Chemistry of Raw Humus Vs. Chemistry of Atmospheric Precipitation on the Example of Pine Forests of the Pomeranian Lakeland

This research, conducted for the purposes of the protection of the National Park Bory Tucholskie, contains the results of the investigation of the chemical composition of humus (forest litter) and of atmospheric precipitation. The gathered material allowed determining the fate (accumulation or removal) of chemical elements contained in the pine forest humus as well as to compare the abundance of nutrients in humus and in atmospheric precipitation.
