METHOD FOR DETERMINING ECOLOGICALLY EXPEDIENT RATES OF NITROGEN FERTILIZERS IN TECHNOLOGIES TO GROW FARM CROPS

摘要

A method for determining ecologically appropriate rates of nitrogen fertilizers in technologies of growing farm crops includes simultaneous determination in dynamics of the activity of nitrogen fixation and biological denitrification while applying different rates of nitrogen fertilizers into soil. Potential activity of nitrogen fixation and potential activity of denitrification on roots of cultivated plants are determined.
