| Abstract | Cilj rada bio je utvrditi postoje li statistički značajne razlike između kalkokambisola povrh vapnenca i kalkokambisola povrh dolomita na području NP Plitvička jezera. Na području parka otvorili smo 30 pedoloških profila od kojih je 18 bilo na vapnencima i 12 na dolomitima. Na otvorenim pedološkim profilima po horizontima su uzeti uzorci tla te je određena skeletnost po horizontima, kao i debljina pojedinih horizonata i ukupna dubina cijelog profila. Zajednica Lamio orvalae-Fagetum se dominantrno pojavljuje na vapnencu, a Helleboro nigri-Fagetum na dolomitu, dok se zajednica Omphalodo-Fagetum podjednako pojavljuje na oba tipa matičnog supstrata. Najveće razlike u ektomorfološkim parametrima između vapnenaca i dolomita utvrđene su klasifikaciji stjenovitosti i kamenitosti, gdje se na vapnencu ona kreće u rasponu od vrlo niske do vrlo visoke, dok je na dolomitu nema. Uzorci tla odneseni su na fakultet te je na svima određen je granulometrijski sastav, zatim pH reakcija tla odnosno pH-vrijednosti u vodi i otopini CaCl2, na uzorcima čija je pH-vrijednost u CaCl2 bila veća od 5,5 određen je i udio karbonata u tlu, udjela organskog i ukupnog ugljika i ukupnog dušika metodom suhog spaljivanja te na kraju udio makro- i mikroelemenata. Dominantna teksturna oznaka kalkokambisola povrh vapnenaca je praškast glina dok je kod kalkokambisola povrh dolomita praškasto glinasta ilovača. Od endomorfoloških značajki statistički značajne razlike su u dubini A horizonta, skeltnosti u B horizontu, udjeli krupnog i sitnog pijeska u A i B horizontu, a udjel gline u A horizontu je pokazao statistički najveću razliku. U kemijskim svojstvima pH u vodi se statistički značajno razlikovao u oba horizonta, a pH u CaCl2 samo u A horizontu. Udio totalnog dušika se statistički značajno razlikovao u B horizontu. Kod makroelemenata statistički značajna razlika je bila kod udjela biodostupnog kalija u A horizontu, dok se udjel magnezija očekivano statistički značajno razlikovao u oba horizonta. Od istraživanih biogenih mikroelemenata jedino se statistički značajno razlikovao udjel bora u A horizontu kalkokambisola povrh dolomita u odnosu na kalkokambisole povrh vapnenca. |
| Abstract (english) | The purpose of this research was to determine if there are statistically significant differences between calcocambisols over limestone and calcocambisols over dolomite in the area of Plitvice Lakes National Park. In the park area, we opened 30 pedological profiles, with 18 on limestone and 12 on dolomite. Soil samples were taken from the open pedological profiles by horizons, and the skeletal content by horizons, as well as the thickness of individual horizons and the total depth of the entire profile, were determined. The community Lamio orvalae-Fagetum predominantly occurs on limestone, while Helleboro nigri-Fagetum occurs on dolomite. The Omphalodo-Fagetum community appears equally on both types of parent substrates. The greatest differences in ecomorphological parameters between limestone and dolomite were found in the classification of rockiness and stoniness, which ranged from very low to very high on limestone, while it was absent on dolomite. Soil samples were taken to the university, where the granulometric composition, pH of the soil reaction, pH values in water and CaCl2 solution were determined for all samples. For samples with a pH value in CaCl2 higher than 5.5, the carbonate content in the soil, the content of organic and total carbon, and total nitrogen by dry combustion method were also determined. Finally, the content of macro- and microelements was determined. The dominant textural classification of calcocambisols over limestone is powdery clay, while for calcocambisols over dolomite, it is powdery clayey silt. Among the endomorphological features, statistically significant differences were observed in the depth of the A horizon, skeletal content in the B horizon, the proportions of coarse and fine sand in the A and B horizons, with the clay content in the A horizon showing the greatest statistical difference. In terms of chemical properties, pH in water showed statistically significant differences in both horizons, while pH in CaCl2 was significant only in the A horizon. The total nitrogen content showed statistical differences in the B horizon. Among the macroelements, the content of bioavailable potassium in the A horizon showed a statistically significant difference, while the magnesium content was expectedly statistically significant in both horizons. Of the investigated biogenic microelements, only the boron content in the A horizon of calcocambisols over dolomite showed a statistically significant difference compared to calcocambisols over limestone. |
