 Abstract fertilization can be optimized and managed during the flu cured tobacco growing period by studying the response of soil and microbial biomass stone she metric characteristics to fertilization. In this study we investigated the effect of compound fertilizers combined with microbial fertilizer treatments on the stone she metric characteristics of the rhizosphere soil and the limitations of microbial resources during the flu cured tobacco growing period. The results indicated that soil and microbial C and tongue poking smiley varied greatly with the growing period. The effect of sampling time was usually greater than that of fertilization treatment and microbial C and tongue poking smiley did not vary with the soil resource stone she metric ratio. The microbial metabolism of the tobacco growing soil was limited by phosphorus after extending the growing period and phosphorus limitation gradually increased from the root extension to the maturation periods but decreased at harvest. The rhizosphere soil microbial nitrogen and phosphorus limitations were mainly affected by soil water content, soil pH, microbial biomass carbon and the ratio.
