Abstract
Provedeno je istraživanje utjecaja predtretmana spaljivanjem organske tvari tla (OT) na rezultate analize mehaničkog sastava tla (MST). U tu svrhu, određen je MST u 20 uzoraka slabo humoznih tala, i to sa i bez prethodnog spaljivanja OT 30% vodikovim peroksidom. Za disperziju uzoraka tla na mehaničke elemente, korištena je otopina natrijevog heksametafosfata i natrijevog karbonata. Statističkom obradom rezultata, utvrđeno je da postoje značajne razlike u rezultatima analize MST, obzirom na primjenu/izostanak uklanjanja OT. Međutim, te su razlike u apsolutnom smislu bile male te u pravilu nisu utjecale na određivanje teksturne klase tla. Stoga, izostavljanje uklanjanja OT iz uzoraka slabo humoznih tala može biti opravdano ako se ne zahtijeva visoka preciznost analize MST, nego samo pouzdano određivanje teksturalne klase tla.
Abstract (english)
The effect of soil organic matter (SOM) removal on the results of soil particle size distribution (PSD) analysis was investigated. Soil PSD was determined in 20 samples featuring low SOM content, with and without prior removal of SOM with 30% hydrogen peroxide. For the dispersion of soil samples, solution of sodium hexametaphosphate and sodium carbonate was used. After statistically processing the results, it was found that there were significant differences in the results of the PSD analysis, given the application/absence of SOM removal pre-treatment. However, these differences were small in absolute terms and generally did not affect the determination of the soil textural class. Thus, omitting SOM removal in samples with low SOM content may be justified, if it is not the high precision of PSD analysis that is required, but only the reliable determination of soil textural class.
