EFFICIENCY OF SELENIUMCONTAINING NITROGEN FERTILIZERS AT CULTIVATION OF SPRING WHEAT ON SOD-PODZOLIC LIGHT LOAMY SOIL
Abstract
The efficiency of new forms of selenium-containing nitrogen fertilizers for optimization of selenium content in a grain in the field experience with spring wheat cultivated on sod-podzolic light loamy soil has been studied. It is found that selenium-containing nitrogen fertilization under spring wheat has not substantial influence on yield increase but promotes the accumulation of this element in grain harvest up to the optimum concentration by introduce selenium in KAS in doses 0,25 and 0,3 5 kg/ha and in urea - 0,05-0,25 and 0,35 kg/ha.
