Název v původním jazyce

Microbial utilization and transformation of humic substances extracted from soils of long-term field experiments

Popis výsledku v původním jazyce

Humic acids (HA) extracted with alkali from non-fertilised and fertilised (NPK + organic manure) plots of long-term, ie.45 years, field experiments were added as a supplemental source of nutrients or as the sole sources of carbon and nitrogen to semi-aerobic cultures of complex microbial communities indigenous to the same individual soils. Depending on the experimental conditions, between 2.7 % and 47.3% of the added HA preparations were utilized in 12 months. In full strength nutrient media these numbers seemed affected by some novel microbially produced HA-like substances. A average utilization rate was 33 % for the HA from an unfertilised orthic Luvisol plot, whereas HA preparations extracted fro fertilised plots of the orthic Luvisol or a dystric Cambisol soil site were utilised to 27 % and 15 %, respectively. The HA preparations re-isolated after 12 months from microbial cultures exhibited differences in elemental and structural characteristics, corresponding mainly with the nutri
