The aim of the study was to assess the trophism of soils in the strict nature protection area using the soil trophic index (SIG). The ‘Rybitew’ strict protection area (224.2 ha, created in 1965), is located in the north−eastern part of the Kampinos National Park (central Poland). The results of field and laboratory studies of the physicochemical and chemical properties of soils made it possible to...
Organic matter and nitrogen content was analysed in genetic horizons of Dystric Cambisols in the Kabacki Forest (Warsaw, central Poland). Particle size fractions in investigated soil indicated the following contribution in binding of organic matter: 0.1−0.02 mm – 7.6%, 0.02−0.01 mm – 13.2%, 0.01−0.005 mm – 18.8%, 0.005− −0.002 mm – 21.9% and <0.002 mm – 37.8%. Sand fractions with 1−0.1 mm particles...
W poziomie orno-próchnicznym - Ap badanej gleby zostało zgromadzonych w poszczególnych frakcjach od 54,0 do 72,6%, a średnio 63,5% całego humusu zawartego w profilu glebowym do głębokości 125 cm. Pozostały zapas humusu został zgromadzony w poszczególnych frakcjach poziomu Bbr i C zalegających na głębokości od 25 do 125 cm. Frakcje < 0,02 mm wiążą średnio 89,5% całości humusu glebowego, w tym frakcja...
The average concentration of titanium in the alluvial soils of central Vistula was: 0.29% (ranging from 0.05-0.49) and from the Żuławy area 0.42% (ranging from 0.29-0.50), while in the clay fraction of all soils was: 0.43% (ranging from 0.29-0.49), respectively. The investigated soils contain natural amounts of titanium which can be accepted as a geochemical background. The element content correlates...
The pedogenic process of humus accumulation causes stronger and more diverse chemical rather than physical transformations of quartz grain surfaces. Chemical weathering of quartz grain surfaces in the humus horizon results in etching and corrosion over oncrusting and encrusting; an opposite situation is observed in the parent rock and the underlying rocks. Etchings and corrosion pits in the humus...
Badania przeprowadzono w 4 profilach gleb brunatnych intensywnie użytkowanych, wytworzonych z płytkich lessów Równiny Błońsko-Sochaczewskiej. Trzy profile gleb zaklasyfikowano jako gleby brunatne wyługowane, a jeden jako brunatną właściwą. Zawartość rozpuszczalnej formy Zn, Cu, Pb, Cd oznaczono w 0,1 M HCl, a podstawowe analizy gleb wykonano powszechnie stosowanymi metodami w laboratoriach gleboznawczych...
