• Improves structure of soil, prevents high water and nutrient losses in light or sandy soils.
• Regulates the pH-value of soils.
• Promotes the conversion of nutrient elements (N, P, K + Fe, Zn and other trace elements) into forms available to plants.
• Stimulates root growth, especially vertically and enable better uptake of nutrients.
• Increases the quality of yields.

What’s more, In addition to these above benefits, its role in plant stress resistance has also received increasing attention.

• Plant drought stress

Under drought conditions, the application of humic acid-containing fertilizer can promote the increase of proline content in plant leaves to improve the drought resistance of crops.

• Plant salt and alkali stress

Humic acid can enhance the salt resistance by regulating the change of fructose concentration and alleviating the damage of material membrane under salt stress.

• Plant temperature stress

Under low temperature stress, humic acid can increase crops’s proline and abscisic acid content, reduce the spead of transpiration rate, stomatal conductance and net photosynthetic rate of plants.

Under high temperature stress, It enhances the heat resistance of crops by increasing the activities of crop superoxide dismutase and peroxidase.

• Plant disease resistance：

Humic acid can promote growth by increasing the sugar content and chlorophyll content of leaves, which indirectly improves the disease resistance of crops.

When you decide to make humic acid as liquid and powder yourself. there is a need for good and usable formulation. Because of this formulation is needed in order to decide which raw materials and in what quantites should be used.
