The stimulating influence of the additional fertilizers “Akvarin 5" and urea on spring wheat yield formation is revealed in field experiments with spring wheat "Vavenkov Memory" in the Krasnoyarsk forest-steppe ordinary mould humus. The difference on grain productivity of these variants in comparison with control group is statistically reliable. The wheat grain nitrogen content increases in the variants with urea and “Akvarin 5" additional fertilizing and ammophos intra soil introduction.
