In the Republic of Belarus the assortment of applied micro fertilizers expands due to recent application of chelates of trace elements. The chelate forms of micro fertilizers in light doses provide maximal plant productivity. In course of the research there was studied the influence of foliar nutrition with sulfurous cobalt and manganese salts, complexonates of these microelements on content of microelements in green mass and grain of blue lupine (Lupinus angustifolius) cultivated on sod-podzolic light loamy soil. The field experiment was realized in the conditions of the Republic of Belarus in 2006-2007 on sod-podzolic light loamy soil. As a result of realized research it was revealed that the highest content of cobalt in yield observed during the foliar fertilizing with cobalt chelate in a dose of 50 g/ha of active ingredient in the end of flowering phase – the beginning of grey beans formation. The foliar fertilizing with manganese chelate in a dose of 50 g/ha of active ingredient in the end of flowering phase – the beginning of grey beans formation promoted the maximum accumulation of element in plants of blue lupine.
