Fulvic acid

Fulvic Acid

Fulvic acid, a short carbon chain small molecular structure material extracted from natural humic acid, is the water-soluble part of humic acid with the smallest molecular weight and the highest active group content, and is widely found in nature.

Among them, the proportion of fulvic acid in the soil is the largest, mainly composed of natural, yellow to dark brown, amorphous, gelatinous, organic polyelectrolytes with fat and aromaticity, with smaller molecular weight and highest active group content. Cannot be represented by a single chemical structure.

Fulvic acid is the best ingredient in soil humic acid.

It is also a humic acid product with a wide range of use and high economic benefits. It can increase grain yield, restore soil fertility, improve soil, improve ground temperature, promote root development, effectively adjust soil pH, solve soil compaction, reduce fertilizer application and increase The quality of agricultural products has special effects.

In the case of dry climate, it can reduce the degree of stomatal opening of crops, commonly known as “drought resistance No.1”. Up to now, there are still large market and competitive advantages in plant growth agents, anti-reverse agents, fluid fertilizers, pharmaceutical preparations and cosmetics.

Fulvic acid is a gray-black powdery substance that is soluble in water.

It is a plant growth regulator that promotes plant growth and plays an important role in combating drought. It can improve plant resilience, increase yield and improve quality. The main application objects are wheat, corn, sweet potato, millet, rice, cotton, peanut, rape, tobacco, sericulture, melon and fruit, and vegetables.

Fulvic Acid Structure

The fulvic acid contains functional groups such as carboxyl group and phenolic hydroxyl group, which has strong complexation, chelation and surface adsorption ability, can reduce the loss of ammonium nitrogen, increase the moving distance of phosphorus in the soil, and inhibit the fixation of water-soluble phosphorus in the soil.

  1. Elemental composition: C 54.82% H 2.29% O 41.14% N 0.66% S 1.09%.
  2. Functional group content: total acid group 8.76 meq/g (hydroxy 6.12 meq/g, phenolic hydroxyl 2.64 meq/g).
