In the conditions of the Republic of Belarus there was studied the agronomic and economic efficiency of application of a new liquid complex fertilizer 'Kapustnoe', which contained macroelememts, trace elememts and physiologically active substances (nitrogen mass fraction -6.6%; potassium mass fraction K2O – 3.67%; phosphoros mass fraction – 0.78%; magnesium mass fraction – 0.70%; total boron mass fraction 0.71 gram/cubic decimeter; zinc mass fraction 0.24 gram/cubic decimeter; copper mass fraction 0.12 gram/cubic decimeter). The experiment was realized by the example of plants of white cabbage (Brassica oleracea convar. capitata var. alba L.) of Kolobok variety. The carried-out researches and calculations showed that application in not root top dressing of new liquid complex fertilizer Kapustnoe promotes significant increase in indicators of agronomical and economic efficiency of cultivation of cabbage (productivity and profitability level raises). The given fertilizer increases productivity of cabbage on 77 c/hectares and increase profitability of cultures cultivation on 44,5% in comparison with fertilizers application system used in a facilities.
