THE EFFECT OF ABUNDANCE OF LITTERFALL ON RETENTION OF NITROGEN AND PHOSPHORUS IN ORGANIC HORIZONS OF FOREST SOILS IN THE SLOVINSKI NATIONAL PARK
Journal Title: Baltic Coastal Zone - Year 2011, Vol 15, Issue 15
Abstract
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 forest ecosystems was calculated. The nitrogen and phosphorus in organic horizons of Vaccinio uliginosi-Betuletum pubescentis have the shortest retention time (44 and 57 years respectively). The retention time of nitrogen and phosphorus in Empetro nigri-Pinetum are similar and counted about 62 years. The coefficient values of biological circulation show the strong inhibition of circulation of these elements, what caused reservation of matter in organic horizons and acidity of soil.
