In the conditions of the Republic of Belarus there were presented results of influence of a complex water-soluble fertilizer Akvarin 8 (produced in Russian) on productivity and quality of grain of spring wheat (Triticum aestivum) cultivated on agrarian sod-podzolic sandy soil. The analyzed fertilizer had the following composition (%): N – 19; P2O5 – 6; K2O – 20; Fe – 0.054; Mn – 0.042; Zn – 0.014; Cu – 0.01; B – 0.002; Mo – 0.004. Trace elements of metals in the fertilizer were presented in chelate form, boron – in organo-mineral form. In course of the study in grain of the spring wheat there were studied the main quality indexes: crude protein content; gluten; and gluten deformation index. Research results showed that application of the Akvarin 8 as a foliar top dressing in dose 6 kg/ha in different phases of plant development (a tillering, a flag leaf, a heading beginning) in course of 2 years rendered positive impact on crop yielding capacity. The highest effect was observed after Akvarin 8 application in three terms.
