Photochemical release of humic and fulvic acid-bound metals from simulated soil and streamwater.
This study demonstrates the strong impact of photochemical degradation of soil dissolved organic matter (DOM) on its metal complexing capacity. The role of light in the fate of organically-bound metals transported from soils to surface waters was studied in laboratory experiments. We studied four humic and one fulvic acid isolates from different soil horizons in the Bohemian Forest (Czech Repub...
متن کاملDynamic conductivity measurements in humic and fulvic acid solutions.
Conductivity changes of dilute aqueous humic and fulvic acids solutions were monitored after the addition of small quantities of Cu, Cd, Pb, and Zn. The solutions were stirred at a constant and reproducible rate, and measurements proceeded until stable conductivities were attained. The values were compared to KCl reference solutions treated in an identical manner, and the results showed that th...
متن کاملOrganic Matter, Humus, Humate, Humic Acid, Fulvic Acid and Humin: Their Importance in Soil Fertility and Plant Health
Humic substances, such as those listed in the above title, play a vital role in soil fertility and plant nutrition. Plants grown on soils which contain adequate humin, humic adds (HAs), and fulvic adds (FAs) are less subject to stress, are healthier, produce higher yields; and the nutritional quality of harvested foods and feeds are superior. The value of humic substances in soil fertility and ...
متن کاملComplementary multianalytical approach to study the distinctive structural features of the main humic fractions in solution: gray humic acid, brown humic acid, and fulvic acid.
Previous studies have indicated that the main fractions of humic substances (HS), gray humic acid (GHA), brown humic acid (BHA), and fulvic acid (FA), present different molecular patterns in water solution that are probably associated with specific structural features. However, the techniques used in these previous studies did not permit clarification of the principal qualitative characteristic...
متن کاملLeachability of Cu and Ni in wood ash-amended soil as impacted by humic and fulvic acid
Land application is a cost-effective way of disposing of wood ash. However, high volume wood ash application tends to increase soil pH, solubilizing soil organic matter (SOM), and enhancing metal mobility. Column studies (1.5 20 cm) were conducted to determine the leachability of Cu and Ni in an ash-amended soil. In the first study, deionized water was used to leach three columns: ash, ash mixe...
