Abstrakt:

The content and relation between the amounts of macroelements (Ca, Mg, K, Na and Fe), and soil properties along three catenas in young glacial Łyna River valley, NE Poland are discussed in the paper. The results were presented on the background of four geochemical landscapes distinguished within the study area: eluvial / trans-eluvial, eluvial accumulative, trans-super-aqual and super-aqual. The average content of macroelements amounted to: Cat – 6.60 g kg-1 , CaHCl – 3.17 g kg-1 , Mgt – 2.79 g kg-1 , MgHCl – 0.68 g kg-1 , Kt – 7.27 g kg-1 , KHCl – 0.20 g kg-1 , Nat – 0.84 g kg-1 , NaHCl – 0.22 g kg-1 , Fet – 8.72 g kg-1 and FeHCl – 5.48 g kg-1. Content of macroelements in soils of the studied area was varied between the geochemical types of landscape. The analysis, supported by PCA ordination, resulted in significant positive relations between the macroelements contents and silt (0.05-0.002 mm) and clay (<0.002 mm) soil fractions, CaCO3, pHKCl and amounts of organic matter, as well as inverse relation to the share of sandy (2.0-0.05 mm) soil fraction. The most abundant in macroelements were soils in super-aqual geochemical landscape (except KHCl and Nat). The most typical sites of macroelements accumulation were the following geochemical landscapes: super-aqual > trans-super-aqual > eluvial accumulative > eluvial / trans-eluvial.
