Forest vegetation affecting the deposition of atmospheric elements to soils

Abstract

Atmospheric inputs of elements/ions into the soil through bulk precipitation and throughfall (precipitation below tree canopies) were monitored monthly at two forested catchments (Lesni Potok and Liz) in central and southwestern Bohemia, respectively. The annual deposition fluxes (expressed in µg/mg m −2 yr −1 ) of Al, As, Ba, Be, Ca, Cd, Cl It is declared that high fluxes of these elements/ions in TH significantly affect the forest soil water chemistry and that the forest vegetation significantly contributes to the mobilization of several elements in soil and to their redistribution throughout the soil profile.

Evaluation and indirect estimation of nitrate losses from the agricultural microbasin Rybárik

“…These processes show significant seasonality (Moldan et al 1994). The problem of transport of soluble and insoluble compounds to the streams is further complicated by human activities that influence the natural processes and modify the abundance of particular elements in the ecosystem (Lenhart et al 2003;Zhang & Schilling 2006;Fišák et al 2006). Pekárová & Miklánek (2005) and Pekárová et al (1999) showed the development of nitrate concentrations in the Mošteník basin (Slovakia), and the nitrogen balance and modelling of its agricultural subbasin, Rybárik, and forested subbasin, Lesný, during the period 1988-1992.…”

Comparison of Models for Spatial Distribution and Prediction of Cadmium in Subtropical Forest Soils, Guangdong, China

“…Cadmium in soils can be derived from the underlying bedrock, transported parent material (e.g., glacial till and alluvium), or aerial deposition and sewage sludge, manure, and phosphate fertilizer application [7]. Many factors, such as geological formation processes, climate conditions, soil formation factors, and interactions among soil-plant systems, can affect Cd distribution along the landscape or soil profile [4,13,20,21]. A study on the distribution of toxic metals down to the BC or C horizon of soils at 95 locations among five forest production regions of Switzerland suggested that most toxic metal contamination originated from the parent rock [22], while anthropogenic input was detected in most topsoils.…”

Meteorological situations in 2007 and their implications for the cycling of selected chemical elements in a Central Bohemian forested catchment

“…This conspicuous difference was caused by the low discharge in 2007, when the soil water persisted for a longer time within the soil solid matter which was therefore better saturated with major base cations coming from weathering and exchange processes (Navrátil 2003;Navrátil et al 2003). Higher pH also reflected the considerably lower input of atmospheric acidifiers, in particular when compared with those in the last years of the 20 th century (Skřivan et al 2000b;Fišák et al 2006).…”
