摘要：

A significant positive correlation between the concentration of CFU of soil saprophytic microfungi and total soil carbon content, organic matter (oxidizable carbon) and available phosphorus was observed in field collected soil samples. Concentration of CFU of culturable bacteria correlated negatively with soil organic matter. Specific length of hyphae of arbuscular mycorrhizal fungi in the soil correlated only with soil respiration rate. The results indicate that arbuscular mycorrhizal fungi are associated with soil microsites rich in some easily mineralizable fraction of soil organic matter rather than with total or oxidizable organic carbon.
