Abstract
Metodama mokrog i suhog spaljivanja određene su koncentracije organskog ugljika u poljoprivrednim tlima kako bi se potvrdila usporedivost i podudaranje rezultata dobivenih primjenom tih metoda. U tu svrhu uzorkovano je i analizirano 12 uzoraka na području Osječko-baranjske i Vukovarsko-srijemske županije. Svaki uzorak analiziran je u triplikatu. Određivanje organskog ugljika metodom mokrog spaljivanja temelji se na spaljivanju organske tvari tla pomoću koncentrirane sumporne kiseline i kalijevog bikromata koji služi kao jako oksidacijsko sredstvo. Određivanje organskog ugljika metodom suhog spaljivanja temelji se na spaljivanju uzorka tla u prisutnosti kisika na visokoj temperaturi. Primjenom regresijske analize dokazana je usporednost dviju metoda za određivanje organskog ugljika u poljoprivrednim tlima s koeficijentom determinacije R2 = 0,9619.
Abstract (english)
Wet and dry combustion methods were used to determine organic carbon concentrations in agricultural soils in order to confirm the comparability and matching of the results obtained using these methods. For this purpose, 12 samples were collected and analysed in the Osijek-Baranja and Vukovar-Srijem county. Each sample was analysed in triplicate. The determination of organic carbon by the wet burning method is based on the burning of soil organic matter using concentrated sulfuric acid and potassium bichromate, which serves as a strong oxidizing agent. The determination of organic carbon by the dry burning method is based on the burning of a soil sample in the presence of oxygen at a high temperature. By applying regression analysis, the comparability of two methods for determining organic carbon in agricultural soils was proven with the coefficient of determination R2 = 0.9619.
