Humic Acid Enhances Stress Resistance Properties

Humic acid can reduce the stomatal opening intensity of plant leaves and reduce leaf transpiration, thereby reducing water consumption, improving the water status in the plant, ensuring normal growth and development of crops under drought conditions, and enhancing drought resistance. Humic acid is mostly an amphoteric colloid with high surface activity and an inhibitory effect on fungi. It can enhance the cold resistance of crops, is easily adsorbed by cell membranes, changes the permeability of cell membranes, promotes the absorption of inorganic nutrients, prevents rot and root rot, and reduces pests and diseases. .
