The largest volume of nitrogen and phosphorus in the litter of coniferous needles was found in early summer at the moment of maximum growth. An average concentration of nitrogen in examined needles was...
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...

For laboratory research two parcels were chosen, with the area of 0.5 ha, situated in protected district of Smołdzinski Las. The research of the selected parcels shows great differences in the construction of soil and flora profiles. What they have in common is the high level of groundwater,...
