Název v původním jazyce

Bio-available amino acids in soil under differently managed meadow ecosystems. 9th International Congress on Amino Acids and Proteins - Abstracts

Popis výsledku v původním jazyce

Our knowledge about bio-available amino acids in soil is fundamental for evaluation of nitrogen nutrition in different ecosystems as it is long since known that soil amino acids in their "free state" can be uptaken by mycorrhizal or nonmycorrhizal plantroots. This interest results from findings in boreal, alpine and arctic ecosystems where conditions are unfavourable to nitrogen mineralization and plant requirements cannot be satisfied by only mineral nitrogen. As soil amino acids pattern is influencedby plant coverage and soil properties we have performed an evaluation of concentrations of 17 bio-available L-amino acids, extracted by 0.5 M amonium acetate from mineral soil (Ah layer) of long-term moderately mown alpine meadow and eleven years abandoned part of the same meadow. The most abundant amino acids throughout the experiment were glutamic acid and arginin at both meadow plots. No significant (P>0.05) differences between concentrations each of the 17 amino acids on both stands
