                              The Wonder treatment for Soil!

It has been a known fact for thousands of years that decayed organic substances when
added to soil increase its fertility. The use of manure to increase soil fertility has been a
practice common for many centuries. But little was known about the exact mechanism.
Modern science has now unlocked the secret ….and the secret is Humic Acids!

What are Humic Acids?
Humic acids are naturally occurring substances having aliphatic-aromatic and highly
functionalized molecules. Humic acids was formed as a result of bacterial action on
buried fossils of plants. The decomposition and subsequent changes took place over
millions of years. There are several sources of humic acids but the most commonly used
and best source is from fossil mineral classified as leonardite. Nitrogen, Phosporous and
sulphuer which are the major plant nutrients are also present in Humic acids.

Major Advantages of Humic Acid
Following are the major advantages of using Humic acid which are also well understood.
    • Humic acids assists in the transfer of micro nutrients from soil to plants
    • They enhance water retention in soil and in some cases, the water requirement is
       reduced by half primarily because of their colloidal nature
    • The addition of humic acid increase seed germination rate because they carry with
       them hormones and vitamins
    • Humic acid absorbs fertilizer and increase their availability to the plant roots
    • The presence of Humic acid in soil stimulates the growth of micro-flora

Working of Humic Acid
Humic acid is a complex chemical and it’s actions are now well understood, lets
understand how Humic acid works
High Water absorption and Roots growth
The presence of salts neutralizes the negative charges between clay particles, when these
charges are neutralized the clay particles no longer repel each other. As a consequence
clay becomes compact; the compact clay has two major disadvantages. Firstly it restricts
the development of roots and secondly it slows the penetration of water in the soil; the
slow penetration of water means a major portion is lost to evaporation. Humic Acid has
the ability to chelate ions and segregate the clay particles thereby increasing water
absorption in soil and facilitating growth of roots.

Provision of Micro-nutrients
Humic Acid has the ability to pick up positive ions (many metallic ions like those of Iron
and copper and non metallic ions of Boron and Chlorine). These ions are then exchanged
with the roots, which are negatively charged in comparison to Humic acid. This process
is called ion exchange. The positive ions enter through the roots and thus the plant
requirement of micro nutrients is met.

Fertilizer Usage and Stimulation of Micro-flora
The fertilizer components are readily absorbed by humic acid and through Ion exchange
the component are released to plant roots. Humic acid becomes a source of phosphate and
carbon which in turn stimulate micro-floral growth. The micro flora secret enzyme which
act as catalyst releasing calcium and phosphorous ions from insoluble calcium phosphate
and ions from iron phosphate. The ions again are then taken up by plant roots.

Occasional Advantages of Humic Acid
There are a number of other advantages which have been noted by scientists but the exact
mechanism is not well known. Research is still going on but we should not discount these
advantages at all
   • Plants which have been treated with Humic acid are know to grow better under
       the following stresses
           o Drought Stress
           o Heat Stress
           o Salt Stress
   • Root development is significantly better in soils with humic acid. The root mass,
       length and initials were more in soil with humic acid.
   • Chlorophyll production is increased by up to 60% in soils with Humic acid
   • Humic acid has also been noted to be responsible in enabling the genetic
       mechanism of plants to combat pest and disease attacks.
   • Plants in soil with humic acid have also been noted to have absorbed significantly
       less harmful pesticides and herbicides
Market Options
  • As a brownish black powder having 50% humic acids, balance being clay, silica
     and 2-3% of macro and micro nutrients like Phosphorous, potassium, zinc, iron
     and sulphur. In addition it contains up 3% humins and falvic acids.
