Humic Acid's Role in Improving Soil Quality and Plant Growth
What is Humus or Humic Acid?
The term "humus" dates back to the time of the Romans, when it was
frequently used to designate the soil as a whole. It was later
applied to the organic matter of soils and composts, or to
different fractions of this organic matter; as well as, to
complexes formed from a variety of natural organic substances.
Humus compounds are complex natural organic compounds that are
formed in soils from plant residues, by a process of
"humification". Humus materials are complex aggregate of brown to
dark colored amorphous substances, which have originated during the
decomposition of plant and animal residues by microorganisms, under
aerobic and anaerobic conditions, in soils, composts, peat bogs,
and water basins. Chemically, humus consists of certain
constituents of the original plant material resistant to further
decomposition; of substances undergoing decomposition; of complexes
resulting from decomposition, either by processes of hydrolysis or
by oxidation and reduction; and of various compounds synthesized by
"Humic acid" is the commercial term often used to refer to the
combined humic and fulvic acid content found in these naturally
occurring deposits. Humic acid is known to be among the most
bio-chemically active materials found in soil.
Why Use Humic Acid?
Today, there is a recognized and increasing use of humic acids for
their beneficial impact on the growth and cultivation of crops
(vegetable & non-vegetable), citrus, turf, flowers, and
particularly in organically-deficient soils. Humic acid is not a
fertilizer as it does not directly provide nutrients to plants, but
is a compliment to fertilizer. Benefits include:
- Addition of organic matter to organically-deficient soils
- Increase root vitality
- Improved nutrient uptake
- Increased chlorophyll synthesis
- Better seed germination
- Increased fertilizer retention
- Stimulate beneficial microbial activity
- Healthier plants and improved yields
How Does Humic Acid Improve Soil?
When applied to clay soils, humic acid can help break up compacted
soils, allowing for enhanced water penetration and better root zone
growth and development. When applied to sandy soils, humic acid
adds essential organic material necessary for water retention thus
improving root growth and enhancing the sandy soil's ability to
retain and not leach out vital plant nutrients.
How Does Humic Acid Improve Plant Growth?
As mentioned above, one way plant growth is improved is through the
structural improvement of both clay and sandy soil allowing for
better root growth development.
Plant growth is also improved by the ability of the plant to uptake
and receive more nutrients. Humic acid is especially beneficial in
freeing up nutrients in the soil so that they are made available to
the plant as needed. For instance if an aluminum molecule is binded
with a phosphorus one, humic acid detaches them making the
phosphorus available for the plant. Humic acid is also especially
important because of its ability to chelate micronutrients
increasing their bio-availability.
How Does Humic Acid Effect Microbial Activity and What is its Role?
The activities of beneficial soil microbes are crucial for the
sustainability of any soil and plant growth. Humic acid stimulates
microbial activity by providing the indigenous microbes with a
carbon source for food, thus encouraging their growth and activity.
Soil microbes are responsible for solubilizing vital nutrients such
as phosphorus that can then be absorbed by the humic acid and in
turn made available to the plant. Additionally, microbes are
responsible for the continued development of humus in the soil as
it continues to break down not fully decomposed organic matter.
This in-situ production of humus continues to naturally add to the
humic acid base and its benefits.
Humic Acid's Role in Fertilization
Humic acid is technically not a fertilizer, although in some walks
people do consider it that. Humic acid is an effective agent to use
as a complement to synthetic or organic fertilizers. In many
instances, regular humic acid use will reduce the need for
fertilization due to the soil's and plant's ability to make better
use of it. In some occurrences, fertilization can be eliminated
entirely if sufficient organic material is present and the soil can
become self sustaining through microbial processes and humus
