Opis:: The studies were carried out in central Poland. Total organic carbon (Corg), total nitrogen (Nt) andCof humus fractions in uppermost soil horizons were analyzed in afforested meadow soils in first and fifth year of afforestation (2 profiles) and compared to about 70-year-old continuous forest soils. Soil was collected from 0-5, 5-10, 10-15 and 15-20 cm layers depth. The results showed that the soil Corganic (Corg) and Ntotal (Nt) decreased with depth in both studied periods. The Corg amounts were higher in the second period (5 years after afforestation) in almost every layer of the humus horizons in comparison to the first year of afforestation. The Nt content rather decreased in particular layers during five years, but mean values of 0-20 cm depth were lower or higher in dependence on soil type. The content of both elements in the studied layers was lower in the 5-year afforested soils than in the continuous forest soils. The results indicated changes in organic matter properties too, but the distribution of the different soil organic matter fractions in humus layers in time was dependent on soil properties.

Opis:: The study has been carried out in the experimental field of the Centre for Ecological Research of the Polish Academy of Sciences, PAN, located in Dziekanów Leoeny (north of Warsaw). Six hundred lysimeters were installed covering the experimental area. The surface of the experimental plots (both lysimeters and their vicinity) was sown with either one grass (Festuca rubra) on half of the area, or with a mixture of 8 grass species on the other half of the area. In the next year, geophagous earthworms A. caliginosa were introduced to half of the lysimeters. The content of C-org, N-total, and the fractional composition of soil humus, were first determined at the beginning; at the end of the experiment also pH and the capacity of sorption complex were identified. The empirical results were subject to statistical analyses. After two years of the study, in comparison to red fescue sodding, the grass mixture sodding caused an increase in the content of organic carbon, total nitrogen and carbon of the humus fraction. The differences between the mean values of both soddings were not statistically significant. In soils under grass mixture, A. caliginosa caused an increase in the contents of organic carbon and fulvic acids carbon in relation to the initial soil; the CHA/CFA ratio significantly decreased. A slight increase in the degree of organic matter humification was observed in both soddings in combination with earthworms.
