Characterization of soil organic carbon and its fraction labile carbon in ecosystems

Popis výsledku v původním jazyce

Organic carbon content and labile carbon content were determined in soils under different management systems. Soil samples were selected from the topsoil of the following soil types: Leptic Cambisol (Ocmanice, grassy soil), Haplic Cambisol (Náměšť n/Oslavou, arable soil), Eutric Cambisol (Vatín, grassy soil), Eutric Cambisol (Vatín, arable soil). Among the all parameters labile soil carbon and basal respiration activity were measured under laboratory conditions using Vaisala GMT 222 apparatus. Hot waterextraction for labile organic carbon determination was used. UV-VIS spectra were measured in the mixture of 0.1 M sodium pyrophosphate and 0.1 M NaOH. Results showed that total carbon content varied from 1.3 -- 1.8 %. Higher content was determined in grassy soils. Labile carbon content was higher in grassy soils to compare with arable soils (varied from 540 -- 620 mg/kg). HS sum was the lowest in grassy soil (locality Ocmanice) about 6.5 mg/kg. Quality of humus was low and HA/FA ratio w
