Název v původním jazyce

Behaviour of aluminum in forest soils with respect to content and speciation of low-molecular-mass organic acids (LMMOA)

Popis výsledku v původním jazyce

The aim of this study was to determine the content, distribution and relationship between Al and LMMOA in soils under beech forest, and to assess the effect of herb vegetation on it. Different soil horizons were sampled separately, organic L, F, H, organomineral A, and mineral B horizons. Al forms, available (AlH2O, water extractable) and exchangeable (Alex, 0,1 M BaCl2) and speciation of LMMOA in water extract were determined. Principal soil properties, pH, major cations and anions, dissolved organic carbon etc. were also determined. The exchangeable soil reaction was the lowest in H horizon, there was also the highest amount of Alex. The highest content of LMMOA (lactate, oxalate) was found in all organic horizons. We can hypothesize that LMMOA mobilize Al from mineral fraction and this Al consequently occupies soil sorption complex. Generally we can conclude that LMMOA and thus soil vegetation cover play important role in Al soil cycle.
