Changes in the Physical Properties of Precipitation in Pine Stands in the Area with A Low Degree of Air Pollution (Western Pomerania)

Abstract

Abstract. The study presents the results of research conducted in the years 2010-2012 in pine stands in Western Pomerania. The research included physicochemical properties of bulk precipitation and throughfall. The results confirm that despite a decrease in the total throughfall in the interception process, the size of mineral and organic depositions in pine stands exceeded values recorded for bulk precipitation. 2-, NO 3 -). The share of leaching processes for K + was 74.1%, while for Mg 2+ 23.6% of the total load of these elements brought to the ground with throughfall. In the case of Ca 2+ no canopy leaching was observed for this element. The throughfall acidification processes were mostly caused by NO 3 -.
