byacidificationof the alkaline soil extract. Fulvic acid is defined as that component of humic substances that remains soluble in the alkaline soil extract after acidification; that is, it is soluble in both dilute base and acid. Fulvic acid has a lower molecular weight and a higher content of...
Molecular weights of humic acids separated from two lake and three marine sediments were measured by gel filtration through Sephadexes. The results indicate that mol. wt. of humic acid distributes from less than 700 to over 200,000. On the basis of mol. wt. the humic acids are divided int...
