How to use Humic Acids Fertilizer Correctly?

Humic acid is black or brown amorphous organic polymer, soluble in water, but with colloidal properties, can improve soil structure and improve soil fertility; with chelation, can improve nutrient reactive phosphorus, potassium and trace elements and fertilizer utilization; also promote crop growth, improve the resistance of crops. In addition, complex NPK with humic acid on other elements also have a sustained effect.

Currently, the humic acid fertilizer are constantly in development, quality control of its products, mostly industry and local standards, application methods vary by product.

Water-soluble fertilizer containing humic acid is add the appropriate amount of humic acid NPK, or liquid or solid fertilizer made of trace elements. Industry technical standards (NY1106-2006) provides that humic acid content of humic acid fertilizer containing a large number of elements of type Ⅰ and type Ⅱ solid product of not less than 3% and 4%, NPK total content of not less than 35% and 20%; humic acid content of the liquid products were not less than 30g / L and 40g / L, total NPK content of not less than 350g / L and 200g / L. Humic acid and trace element content of humic acid fertilizer containing trace elements in type of not less than 3% and 6%. Low levels of water-soluble substances, solid and liquid products content shall not exceed 5.0% and 50g / L, respectively.

On the application method, water-soluble solid or liquid products mainly for fertilizer, seed fertilizer or soaking, Baptist roots.
