Abstract (en)

Biological nitrogen transformation was estimated in Gleyic Luvisols,Gleyic Albeluvisols and Calcaric Luvisols in ploughed (0–20 cm) horizon with intensive crop rotation in 2016. The balance of nutrients in soil is restored applying mineral fertilizers complex (1NPK (5-15-30+3) ir 2NPK (15-15-15+10)), thus, soil microbiological activity – applying biological stimulants. It was estimated, that fertilization and biological stimulants have been influencing the increase in microbial biomass. This could have an impact on spring barley (Hordeumvulgare L.) root biomass increase. As it was noticed, that in some fertilization cases barley root biomass increase was tendentious to microbial biomass increase. However, even soil microbial biomass and barley root biomass was increasing, biological nitrogen transformation was more nitrate nitrogen (NO3-N) related. The lower changes in NH4-N and NO3-N concentrations have been estimated in Gleyic Luvisols and in Calcaric Luvisols when 2NPK with biological stimulant was applied. Even that, the increase in concentration of NH4-N has been noticeable when mineral fertilizers are applied herewith biological stimulant.
