Description
  • Cílem této studie bylo porovnat úroveň heterotrofního respiračního potenciálu (VDS/VMAX) a maximální respirace indukované aplikaci glukózy (VMAX) v organominerální půdě (Ah horizont v klasifikaci FAO) na permanentně mírně kosené louce a 11 let opuštěné části teze louky v Moravskoslezských Beskydách. VDS/VMAX je možno definovat jako poměr mezi úrovni mineralizace C po vysušení a následném ovlhčení pudy na 60 % aktuální vlhkosti (v/w) (VDS) a VMAX. Oba studované parametry byly srovnávány ve 30-ti denních intervalech sezony roku 2004 (kveten-září 2004). Výsledky teto práce ukázaly vyšší VDS/VMAX na opuštěné louce po celou doby experimentu kromě posledního studovaného měsíce (záři). Na opuštěné louce bylo stanoveno vyšší VMAX po celou dobu experimentu. Významné (P<0,05) vyšší VDS/VMAX na opuštěné louce bylo stanoveno v měsících květnu a červenci, VMAX bylo na teze louce významné (P<0,05) vyšší pouze v září. Čas odběru vzorků neměl významný (P>0,05) vliv na VMAX v Ah horizontu mírně kosené louky. Na o (cs)
  • In this study, heterotrophic respiratory potential (VDS/VMAX) expressing an increase in C mineralization rate after drying and re-wetting the soil to 60 % soil water content (w/w)(VDS) in relation to maximum respiration rate (VMAX) after glucose addition, and VMAX in organomineral soil (Ah horizon) of moderately mown and for 11 years abandoned mountain meadows in Moravian-Silesian Beskids Mts was compared. VDS/VMAX and VMAX was assessed in soil samples taken in 30 days intervals throughout the period of May - September 2004. The results obtained showed higher VDS/VMAX on abandoned meadow throughout the whole experiment except the last sampling occasion, and higher VMAX throughout the whole experiment. Significantly (P<0.05) higher VDS/VMAX on abandoned meadow was found in May and July, VMAX was on the same meadow significantly (P<0.05) higher only in September. From the studied parameters, the time of sampling had no significant (P>0.05) effect on VMAX when data from moderately mown meadow were evalua
