Difference Between Humic Acid and Fulvic Acid

Dec 29, 2011 · The key difference between humic acid and fulvic acid is that humic acid is not absorbed by plants whereas fulvic acid is absorbed. Moreover, fulvic acids have a lower molecular weight than humic acids. This is because the size of the humic acid molecule is larger than the size of the fulvic acid molecule. Another
