Use of humic acid in organic farming

22/08/2021 Sunday August 22nd, 2021

Humic acid is a mineral produced from the mine commonly known as a soil conditioner. Which increases the fertility of barren land. Improves soil structure and gives it a new lease of life.
Its most important function is to make the soil porous so that the roots can grow more.
This accelerates the action of photosynthesis, which leads to greenness in the plant and the growth of branches.
Develops tertiary roots of plants so that the absorption of nutrients from the soil can be increased.
Increases the fertility of the soil by increasing the metabolic activities of plants.
It increases the yield of the crop by increasing the number of flowers and fruits in the plant.
Increases seed germination capacity and protect plants from adverse environments.
