Nitrogen use by plants and nitrogen flows after application of standard and biomodified nitrogen fertilizers on barley

The aim of our study was to assess the efficiency application biomodified nitrogen fertilizers for barley, reveal sources used biomass formation with use 15N stable isotope, and flows in system fertilizers–soil–plants–atmosphere. We demonstrated a model experiment ability plant growth-promoting bacteria Bacillus subtilis Ch-13 move from granules mineral roots colonize them effectively. effectiveness Nur variety, assessed microfield trial. After fertilizers, accumulation plants increased by 2–5 %, its incorporation soil decreased gaseous losses were 7 % as compared usual forms fertilizers. can be agricultural practice novel technology regulate
