English title: Soil oxygen conditions in paludifying boreal forest sites

Tiivistelmä

Soil oxygen conditions were characterized with the help of polycarbonate tubes, which were filled with water and inserted into the soil. The oxygen content of the water inside the tube was measured and compared with that in conditions of full aeration. Five forest sites were studied. Three of them form a moisture gradient — mesophyte spruce forest (MSF), paludifying spruce forest (PSF) and paludified pine forest (PPF). For comparison, three other sites were included: a dry pine forest (DPF), an alder carr mire (ACR) and an ombrotrophic bog. Soil aeration conditions were the most unfavourable at the PSF site at the beginning of June; the lowest values being recorded in depressions with Sphagnum girgensohnii. Considering the whole vegetation period, the bog site demonstrated the lowest soil aeration level. At the alder carr site, soil aeration conditions were dependent on precipitation. In forest sites the lowest aeration level was observed at the beginning of June, but in the ACR and bog sites, another minimum occurred in September after heavy rains. Keywords: Coniferous forest, oxygen conditions, paludification, succession

Avainsanat
