Every year forest soils are enriched with nitrogen and phosphorus compounds due to the fall of leaves and litter of conifer needles, mineralization of ground cover and decaying tree roots, as well as precipitation. The process has been examined in two forest ecosystems: a mixed forest (plot I) and a young wood (plot II). The overall fall of duff collected in the young wood of the Słowinski National...
The paper presents results of research into organic horizons and litterfall in two different forest ecosystems: Vaccinio uliginosi-Betuletum pubescentis and Empetro nigri-Pinetum in 2003-2005. On the basis of the amount and abundance of litterfall and abundance of organic horizons in the nitrogen and phosphorus compounds retention time and biological circulation coefficient of these elements in researched...
The paper presents seasonal changes in the concentrations of ammonia, nitrate and phosphate ions in podzolic soils under the Vaccinio uliginosi–Betuletum pubescentis and Empetro nigri-Pinetum plant communities. It results from the conducted investigations that the distribution and accumulation of mineral forms of nitrogen and phosphorus are considerably affected by atmospheric conditions such as temperature,...
The study on properties of proper podzol soils was carried out in two different forest ecosystems: Vaccinio uliginosi-Betuletum pubescentis and Empetro nigri-Pinetum in the Slovinski National Park (17o15΄E, 54o44΄N). Analysed soils are acid and strongly acid, with soil pH decreasing with the depth of the genetic soil horizon. Average soil moisture content is significantly related with contents of...
