Occurrence of Azospirillum spp. in the rhizoplane of wheat, barley and corn fertilized with mineral N, organic fertilizers (slurry, manure) or mixed fertilizers was investigated. It was observed that mineral nitrogen in amounts 80, 120, 160 kg per ha results in elimination of Azospirillum from rhizoplane of barley and wheat. The same effect on bacteria in the rhizoplane of barley and corn was caused by slurry in dose 170 and 340 kg N per ha. An application of mineral fertilization with manuring reduced an disadvantageus effect of high rate mineral nitrogen on Azospirillum.
