In the conditions of the Republic of Belarus there was studied the agronomic efficiency and influence of new forms of micro-fertilizers on production processes, crop yield and grain quality of spring wheat (Triticum aestivum). As a result of realized research it was found that the maximum accumulation of dry matter at application of various preparations to a phase of milky-wax ripeness was observed on the average for 2007-2008 in variants N70P60K90 + N30 urea ammonium nitrate with Cu (735.0 g/100 plants) and N70P60K90 + N30 urea ammonium nitrate with Ekolist in a booting stage (719.0 g/100 plants). On the average for 2007-2008 on a background of N70P60K90 + N30 application of compound micro-fertilizers of Ehkolist and Vitamar increased productivity of spring wheat grain on 3.3 and 4.6 c/ha. In these variants it was observed the greatest productivity of grain (51.1 and 49.8 c/ha). The highest content of crude protein on the average for two year in spring wheat grain (15.9%) was noted at topdressing with cuprum on a background N70P60K90 + N30 urea ammonium nitrate and application of Vitamar on a background N80P80K130+N45+N25. In variants with application of Vitamar gathering of crude protein was maximum (6.7 c/ha).
