type of forest site - Opis:
- The objective of the paper was to estimate i) the carbon accumulation in soils of different forest site types as well as ii) its changes with regard to the depth of the soil profile. The investigation was carried out in the Przedbórz Forest District (central Poland) on 43 study plots, including different forest sites – fresh coniferous forest (Bśw), fresh mixed coniferous forest (BMśw), fresh mixed broadleaved forest (LMśw) and fresh broadleaved forest (Lśw). On each plot soil pits were dug and samples for laboratory analysis were collected. The following characteristics were determined in the soil samples: pH, the content of organic C and total N, particle−size distribution, the content of exchangeable Ca, Mg, Na and K, and hydrolityc acidity. The obtained results demonstrated that soils of Bśw, BMśw and LMśw sites characterized by higher carbon accumulation in surface horizon to 50 cm depth compared to the most eutrophic sites (Lśw). The rate of carbon accumu− lation in forest soils depend on the humus type which is connected with species composition of stands. Domination of Scots pine in stand affects the formation of ectohumus and leads to higher C accumulation in surface horizons on Bśw, BMśw and LMśw sites. In soils of Bśw, BMśw and LMśw sites carbon stored in the horizons to 50 cm constitutes 64−94% of the total carbon accu− mulated, while on the eutrophic sites (Lśw) this share amounts to 39−72%. The value of the total carbon stock in soils of fresh forest sites can be estimated on the basis of carbon stock in horizons to 50 cm depth.
