Selenium intake in plants in the conditions of southern forest-steppe of Omsk region

The article presents the results of examination of the peculiarities of selenium accumulation in plants of Astragalus galagoides and spring rape in the conditions of southern forest-steppe of the Omsk region on meadow-chernozem soil depending upon methods of its intake. The objects of research are spring rapeseed varieties Zolotoniski and Astragalus galagonidae.
