Benefits of Humic Acid for Plants Growth
The potassium, sodium, ammonium salt solution of the fulvic acid or the humic acid at a certain concentration can be applied to different growth stages of the crops in such ways as dipping root, the spraying and the root application and etc. So that the corresponding stimulation can be produced. The growth and development of the crops can be promoted. Early maturity, yield increased, and quality improved.
Promote seed germination, root and vegetative growth
The stimulation of humic acid can lead the seed to germinate for 2 to 3 days in advance. The germination rate is high. The seedling is full and strong. The action on the root system can promote the vitality. The good effect on the root system was made to give the researchers the title of the “root fertilizer” of the humic acid. In addition to the root system, the growth of the vegetative body on the ground is also promoted. It is worth mentioning that the stimulation of humic acid is especially significant in the early stage of crop fruiting.
Regulate the metabolic process of plants
Humic acid for plants contains phenolic hydroxyl group, quinone group and other active functional groups. Which can promote the increase of enzyme activity in planta. Increase the intensity of respiration and photosynthesis. And benefit the synthesis, operation and accumulation of substances.
Plant metabolism, decomposition and synthesis of substances are completed by various enzymes. Which are closely related to life.The results showed that humic acid promoted the activities of polyphenol oxidase catalase, ascorbic acid oxidase and invertase.The enhancement of enzyme activity speeds up the metabolic process. Increases the material accumulation, and makes crops mature earlier.
