Description
  • Změny biologických a chemických vlastností půdy jsou způsobeny jak vlivy vnějšího prostředí, tak i vnitro-půdními činiteli. Každý půdní typ má vlastní dynamickou rovnováhu mezi obsahem minerální a organické části, mezi stabilizací a aktivací organických a minerálních látek. Při stanovení souboru ukazatelů pro hodnocení uvedených vlastností vycházíme ze skutečnosti, že každý půdní typ má v procesu pedogeneze dány charakteristické vlastnosti půdního sorpčního komplexu (PSK), zásobu humusu i jeho specifické složení a rozdělení v profilu. Vzorky byly odebrány z ornice na následujících lokalitách jižní Moravy: černozem modální (lokalita Bořetice), černozem karbonátová (Březí), černozem lužní (Dubany), černozem degradovaná (Kašenec), černozem modální (Ostrožská Lhota), černozem modální (Prace), černozem modální (Syrovice) a černozem modální (Želeč). Měření bazální respirace čerstvě odebraných vzorků probíhalo v laboratorních podmínkách, kde mohou být podmínky vnějšího prostředí přesně kontrolovány a stano (cs)
  • Soil organic matter (SOM) undergoes short and long-term transformation in the soil. Microorganisms through their enzymes are able to mineralize organic carbon while the rate of this process is different. Biological test though referred to one of the main diagnostic methods for evaluating soil quality/health. The aim of our work was to determine basal respiration, total carbon content, fractional composition of humus and basic parameters of soil colloidal complex in selected subtypes of chernozem in south Moravia region. Basal respiration was measured using Vaisala GMT220 apparatus. Total carbon content was determined by oxidimetric titration and basic parameters of soil colloidal according to Mehlich. Results showed that production of carbon dioxide varied from 0.09 to 0.27 mg CO2/100g/h. Linear correlation between basal respiration and humification degree was found. Humus content varied from 2.15 % to 4.6 %. No correlation between quantity of humus and basal respiration was observed. Higher values of
