| Description
| - 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 %22free state%22 can be uptaken by mycorrhizal or nonmycorrhizal plant roots. 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 influenced by 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 were found

- Znalosti o biologicky přístupných aminokyselinách v půdě jsou důležité pro hodnocení dusíkaté výživy v rozdílných ekosystémech, protože tzv. %22volné%22 aminokyseliny mohou být přijímány mykorrhizními nebo nemykorrhizními kořeny rostlin. Zájem o danou oblast vychází z poznatků získaných v boreálních, alpských a arktických ekosystémech, kde podmínky prostředí znevýhodňují mineralizaci dusíku a požadavky rostlin na dusík nemohou být zajištěny z minerálních forem N. Složení půdních aminokyselin může být ovlivněno složením rostlinného pokryvu a půdními vlastnostmi. V této studii jsme uskutečnili experiment, ve kterém jsme porovnávali koncentrace 17 biologicky přístupných L-aminokyselin v minerální půdě (Ah horizont) dlouhodobě mírně kosené a 11 let opuštěné části téže horské louky. Ze 17 aminokyselin byly na obou částech horské louky v nejvyšší koncentraci stanoveny glutamová kyselina a arginin. Koncentrace individuálních aminokyselin na obou částech horské louky nebyly statisticky významně rozdílné (P>0.05) (cs)
