Vztah mezi obsahem nízkomolekulárních organických kyselin v půdách a bohatostí bylinného patra karpatských bučin

Popis výsledku v původním jazyce

Low molecular mass organic acids (LMMOA) are a part of the carbon cycle, and represent an important component of the active organic carbon in soil. The aim of this study was to determine the content, speciation and behavior of LMMOA in soils under Carpathian beech forest with different herb vegetation (herb poor, herb rich), and to assess the relationship between herb vegetation cover and LMMOA. We hypothesize, that LMMOA can influence herb vegetation richness through their (LMMOA) ability to release nutrients in forests soils. Speciation of LMMOA, nutrition content (PO43-, Ca2+, K+) and element composition in aqueous extracts were determined by means of ion chromatography and inductively coupled plasma,optical emission spectrometry (ICPOES) respectively. Sorption characteristics were determined in BaCl2 extracts by ICP-OES. Active, exchangeable pH and DOC (dissolved organic carbon) were also determined. Elemental composition of parent rocks was assessed by means of X ray fluorescence spectroscopy.
