| Popis: | Enchytraeid worms were kept in 0.3 mm (including the casts) was larger in the presence of enchytraeid worms, at the cost of soil from the fraction 0.3 0.03 mm. The %C in both soils was highest in the fraction < 0.03 mm. Activity of enchytraeids significantly decreased the %C in the fraction > 0.3 mm. Fresh excrements, representing 0.5% of the soil, were very high in organic matter content. Mineralisation (expressed as percentage of C that was mineralised) was highest in the fraction 0.3 ram. Aggregates > 0.3 mm from the treatment with worms dispersed less clay after shaking with water than those from the treatment without worms. Although the influence of enchytraeid worms on total C-content and mineralisation was small, the changes in C of the different size fractions showed that enchytraeids influenced the active fraction of the C in the soil considerably by consuming litter, thereby locating it inside soil aggregates and linking the organic matter to clay particles. |
