The Functions of Humic Acid Fertilizer

• The function of soil improvement

Humic acid fertilizers contain a large amount of organic matter and organic colloid, which can cement dispersed and structureless soil particles together. Form water-stable aggregates that are not easy to loosen when exposed to water. As a result, soil porosity increases, bulk density decreases, soil aeration, water permeability and moisture retention ability are enhanced, and tillage becomes better.It has a good effect on improving the poor soil with sticky and sandy soil.

Humic acid has a high cation exchange capacity, usually up to 300~500cmol(+)/kg.Therefore, the application in the south of China can complexate free iron and aluminum ions to form complexes and improve the utilization rate of phosphate fertilizer.Applying saline soils in the north, but on the soil of sodium, calcium, Mg, iron, aluminium, chloride and sulfate has a strong exchange capacity and adsorption, reduce the chloride, sulfate concentration in the soil solution, reducing salt and its harm to crops, can strengthen the buffering capacity of the soil.

• The nutrition function

In addition to humic acid, humic acid fertilizers contain a certain amount of available nitrogen, phosphorus and potassium nutrients, which can be absorbed by crops.In addition, due to the strong adsorption capacity of humic acid, it can activate mineral elements in the soil, such as phosphorus, potassium, calcium, magnesium and trace elements, so as to improve the availability of nutrients.Humic acid has a strong ability to adsorb ammonium positive ions (NH4 +). Combined with ammonium nitrogen fertilizer, it can improve the availability of phosphorus and reduce the fixation of phosphorus.Meanwhile, humic acid can stimulate the development of root system, increase the contact area between root system and fertilizer and increase the amount of organic acid secreted by root system, so as to improve the utilization rate of root system to insoluble nutrients.
In addition, humic acid and other low molecular humic acid on potassium silicate, potassium feldspar and other corrosion, can be slowly decomposed, increase the release of potassium.The chelating application of humic acid also activates trace elements. It enables the insoluble trace elements to form soluble chelates for absorption by the root and helps them to move upward from the root.

• Stimulating effect

It can promote the germination of crop seeds, improve the germination rate of seeds, promote the growth of roots, improve the ability of roots to absorb water and nutrients, increase tillering and early maturation.The stimulating effect of humic acid fertilizers is mainly caused by the presence of phenols and quinones in the molecular structure of humic acid, which are involved in the REDOX process in crops and enhance the activities of various phenols in crops, such as phenolic oxidase, catalase and ascorbic oxidase.
Polyphenol-quinone system is not only the activator of oxygen, but also the carrier of hydrogen, so it can promote the respiration of crops, increase the nutrient absorption and dry matter accumulation, which is beneficial to the growth and increase of crops.
