The effects of the fertirrigation were evaluated with in nature vinasse on to microorganism of the soil. The soil was treated with three levels different from in nature vinasse (equivalent to 200, 400 and 600m3.ha-1), withhumidity maintained around 70% of c.r.a.. Para isolation and count of the total microorganisms (bacterias, mushrooms and actinomicetos) and microorganisms celulolíticos were used the methods of the dilutions in series. The population of mushrooms had a significant increase with addition of the level of in nature vinasse of 200m3.ha-1, and the population of bacterias only obtained increase starting from the 120 days of incubation, tends larger growth in the level of vinasse 600m3.ha-1. The number of actinomicetos of the soil had a significant reduction in all the levels standing out the one of 600m3.ha-1, already with relationship to the population of microorganisms celulolíticos an increase of in nature vinasse 200m3.ha-1 was verified.
