At present, the source humic acid is an organic substance formed during the crustal change. The main elements are carbon, oxygen, hydrogen, nitrogen and sulfur. The carbon content is the highest. It is worth noting that the organic matter is not necessarily humic. Acid, but humic acid must be a good organic matter.

Ore source humic acid is an organic carrier with good biological activity and various functional groups. It is also an intermediate substance with metabolic functions of plant respiration and photosynthesis. Therefore, humic acid has great solubility and powerful functions. Higher benefits have been achieved in agriculture.

Ore source humic acid enhances crop stress resistance

(1). Humic acid stimulates crop growth, promotes rooting and enhances photosynthesis;
(2). Humic acid has a function similar to plant growth hormone;
(3). Humic acid enhances crop stress resistance, drought resistance, cold resistance, and disease resistance;

Improvement of soil physical and chemical properties by ore source humic acid

(1). Humic acid improves soil aggregate structure, has adhesiveness, forms soil structure, and increases gas permeability;
(2). Humic acid regulates soil pH, which is itself a dilute weak acid, has strong buffering properties, and improves soil pH;
(3). Humic acid increases the ground temperature, and the humic acid has a deep black color, which can absorb the photothermal energy of the soil.
(4). Humic acid enhances the softness of the soil and makes the soil softer.

Soil Texture

Humic substances are key components of a friable (loose) soil structure. As the humic substances become intimately associated with the mineral fraction of the soil, colloidal complexes of humus-clay and humus silt aggregates are formed. These aggregates are formed by electrical processes which increase the cohesive forces that cause very fine soil particles and clay components to attract each other. Once formed these aggregates help create a desirable crumb structure in the top soil, making it more friable. Soils with good crumb structure have improved tilth and more porous openings (open spaces). These pores allow for gaseous interchange with the atmosphere, and for greater water infiltration.
