aref2 The research purpose is to reveal energy efficiency of micronutrient fertilizers application under winter grain crops on meadow-chernozem soil of the Omsk Region. The research subjects include winter wheat variety Omskaya 4, rye variety Sibir 3, meadow-chernozem soil, and micronutrient fertilizers. Application of zinc on the background of 60 promoted increase of energy efficiency of fertilizers application in winter wheat cultivation (where the bioefficiency amounted 4.01 in the variant 60Zn4), and in winter rye cultivation (4.87). Without zinc fertilizers application the bioefficiency of phosphoric fertilizers was less - 3.60 and 3.10 accordingly. At powdering of seeds by trace elements the bioefficiency of phosphate-potassium fertilizers application P60K60 under winter crops changed from 1.56 to 4.00. Thus the application of Zn50Cu50Mn50 under winter wheat and Zn50Mn50 under winter rye contributed to the highest bioenergy efficiency of P60K60 fertilizer; in both cases bioefficiency amounted to 4.0. Energy costs of obtaining 1 ton of incremental product (grain) by means of fertilizers decrease in more effective variants from the point of view of energy efficiency of fertilizers application. The application of increasing doses of zinc fertilizers at basic application under winter wheat on phosphoric background (P60) reduced energy costs of 1 ton of grain from 4558 to 3806 mJ alongside with bioefficiency increase from 3.60 to 4.32. Similar regularities were also observed at combined application of macro-fertilizers and micronutrient fertilizers by powdering of winter wheat and winter rye seeds.
