METHOD FOR THE ESTABLISHMENT OF THE DEGREE OF NITROGEN SUPPLY OF WINTER SOFT WHEAT

摘要

The method is used for balancig the nitrogen content in the grain produced from the reutilization nitrogen quantities of the vegetative mass, from its direct penetration in the soil and the consumption capcity. There is an opportunity to adjust the growing systems of wheat in every field, in particular the amount of nitrogen fertilization and reduce the soil and ground water pollution. By the method the optimum nitrogen concentration in the straw is deerminged which ranges from 0.9 to 1.1%.
