Extant parts of organic matters which have been consumed and transformed by a large number of soil organisms is called " Humus ". Fulvic acid is among the humic compounds and a mixture of polyphenolic acid compounds which are produced as a result of decomposing organic matters such as dead plants, microbes and animals through chemical and biological processes. Fulvic acids are the specific parts of humus which are dissolved in water under any pH conditions. Their color usually varies from light to brownish yellow. Fulvic acids are produced in primary stages of humus formation process. The relative amount of humuc and fulvic acids depends on the different soil types and management policies. Humus of forest soils contains high level of fulvic acid. On the other hand, humus in agricultural areas contains much more humic acids instead.

- Non-toxic - Increases cell division and longitudinal cell growth. Increases the growth of roots. - Fulvic acid increases the absorption of oxygen through producing chlorophyll and increases the absorption of nutrients through increasing membrane permeability. - Leads to increasing the photosynthesis in long-term cloudy durations. - Fulvic acid is a powerful and natural chelating agent which leads in reduction of oxidation, conservation of metal elements into absorbable and molecular size foods and allows rapid entry through plant cells. - During droughts, fulvic acid protects the plant through increasing the moisture. - Fulvic acid is also capable of detoxifying contaminations of soil. These acids absorb the contaminations and accelerate their decomposition. - Fulvic acid dissolves silica and presents the plant so many advantages from this element. - Fulvic acid is also in charge of increasing the opening and perspiration of the pores, helping the breathing process and improving respiration of beneficial microorganisms as well. - Fulvic acid affects so many enzymatic processes directly and improves plant's immune system.

- Increases germination and seed growth - Improves the growth of roots and branches - Increases the plant's resistance to diseases, pests and environmental changes. - Increases the absorption of food elements. - Increases the protein metabolism - Increases the enzyme's activities - Increases the membrane permeability - Improves cell division and their longitudinal growth - Increases the level of mineral synthesis - Helps in fertilizing soils - Prevents the heavy metal elements to be absorbed - Improves the growth and function of products. - Contributes in producing chlorophyll - Improves plant's breathing process.
