What Does Humic Acid Do For Plants?

What are humic acids?
Humic acids are an excellent natural and 100% organic way to provide plants and soil with a concentrated dose of essential nutrients, vitamins and trace elements. The best source of humic acid is derived from mid western sedimentation layers called Leonardite. Humic acids are not fertilizers. They act as a bio-stimulant for the plant. Humic acids enhance plant growth particularly biomass production and fertility of the soil. As humic acids are completely decomposed, they do not enter into nutritional competition with plants for nutrients such as for nitrogen. Current scientific studies show that the fertility of soil is determined to a very large extent by the content of humic substance in matrix. Their high cation-exchange capacity (movment of ions across the root), oxygen content as well as high water holding capacity are but a few reasons for using humic acids in the improvement of soil fertility and plant growth.

Benefits of Humic Acids:

The most important features of humic acids lie in their ability to:
Bind available insoluble metal ions, oxides and hydroxides, slowly releasing them to roots. 
Prevent water and nutrient losses in light, sandy soils.
Increase aeration and water infiltration in clay soils.  
Stimulate fine root mass development  rapidly establishing new plantings.
Humic acids are rich in both organic and mineral substances essential to plant growth.
When Humic Acids enter plants at early stages of development, they result in increased cell division and root development hastening establishment. Also, humic acids act as a natural chelator by enhancing the availability of iron thus increased photosynthesis and sugar production translating into increased storage for defense.
Humic acids decrease plant stress through enhancement of physiological reactions within the plant, such as increased root formation, particularly fine absorbing roots, thus resulting in greatly increased resource allocation to aerial tissues for growth.
