- Humic acid is a
group of molecules that bind to, and help plant roots receive,
water and nutrients. High humic acid levels can dramatically
increase yields. Humic acid deficiency can prevent farmers and
gardeners from growing crops with optimum nutrition.
- Humic acids
increase the water infiltration and water-holding capacity of
the soil. They greatly improve the soil, increase plant root
growth and metabolism, enhance seed germination, and help plants
deal with environmental stresses. They remove odours in slurry
and compost piles, and keep irrigation lines clean.
- Humic
substances are formed by the microbial degradation of dead plant
matter, such as lignin and charcoal. ... The humic and fulvic
acids are extracted as a colloidal sol from soil and other solid
phase sources into a strongly basic aqueous solution of sodium
hydroxide or potassium hydroxide
- Fulvic acid is
the low-molecular-weight (LMW) portion of humic substances. ...
Because of its small molecular size, fulvic acid is able to
penetrate the cell and mitochondria of the cell, where humic
acid can not. The LMW fulvic acids have higher oxygen but lower
carbon contents than the HMW humic acids.
