Fulvic acid function in enzyme activity and photosynthesis and respiration

Fulvic acid function when use as Foliar application or application of fulvic acid in nutrient solution can cause an increase in chlorophyll content and even prevent yellowing in the absence of cations, since fulvic acid promotes the absorption of magnesium or iron, thereby increasing the chlorophyll content. An increase in chlorophyll content leads to enhanced photosynthesis and an increase in dry matter accumulation.

The fulvic acid function on respiration has been studied more. For respiration, fulvic acid promotes more than humic acid. fulvic acid ca n directly participate in respiration, in the case of normal O2 concentration,
fulvic acid enters the plant and acts as an H receptor.

The phenol and hydrazine in the fulvic acid molecule are mutually transformed, which is both an activator of oxygen and a carrier of H, which increases the redox potential in plants and enhances the respiration of plants. fulvic acid can enter cells and bind to mitochondria, which proves that fulvic acid can directly affect respiration.

fulvic acid with phenolic and sulfhydryl groups participates in the nitridation-reduction process, resembling a free radical in the form of a semiquinone. Therefore, fulvic acid is very suitable for direct participation in the electron transfer system associated with breathing, and can participate in the oxidation-reduction reaction together with the transfer metal. The above viewpoint is further affirmed by the fact that fulvic acid can promote the activity of cytochrome oxidase.

In addition, fulvic acid can also enhance the disease resistance of fruit trees and improve the quality of food, vegetables, fruits, sugar cane, tobacco and other products. It can be seen that fulvic acid has a wide range of effects on plant growth, development, physiology and so on.

The mineral content of our soils is extremely low right now. Farm lands have been overused and minerals are not being replaced the way nature intended. Even organic foods can be deficient because of our depleted soils. Scientists feel this could account for the dramatic rise in health problems that plague our “humic acid/fulvic starved” society.Foods with high humic acid content are very difficult to obtain, making it essential that we supplement our diets with this essential molecule.

Therefore, the study of fulvic acid has both theoretical significance and application value.
