutrients doze determination for agricultural crops according to recoupment standards of the mineral fertilizers elaborated by ARSRI for agrochemistry by harvest of grain crops rise is presented in article. As opposed to basic methods this one allows to establish scientifically based yield to each field in dependence ofagrochemical properties and determine nutrients doze and it recoupment by harvest rise, forecast economic efficiency of mineral fertilizers.

Keywords: fertilizer dozes, fertilizer profitability standards, planning yield, economic efficiency.

Elemental composition of oats beans grown in the Middle Cisurals

Studied the elemental composition of the oat grain Konkur. Found that the elemental composition of the grain depends on weather conditions vegetation period. Regarding the highest content of chemical elements observed in a more favorable meteorological conditions vegetativeyear. The heavy metal content does not exceed the maximum permissible concentration, and the resulting products are recommended for the production of dietary products.

Keywords: оat, elemental composition, meteorological conditions.
