Fulvic Acid Description

Fulvic acid is completely soluble in water, acidic and alkaline solution. Usually used for drip irrigation and forliar spray.Will have good function if mix use with NPK fertilizer.

Main Function

  1. Besides the basic function of humic acid, it has the special function owning to high content of fulvic acids.Like drought-resistent, counter disease, growth regulator, slow-release pesticide synergist, chemical elements complexing agent, help the plants germination and grow root in agriculture used as foliar spray and drip irrigation.
  2. Fulvic acid does not have a uniform molecular structure and is a relatively large molecule with a certain range of molecular weight (500 to 2,000). As a characteristic of the molecule, fulvic acid has many carboxyl groups and phenolic alcohol groups in the molecule. These multiple groups (ligands in complex chemistry) stably wrap the mineral components in the soil and efficiently transport them into plant cells (chelating effect). Iron and magnesium ions are indispensable for photosynthesis, and fulvic acid promotes the function of transporting those ions in the soil into plant cells by a chelating effect, thereby leading to activation of photosynthesis.
  3.  Efficient absorption of fertilizer In situations where the fertilizer component is not sufficiently dissolved in the soil, the addition of fulvic acid promotes  the elution of the fertilizer component into the soil.
  4. Buffering of soil pH (when using for basic soil, or for acidic soil with basic material)Fulvic acid has the effect of buffering soil pH. Specifically, when used in an alkaline soil, the soil pH is shifted to neutral and stabilized. On the other hand, for acidic soils, by using together with alkaline materials, soil pH is shifted to neutral and the pH fluctuation is reduced
  5. Promotion of soil aggregation
    Aggregation of soil plays an important role in plant growth. The soil aggregation is promoted by fulvic acid (humic substances) mediating iron and aluminum, one of the constituents of the soil particles, to bind the soil particles together.
  6. Control of damge from salinity
    Crops do not grow in a salty soil environment. In many soils with a high salinity, salts (such as NaCl) are strongly sandwiched in the crystal structure of the soil, and are not carried out of the crystal lattice in rain or the like. When fulvic acid is used, the salt trapped in the soil crystals is carried out of the crystals and flows out due to rain or the like. Utilizing this principle, a ridge having a soil environment with low salt content can be created by forming a ridge and providing a step.
  7. Improvement of plant robustness
    The effect of facilitating the intake of nutrients and promoting the absorption of iron and magnesium ions required for photosynthesis improves the plant’s overall robustness against pests and adverse natural environments.


  1. Drip irrigation: 0.5-1kgs per hectare
  2. Foliar spray: 300-500g per hectare
  3. To produce liquid solution, put 1 gram fulvic acid into 0.5 liter of water at a very slow speed; agitate the solution at a constant speed. The solution can be applied 3-5liter per Ha. Please make sure the solution is uniform before transfer to the spray tank.
