Microbial floras in high-pH soils are dominated by bacteria, while in acidic soils fungi play a major role. Fungal mineralisation in the latter type of soil is known to be slower, but nevertheless nitrogen accumulation is observed. This may be explained by a lower uptake by the fungal community. The hypothesis will be tested by composing an experimental fungal / bacterial flora, containing selected strains from high- and low-pH soils isolated by both general and enrichment techniques. The nitrogen uptake of bacterial and fungal parts of the experimental flora will be studied using a solid carrier system.
