What's the effect of humic acid in agriculture

Humic Acid is a mixture of natural organic macromolecular compounds, which exists in all soils, plants and animals,and have been widely used in agricultural production in recent years due to their unique physiological functions.Adding a small amount of humus to an acre of soil can improve soil condition.

Features of using Humic acid 

Improved soil structure, prevents high water and nutrient losses in bad soils.

Regulates the pH-value of soils.

Enhances plant’s nature resistance against diseases and pests.

Stimulates root growth, and improves the plant’s uptake of nutrients and water.

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.

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