Název v původním jazyce

Microbial processing of humic acids extracted from soils of a long-term field trial

Popis výsledku v původním jazyce

Humic acids extracted with alkali from non-fertilised and fertilised (NPK + organic manure) soils of the field trials established 45 years ago were exposed to activities of a mixed population of indigenous soil micro-organisms in the laboratory. The individual cultures were kept on a rotary shaker for 21 days (aerobic conditions) or let standing for 12 months (semi-aerobic conditions) in order to determine the utilisation of HA as nutrients, and possible HA structural transformations. In a full-strengthnutrient broth HA positively affected the yields of microbial biomass, that, however, was strongly diminished if HA served as the only sources of carbon and nitrogen. In contrary, the utilisation of HA was up to 47.3% under semi-aerobic conditions in cultures deficient in easy utilisable sources of carbon (glucose). No substantial differences were observed in the microbial processing of HA from non-fertilised or fertilised soils.
