Szukana fraza: [Abstract = "Subsequently, these samples were determined in the content of total carbon and the sum carbon from humic and fulvic acids on TOC\-VCSN Shimadzu. The study showed highly significant differences in the content of total carbon and carbon from humic and fulvic acids. Relations between total coal to coal from humic and fulvic acids exceed the value of 1.0 which may suggest a low level of mineralization of organic matter in studied soils."]
