The influence of nitrogen mineral fertilizers, depth and growth phase of sugar beet on the number of microorganisms from nitrogen cycle was investigated. All the groups of microorganisms were found in a great number and mostly in the ploughing layer (0-30 cm). The nitrogen fertilizers had the positive influence on the number of microorganisms when they were applied at the levels of 30, 60 and 90 kg/ha while the level of 120 kg N/ha had the inhibitory effect. The higher number of microorganisms was found in the middle and at the end of the vegetation period. The positive coorrelation was found between the number of nitrogen-fixing bacteria and parameters for sugar beet quality
