Název v původním jazyce
A proposal of new indices for soil microbial ecotoxicology
Popis výsledku v původním jazyce
A classical chloroform fumigation-extraction method (CFEM) was carried out to obtain 0.5M K2SO4 extracts of fumigated (F) and non-fumigated (NF) samples of 36 grassland and 12 forest soils from Czech Republic. Main physical and chemical properties of soils were also determined and basal respiration (BR) of soils was measured. Organic C in extracts was determined by dichromate digestion. Anthrone-, orcinol-, and phenol-reactive C (ARC, ORC, and PRC, respectively), ninhydrin-reactive N (NRN), Folin-Ciocalteu's reagent-reactive compounds (FRC), and diphenylamine-reactive compounds (DRC) were assessed in extracts using colorimetric analytical methods. The methods used were found to be quick, simple and cheap. By this way biochemical specification of soil organic matter and microbial biomass was gained. Results of measurements were proposed to make several types of indices. The index expressions of measured parameters were found to be the most suitable for (a) evaluation and investigation o
